Pega and Whatsapp Integration

 Pega and Whatsapp Integration

Following the procedure from Official Whatsapp Cloud API

1. Set up Developer Assets and Platform Access

The WhatsApp Cloud API and WhatsApp Business Management API are part of Meta’s Graph API, so you need to set up a Meta developer account and a Meta developer app. To set that up:

• Register as a Meta Developer 
• Enable two-factor authentication for your account 
• Create a Meta App: Go to developers.facebook.com > My Apps > Create App. Select the "Business" type and follow the prompts on your screen.

Click the app you want to connect to WhatsApp from the App Dashboard. Click Set up when you locate the "WhatsApp" product by scrolling down.

Following that, you will have the choice to choose an existing Business Manager (if you have one) or, if you prefer, have one created for you automatically through the onboarding process (you can customize your business later, if needed). Make your choice, then press Continue.

The following activities are carried out by the onboarding process when you click Continue:

The Business Manager that you selected or that was generated automatically is linked to your App.

You install a WhatsApp test phone number for your company. Without signing up or transferring a phone number, you can use this test number to explore the WhatsApp Business Platform.

- In your App dashboard click on "Getting started" under Whatsapp and note down your temporary access token ( Note : It's valid for 24hours only we need a business account to get permanent access token) Let's continue with this for now

Make sure to add the recipient's phone number's for a free account upto 5 recipient numbers are possible (this is basically the "toPhoneNumber" that you can use later, if any other number not mentioned in this list is given in our pega app it throws error
