Creating a Simple RESTful API in Go

In this tutorial demonstrates how you can create a simple RESTful JSON api using Go(Lang)

If you are writing any form of web application, then you are most likely interfacing with 1 or more REST APIs in order to populate the dynamic parts of your application and to perform tasks such as updating or deleting data within a database.

In this tutorial, you are going to be building a fully-fledged REST API that exposes GET, POST, DELETE and PUT endpoints that will subsequently allow you to perform the full range of CRUD operations.

In order to keep this simple and focus on the basic concepts, we won’t be interacting with any backend database technologies to store the articles that we’ll be playing with. However, we will be writing this REST API in such a way that it will be easy to update the functions we will be defining so that they make subsequent calls to a database to perform any necessary CRUD operations.

Source Code - The full source code for this article can be found here: TutorialEdge/create-rest-api-in-go-tutorial## Prerequisites

  • You will need Go version 1.11+ installed on your development machine.


By the end of this tutorial, you will know how to create your own REST-ful APIs in **Go **that can handle all aspects of. You will know how to create **REST **endpoints within your project that can handle POST, GET, PUT and DELETE HTTP requests.

REST Architectures

REST is everywhere these days, from websites to enterprise applications, the RESTful architecture style is a powerful way of providing communication between separate software components. Building REST APIs allow you to easily decouple both consumers and producers and are typically stateless by design.

Note - If you wish to learn more about the basics of REST APIs then check out What Are RESTful APIs?## JSON

For the purpose of this tutorial I’ll be using JavaScript Object Notation as a means of sending and receiving all information and thankfully Go comes with some excellent support for encoding and decoding these formats using the standard library package, encoding/json.

Note - For more information on the encoding/json package check out the official documentation: encoding/json## Marshalling

In order for us to easily We can easily convert data structures in GO into JSON by using something called marshalling which produces a byte slice containing a very long string with no extraneous white space.

Getting Started with A Basic API

To get started we will have to create a very simple server which can handle HTTP requests. To do this we’ll create a new file called main.go. Within this main.go file we’ll want to define 3 distinct functions. A homePage function that will handle all requests to our root URL, a handleRequests function that will match the URL path hit with a defined function and a main function which will kick off our API.


package main

import (

func homePage(w http.ResponseWriter, r *http.Request){
    fmt.Fprintf(w, "Welcome to the HomePage!")
    fmt.Println("Endpoint Hit: homePage")

func handleRequests() {
    http.HandleFunc("/", homePage)
    log.Fatal(http.ListenAndServe(":10000", nil))

func main() {

If we run this on our machine now, we should see our very simple API start up on port 10000 if it’s not already been taken by another process. If we now navigate to <a href="http://localhost:10000/" target="_blank">http://localhost:10000/</a> in our local browser we should see Welcome to the HomePage! print out on our screen. This means we have successfully created the base from which we’ll build our REST API.

Note - If you want a more in-depth tutorial on how to create a go based web server then check out this tutorial here: Creating a Simple Web Server with Go(Lang)## Our Articles Structure

We’ll be creating a REST API that allows us to CREATE, READ, UPDATE and DELETE the articles on our website. When we talk about CRUD APIs we are referring to an API that can handle all of these tasks: Creating, Reading, Updating and Deleting.

Before we can get started, we’ll have to define our Article structure. Go has this concept of structs that are perfect for just this scenario. Let’s create an Article struct that features a Title, a Description (desc) and Content like so:

type Article struct {
    Title string `json:"Title"`
    Desc string `json:"desc"`
    Content string `json:"content"`

// let's declare a global Articles array
// that we can then populate in our main function
// to simulate a database
var Articles []Article

Our Struct contains the 3 properties we need to represent all of the articles on our site. In order for this to work, we’ll also have to import the "encoding/json" package into our list of imports.

Let’s now update our main function so that our Articles variable is populated with some dummy data that we can retrieve and modify later on.

func main() {
    articles := Articles{
        Article{Title: "Hello", Desc: "Article Description", Content: "Article Content"},
        Article{Title: "Hello 2", Desc: "Article Description", Content: "Article Content"},

Perfect, let’s now move on to creating our /articles endpoint which will return all of the articles that we’ve just defined here.

