Sending Webhooks in Go

Dec 10, 2022

Webhooks are a powerful tool for automating tasks and integrating applications. In a nutshell, a webhook is a way for one application to provide real-time information to another application by making a HTTP request to a specified URL. In this article, we'll look at how to send webhooks in Go.

Programming webhooks

First, let's define a few terms that are commonly used when discussing webhooks:

  • The sender is the application that sends the webhook.
  • The receiver is the application that receives the webhook.
  • The event is the action that triggers the webhook. For example, when a user signs up for a service, an event is triggered and a webhook is sent.

To send a webhook in Go, we'll need to use the

library. This library provides a convenient way to make HTTP requests in Go.

Here is an example of how to send a webhook in Go:

package main

import (

type WebhookData struct {
    Event string `json:"event"`
    UserID int `json:"user_id"`

func main() {
    webhookURL := "https://www.example.com/webhook"

    data := WebhookData{
        Event: "user_signed_up",
        UserID: 12345,

    jsonData, err := json.Marshal(data)
    if err != nil {

    resp, err := http.Post(webhookURL, "application/json", bytes.NewBuffer(jsonData))
    if err != nil {
    defer resp.Body.Close()

In the code above, we first define a

struct that represents the data we want to send in the webhook. This struct has two fields:

Next, we define the main function where the webhook will be sent. We first define the URL of the webhook receiver as a variable called


We then create an instance of the

struct and populate its fields with the appropriate data. In this case, we're sending information about a
event and the
of the user who signed up.

Next, we use the

function to convert the
struct into a JSON string. This is necessary because webhooks are typically sent as JSON data.

Finally, we use the

method to make a POST request to the webhook receiver. We pass in the webhookURL, the
header, and the JSON data as arguments to the method. This will send the webhook to the receiver.

That's all there is to it! With just a few lines of code, you can easily send webhooks in Go. This can be a powerful tool for integrating applications and automating tasks.
