Sending Webhooks in Go
Dec 10, 2022Webhooks 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.

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
net/http
Here is an example of how to send a webhook in Go:
package main import ( "bytes" "encoding/json" "net/http" ) 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 { panic(err) } resp, err := http.Post(webhookURL, "application/json", bytes.NewBuffer(jsonData)) if err != nil { panic(err) } defer resp.Body.Close() }
In the code above, we first define a
WebhookData
Event
UserID
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
webhookURL
We then create an instance of the
WebhookData
user_signed_up
user_id
Next, we use the
json.Marshal()
WebhookData
Finally, we use the
http.Post()

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.