Retrieving All Articles

In this part of the tutorial we are going to create a new REST endpoint which, when hit with a HTTP GET request, will return all of the articles for our site.

We’ll first start off by creating a new function called returnAllArticles, which will do the simple task of returning our newly populated Articles variable, encoded in JSON format:


func returnAllArticles(w http.ResponseWriter, r *http.Request){
    fmt.Println("Endpoint Hit: returnAllArticles")

The call to json.NewEncoder(w).Encode(article) does the job of encoding our articles array into a JSON string and then writing as part of our response.

Before this will work, we’ll also need to add a new route to our handleRequests function that will map any calls to <a href="http://localhost:10000/articles" target="_blank">http://localhost:10000/articles</a> to our newly defined function.

func handleRequests() {
    http.HandleFunc("/", homePage)
    // add our articles route and map it to our 
    // returnAllArticles function like so
    http.HandleFunc("/articles", returnAllArticles)
    log.Fatal(http.ListenAndServe(":10000", nil))

Now that we’ve done this, run the code by typing go run main.go and then open up <a href="http://localhost:10000/articles" target="_blank">http://localhost:10000/articles</a> in your browser and you should see a JSON representation of your list of articles like so:

http://localhost:10000/articles response

    Title: "Hello",
    desc: "Article Description",
    content: "Article Content"
    Title: "Hello 2",
    desc: "Article Description",
    content: "Article Content"

We’ve successfully defined our first API endpoint.

In the next part of this series, you are going to update your REST API to use a gorilla/mux router instead of the traditional net/http router.

Swapping the routers will enable you to more easily perform tasks such as parsing any path or query parameters that may reside within an incoming HTTP request which we will need later on.

Getting Started with Routers

Now the standard library is adequate at providing everything you need to get your own simple REST API up and running but now that we’ve got the basic concepts down I feel it’s time to introduce third-party router packages. The most notable and highly used is the gorilla/mux router which, as it stands currently has 2,281 stars on Github.

Building our Router

We can update our existing main.go file and swap in a gorilla/mux based HTTP router in place of the standard library one which was present before.

Modify your handleRequests function so that it creates a new router.


package main

import (

… // Existing code from above
func handleRequests() {
    // creates a new instance of a mux router
    myRouter := mux.NewRouter().StrictSlash(true)
    // replace http.HandleFunc with myRouter.HandleFunc
    myRouter.HandleFunc("/", homePage)
    myRouter.HandleFunc("/all", returnAllArticles)
    // finally, instead of passing in nil, we want
    // to pass in our newly created router as the second
    // argument
    log.Fatal(http.ListenAndServe(":10000", myRouter))

func main() {
    fmt.Println("Rest API v2.0 - Mux Routers")
    Articles = []Article{
        Article{Title: "Hello", Desc: "Article Description", Content: "Article Content"},
        Article{Title: "Hello 2", Desc: "Article Description", Content: "Article Content"},

When you now run this, you will see no real change to the way our system works. It will still start up on the same port and return the same results depending on what endpoints you hit.

The only real difference is that we now have a gorilla/mux router which will allow us to easily do things such as retrieve path and query parameters later on in this tutorial.

$ go run main.go

Rest API v2.0 - Mux Routers

Path Variables

So far so good, we’ve created a very simple REST API that returns a homepage and all our Articles. But what happens if we want to just view one article?

