How to get your WhatsApp Business credentials:

Before you can authenticate and use the WhatsApp Business API, you need to create an application on Meta for Developers. Follow these steps to set up your app:

Developer Account:

Ensure you have a developer account on Meta for Developers. If you don’t have one, sign up at Meta for Developers.

Accessing Meta for Developers App Dashboard:

Create App:

On the App Dashboard, locate and click on “Create App” to initiate the app creation process.

Next, you’ll need to choose an app type. Choose Business.

After completing the previous steps, you’ll need to provide a clear and memorable display name for users to identify your app. If you have a Facebook Business account relevant to your app, you can link it for easier management. Otherwise, the platform creates a test account for you to experiment with Facebook’s features. Once you’ve made your selections, simply click “Create App” to move forward.

Then, you’ll need to add products to your app. Scroll down until you see WhatsApp and click the Set up button:

And with that, your app is created and ready to use. You’re automatically directed to the app’s dashboard.

Creating a Permanent Access Token

Go to Business Settings.
Select the business account your app is associated with.
Below Users, click System Users.
Click Add.
Name the system user, choose Admin as the user role, and click Create System User.
Select the whatsapp_business_messaging permission.
