Well honestly it all depends on the application for the respective API. Purchasing this script and installing it is very easy, the tedious process is getting your application for the API approved.

Facebook Cloud API requires you to have a Facebook Business Page, a system administrator access to the account to create your permanent user access token. However Facebook Cloud API is better in sense of Message Templates and the GUI. You can add header/footer with buttons. If you already have a Facebook Account with a Facebook Business Page approved then using this API would be a better choice.

Twilio API is more easy to apply. Its almost instant. You wouldnt need a Facebook Business Page, or other tedious applications. However the GUI is slightly limited. You cant add buttons on twilio yet (at the time of writing, 18/04/2023).

Both API’s would require you to pre-write your message templates and submit for approval. Each template may take up to 24hours to get approved before you can start using it in the script.

When you apply for the API in the respective websites, you will be given a number by them. The number may not be fancy or uses the right country code. This may let your users into thinking its spam. You can always import your spare number into their system for free. Its usually instant. You may need to verify the number belongs to you before the import is successful, through OTP usually.

However, the number you’re importing must not have WhatsApp Already being used on it. If it does, you need to close the WhatsApp Account permanently before you import.