Well, thanks to the gorilla mux router we can add variables to our paths and then pick and choose what articles we want to return based on these variables. Create a new route within your handleRequests() function just below our /articles route:

myRouter.HandleFunc("/article/{id}", returnSingleArticle)

Notice that we’ve added {id} to our path. This will represent our id variable that we’ll be able to use when we wish to return only the article that features that exact key. For now, our Article struct doesn’t feature an Id property. Let’s add that now:

type Article struct {
    Id      string `json:"Id"`
    Title   string `json:"Title"`
    Desc    string `json:"desc"`
    Content string `json:"content"`

We can then update our main function to populate our Id values in our Articles array:

func main() {
    Articles = []Article{
        Article{Id: "1", Title: "Hello", Desc: "Article Description", Content: "Article Content"},
        Article{Id: "2", Title: "Hello 2", Desc: "Article Description", Content: "Article Content"},

Now that we’ve done that, in our returnSingleArticle function we can obtain this {id} value from our URL and we can return the article that matches this criteria. As we haven’t stored our data anywhere we’ll just be returning the Id that was passed to the browser.

func returnSingleArticle(w http.ResponseWriter, r *http.Request){
    vars := mux.Vars(r)
    key := vars["id"]

    fmt.Fprintf(w, "Key: " + key)

If we navigate to <a href="http://localhost:1000/article/1" target="_blank">http://localhost:1000/article/1</a>after we’ve now run this, you should see Key: 1 being printed out within the browser.

Let’s use this key value to return the specific article that matches that key.

func returnSingleArticle(w http.ResponseWriter, r *http.Request) {
    vars := mux.Vars(r)
    key := vars["id"]

    // Loop over all of our Articles
    // if the article.Id equals the key we pass in
    // return the article encoded as JSON
    for _, article := range Articles {
        if article.Id == key {

Run that by calling go run main.go and then open up <a href="http://localhost:10000/article/1" target="_blank">http://localhost:10000/article/1</a> in your browser:

http://localhost:10000/article/1 response

Id: "1",
Title: "Hello",
desc: "Article Description",
content: "Article Content"

You will now see the article matching the key 1 returned as JSON.

Creating and Updating Articles

In this part of the tutorial, you are going to build the Create, Update and DELETE part of a CRUD REST API. We have already covered the R with the ability to read both single articles and all articles.

Creating new Articles

Once again, you will need to create a new function which will do the job of creating this new article.

Let’s start off by creating a createNewArticle() function within our main.go file.

func createNewArticle(w http.ResponseWriter, r *http.Request) {
    // get the body of our POST request
    // return the string response containing the request body    
    reqBody, _ := ioutil.ReadAll(r.Body)
    fmt.Fprintf(w, "%+v", string(reqBody))

With this function defined, you can now add the route to the list of routes defined within the handleRequests function. This time however, we’ll be adding .Methods("POST") to the end of our route to specify that we only want to call this function when the incoming request is a HTTP POST request:

func handleRequests() {
    myRouter := mux.NewRouter().StrictSlash(true)
    myRouter.HandleFunc("/", homePage)
    myRouter.HandleFunc("/articles", returnAllArticles)
    // NOTE: Ordering is important here! This has to be defined before
    // the other `/article` endpoint. 
    myRouter.HandleFunc("/article", createNewArticle).Methods("POST")
    myRouter.HandleFunc("/article/{id}", returnSingleArticle)
    log.Fatal(http.ListenAndServe(":10000", myRouter))

Try running this again and then try submitting a HTTP POST request which contains the following POST body:

    "Id": "3", 
    "Title": "Newly Created Post", 
    "desc": "The description for my new post", 
    "content": "my articles content" 

Our endpoint will trigger and subsequently echo back whatever value was in the request body.

Now that you have validated your new endpoint is working correctly, let’s update our createNewArticle function so that it unmarshals the JSON in the request body into a new Article struct which can subsequently be appended to our Articles array:

func createNewArticle(w http.ResponseWriter, r *http.Request) {
    // get the body of our POST request
    // unmarshal this into a new Article struct
    // append this to our Articles array.    
    reqBody, _ := ioutil.ReadAll(r.Body)
    var article Article 
    json.Unmarshal(reqBody, &article)
    // update our global Articles array to include
    // our new Article
    Articles = append(Articles, article)


Awesome! If you run this now and send the same POST request to your application, you will see that it echoes back the same JSON format as before, but it also appends the new Article to your Articles array.

