A WhatsApp app is what connects your WhatsApp business number to your webhook (the main element of the experience: this is where you receive, process and send messages. ) and is where you configure various settings for the WhatsApp experience.

In this guide, you'll learn how to set up a WhatsApp app.

• Facebook Developer Account: Your developer account is needed to create new apps, which are the centerpiece of any WhatsApp integration. You can create a new developer account by logging into the Facebook https://developers.facebook.com/ developer website and clicking the "Get Started" button.

• Facebook Business Account: Meta Business Manager is a tool that helps you organise and manage your business. You can create your business manager by following this guide Create your Business Manager

• Facebook app: The Facebook app contains settings for your Whatsapp experience. To create a new app, visit the app dashboard by clicking "My Apps" in the top bar of the developer page.

• Webhook URL: Actions that take place in conversations, such as new messages, are sent as events to your webhook.  Along with the callback url, a verification token will be provided that will need to be used when installing the app. CTLiveSocial needs to be reachable via a public WebHook according the following format

To create a Facebook app, from the Facebook developer page (https://developers.facebook.com/ ), click on "My Apps" and then on the "Create an app" button.
