Developer Tab Overview

Click the Developer tab on your application’s detail page. This tab contains three main sections:

API Keys — Manage API keys for accessing your application
Webhook — Configure an endpoint to receive real-time WhatsApp events
Send Test Message — Send test messages to registered test numbers

API Keys

In the API Keys section, you can view, copy, and create new API keys for your application. Each row contains the following information:

Column	Description
Name	The name given to the key (e.g. `Default Production Key`).
Created	The date and time the key was created.
Expires	The key’s expiration period. `Never` means it never expires.
Key	The masked key value. Can be copied or revealed using the icons next to it.

Creating a New API Key

Click the + Create API Key button in the top right corner.

In the modal that opens:

Field	Description
Key Name	A name to identify the key (e.g. `production Server`). Required.
Expires	The key’s expiration period: `6 Months`, `1 Year`, `2 Years`, `5 Years`, `Never`, or `Custom`.

After entering the information, click Create API Key.

Important: The key can only be viewed in full at the moment it is created. Don’t forget to save it somewhere secure.

Webhook

In the Webhook section, you configure an endpoint to receive real-time events from WhatsApp (messages, status updates, etc.). There are three tabs: Configuration, Subscribed Events, and Simulate incoming webhook.

Configuration

Field	Description
Webhook Callback URL	The URL where WhatsApp events will be POSTed. It must be publicly accessible and able to respond to GET requests.
Save Configuration	Used to save URL changes.
Test Webhook	Sends a test request to the saved URL to verify the connection.
Headers	Custom headers to be added to webhook requests. Use + Add Header to add a new row, and the trash icon to delete.

After entering the URL, first click Save Configuration, then verify the connection with Test Webhook.

Subscribed Events

In this tab, you select which WhatsApp events will be sent to your webhook.

Event	Description
messages	Incoming messages.
message_status	Message status updates (sent, delivered, read).
message_template_status	Template status changes (approved, rejected).
read	Read receipt events.
account	Account-level events.

Check the boxes next to the events you want and click Save.

Simulate Incoming Webhook

Use this tab to test your webhook endpoint without waiting for a real WhatsApp message.

Field	Description
Target URL	The URL the test payload will be sent to (same as the URL in Configuration).
Preset	Select the payload type to send (e.g. `Incoming text message`).
Payload	The JSON payload automatically generated based on the selected preset.
Send payload	POSTs the test payload to the selected URL.

Send Test Message

This panel lets you send test messages to registered test numbers. There are two modes: Custom Message and Template Message.

Adding a Test Number

First, you need to register the number you want to use as a recipient. Click the + Add Test Number button in the top right corner.

Enter your phone number and click Send code. A 6-digit verification code is sent to that number via WhatsApp.

Enter the code in the relevant fields and click Verify. Once verified, the number is saved as a test number.

The code is valid for 2 minutes. If it expires, use Resend code to request a new one.

Custom Message

24-Hour Rule Reminder: Non-template messages (text, media, etc.) can only be sent within 24 hours of the user’s last message.

Field	Description
Recipient	Select one of the previously added test numbers.
Message	The message text you want to send. Maximum 4096 characters.

Fill in the fields and click Send Test Message.

Template Message

Field	Description
Recipient	Select one of the previously added test numbers.
Template	Select one of your approved templates from the dropdown list.

Make your selections and click Send Test Message.