Validate this now by hitting the <a href="http://localhost:10000/articles" target="_blank">http://localhost:10000/articles</a>:

http://localhost:10000/articles response

        "Id": "1",
        "Title": "Hello",
        "desc": "Article Description",
        "content": "Article Content"
        "Id": "2",
        "Title": "Hello 2",
        "desc": "Article Description",
        "content": "Article Content"
        "Id": "3",
        "Title": "Newly Created Post",
        "desc": "The description for my new post",
        "content": "my articles content"

You have now successfully added a Create function to your new REST API!

In the next section of this tutorial, you are going to look at how you can add a new API Endpoint which will allow you to delete Articles.

Deleting Articles

There may be times where you need to delete the data being exposed by your REST API. In order to do this, you need to expose a DELETE endpoint within your API that will take in an identifier and delete whatever is associated with that identifier.

In this section of this tutorial, you are going to be creating another endpoint which receives HTTP DELETE requests and deletes articles if they match the given Id path parameter.

Add a new function to your main.go file which we will call deleteArticle:

func deleteArticle(w http.ResponseWriter, r *http.Request) {
    // once again, we will need to parse the path parameters
    vars := mux.Vars(r)
    // we will need to extract the `id` of the article we
    // wish to delete
    id := vars["id"]

    // we then need to loop through all our articles
    for index, article := range Articles {
        // if our id path parameter matches one of our
        // articles
        if article.Id == id {
            // updates our Articles array to remove the 
            // article
            Articles = append(Articles[:index], Articles[index+1:]...)


Once again, you will need to add a route to the handleRequests function which maps to this new deleteArticle function:

func handleRequests() {
    myRouter := mux.NewRouter().StrictSlash(true)
    myRouter.HandleFunc("/", homePage)
    myRouter.HandleFunc("/articles", returnAllArticles)
    myRouter.HandleFunc("/article", createNewArticle).Methods("POST")
    // add our new DELETE endpoint here
    myRouter.HandleFunc("/article/{id}", deleteArticle).Methods("DELETE")
    myRouter.HandleFunc("/article/{id}", returnSingleArticle)
    log.Fatal(http.ListenAndServe(":10000", myRouter))

Try sending a new HTTP DELETE request to <a href="http://localhost:10000/article/2" target="_blank">http://localhost:10000/article/2</a>. This will delete the second article within your Articles array and when you subsequently hit <a href="http://localhost:10000/articles" target="_blank">http://localhost:10000/articles</a> with a HTTP GET request, you should see it now only contains a single Article.

Note - To keep this simple, we are updating a global variable. However, we aren’t doing any checks to ensure that our code is free of race conditions. In order to make this code thread-safe, I recommend checking out my other tutorial on Go Mutexes## Updating Articles Endpoint

The final endpoint you will need to implement is the Update endpoint. This endpoint will be a HTTP PUT based endpoint and will need to take in an Id path parameter, the same way we have done for our HTTP DELETE endpoint, as well as a JSON request body.

This JSON in the body of the incoming HTTP PUT request will contain the newer version of the article that we want to update.


Try create an updateArticle function and corresponding route in the handleRequests function. This will match to PUT requests. Once you have this, implement the updateArticle function so that it parses the HTTP request body, using the same code that you used in your createNewArticle function.

Finally, you will have to loop over the articles in your Articles array and match and subsequently update the article.


This example represents a very simple RESTful API written using Go. In a real project, we’d typically tie this up with a database so that we were returning real values.

PyTumblr lets you create all of the various types that Tumblr supports. When using these types there are a few defaults that are able to be used with any post type.

The default supported types are described below.

  • state - a string, the state of the post. Supported types are published, draft, queue, private
  • tags - a list, a list of strings that you want tagged on the post. eg: ["testing", "magic", "1"]
  • tweet - a string, the string of the customized tweet you want. eg: "Man I love my mega awesome post!"
  • date - a string, the customized GMT that you want
  • format - a string, the format that your post is in. Support types are html or markdown
  • slug - a string, the slug for the url of the post you want

We'll show examples throughout of these default examples while showcasing all the specific post types.

Creating a photo post

Creating a photo post supports a bunch of different options plus the described default options * caption - a string, the user supplied caption * link - a string, the "click-through" url for the photo * source - a string, the url for the photo you want to use (use this or the data parameter) * data - a list or string, a list of filepaths or a single file path for multipart file upload

#Creates a photo post using a source URL
client.create_photo(blogName, state="published", tags=["testing", "ok"],

#Creates a photo post using a local filepath
client.create_photo(blogName, state="queue", tags=["testing", "ok"],
                    tweet="Woah this is an incredible sweet post [URL]",

#Creates a photoset post using several local filepaths
client.create_photo(blogName, state="draft", tags=["jb is cool"], format="markdown",
                    data=["/Users/johnb/path/to/my/image.jpg", "/Users/johnb/Pictures/kittens.jpg"],
                    caption="## Mega sweet kittens")

Creating a text post

Creating a text post supports the same options as default and just a two other parameters * title - a string, the optional title for the post. Supports markdown or html * body - a string, the body of the of the post. Supports markdown or html

#Creating a text post
client.create_text(blogName, state="published", slug="testing-text-posts", title="Testing", body="testing1 2 3 4")

Creating a quote post

Creating a quote post supports the same options as default and two other parameter * quote - a string, the full text of the qote. Supports markdown or html * source - a string, the cited source. HTML supported

#Creating a quote post
client.create_quote(blogName, state="queue", quote="I am the Walrus", source="Ringo")

Creating a link post

  • title - a string, the title of post that you want. Supports HTML entities.
  • url - a string, the url that you want to create a link post for.
  • description - a string, the desciption of the link that you have
#Create a link post
client.create_link(blogName, title="I like to search things, you should too.", url="https://duckduckgo.com",
                   description="Search is pretty cool when a duck does it.")

Creating a chat post

Creating a chat post supports the same options as default and two other parameters * title - a string, the title of the chat post * conversation - a string, the text of the conversation/chat, with diablog labels (no html)

#Create a chat post
chat = """John: Testing can be fun!
Renee: Testing is tedious and so are you.
John: Aw.
client.create_chat(blogName, title="Renee just doesn't understand.", conversation=chat, tags=["renee", "testing"])

Creating an audio post

Creating an audio post allows for all default options and a has 3 other parameters. The only thing to keep in mind while dealing with audio posts is to make sure that you use the external_url parameter or data. You cannot use both at the same time. * caption - a string, the caption for your post * external_url - a string, the url of the site that hosts the audio file * data - a string, the filepath of the audio file you want to upload to Tumblr

#Creating an audio file
client.create_audio(blogName, caption="Rock out.", data="/Users/johnb/Music/my/new/sweet/album.mp3")

#lets use soundcloud!
client.create_audio(blogName, caption="Mega rock out.", external_url="https://soundcloud.com/skrillex/sets/recess")

Creating a video post

Creating a video post allows for all default options and has three other options. Like the other post types, it has some restrictions. You cannot use the embed and data parameters at the same time. * caption - a string, the caption for your post * embed - a string, the HTML embed code for the video * data - a string, the path of the file you want to upload

#Creating an upload from YouTube
client.create_video(blogName, caption="Jon Snow. Mega ridiculous sword.",

#Creating a video post from local file
client.create_video(blogName, caption="testing", data="/Users/johnb/testing/ok/blah.mov")

Editing a post

Updating a post requires you knowing what type a post you're updating. You'll be able to supply to the post any of the options given above for updates.

client.edit_post(blogName, id=post_id, type="text", title="Updated")
client.edit_post(blogName, id=post_id, type="photo", data="/Users/johnb/mega/awesome.jpg")

Reblogging a Post

Reblogging a post just requires knowing the post id and the reblog key, which is supplied in the JSON of any post object.

client.reblog(blogName, id=125356, reblog_key="reblog_key")

Deleting a post

Deleting just requires that you own the post and have the post id

client.delete_post(blogName, 123456) # Deletes your post :(

A note on tags: When passing tags, as params, please pass them as a list (not a comma-separated string):

client.create_text(blogName, tags=['hello', 'world'], ...)

Getting notes for a post

In order to get the notes for a post, you need to have the post id and the blog that it is on.

data = client.notes(blogName, id='123456')

The results include a timestamp you can use to make future calls.

data = client.notes(blogName, id='123456', before_timestamp=data["_links"]["next"]["query_params"]["before_timestamp"])

Tagged Methods

# get posts with a given tag
client.tagged(tag, **params)

Using the interactive console

This client comes with a nice interactive console to run you through the OAuth process, grab your tokens (and store them for future use).

You'll need pyyaml installed to run it, but then it's just:

$ python interactive-console.py

and away you go! Tokens are stored in ~/.tumblr and are also shared by other Tumblr API clients like the Ruby client.

Running tests

The tests (and coverage reports) are run with nose, like this:

python setup.py test

What is REST API? An Overview | Liquid Web

What is REST?

The REST acronym is defined as a “REpresentational State Transfer” and is designed to take advantage of existing HTTP protocols when used for Web APIs. It is very flexible in that it is not tied to resources or methods and has the ability to handle different calls and data formats. Because REST API is not constrained to an XML format like SOAP, it can return multiple other formats depending on what is needed. If a service adheres to this style, it is considered a “RESTful” application. REST allows components to access and manage functions within another application.

REST was initially defined in a dissertation by Roy Fielding’s twenty years ago. He proposed these standards as an alternative to SOAP (The Simple Object Access Protocol is a simple standard for accessing objects and exchanging structured messages within a distributed computing environment). REST (or RESTful) defines the general rules used to regulate the interactions between web apps utilizing the HTTP protocol for CRUD (create, retrieve, update, delete) operations.

What is an API?

An API (or Application Programming Interface) provides a method of interaction between two systems.

What is a RESTful API?

A RESTful API (or application program interface) uses HTTP requests to GET, PUT, POST, and DELETE data following the REST standards. This allows two pieces of software to communicate with each other. In essence, REST API is a set of remote calls using standard methods to return data in a specific format.

The systems that interact in this manner can be very different. Each app may use a unique programming language, operating system, database, etc. So, how do we create a system that can easily communicate and understand other apps?? This is where the Rest API is used as an interaction system.

When using a RESTful API, we should determine in advance what resources we want to expose to the outside world. Typically, the RESTful API service is implemented, keeping the following ideas in mind:

  • Format: There should be no restrictions on the data exchange format
  • Implementation: REST is based entirely on HTTP
  • Service Definition: Because REST is very flexible, API can be modified to ensure the application understands the request/response format.
  • The RESTful API focuses on resources and how efficiently you perform operations with it using HTTP.

The features of the REST API design style state:

  • Each entity must have a unique identifier.
  • Standard methods should be used to read and modify data.
  • It should provide support for different types of resources.
  • The interactions should be stateless.

For REST to fit this model, we must adhere to the following rules:

  • Client-Server Architecture: The interface is separate from the server-side data repository. This affords flexibility and the development of components independently of each other.
  • Detachment: The client connections are not stored on the server between requests.
  • Cacheability: It must be explicitly stated whether the client can store responses.
  • Multi-level: The API should work whether it interacts directly with a server or through an additional layer, like a load balancer.

I’ve been working with Restful APIs for some time now and one thing that I love to do is to talk about APIs.

So, today I will show you how to build an API using the API-First approach and Design First with OpenAPI Specification.

First thing first, if you don’t know what’s an API-First approach means, it would be nice you stop reading this and check the blog post that I wrote to the Farfetchs blog where I explain everything that you need to know to start an API using API-First.

Preparing the ground

Before you get your hands dirty, let’s prepare the ground and understand the use case that will be developed.


If you desire to reproduce the examples that will be shown here, you will need some of those items below.

  • NodeJS
  • OpenAPI Specification
  • Text Editor (I’ll use VSCode)
  • Command Line

Use Case

To keep easy to understand, let’s use the Todo List App, it is a very common concept beyond the software development community.
