This unit covers the admin functionality behind WhatsApp messages. By the end of it, you’ll be able to set your users up to use it in Fastcall. End-user training is found here.
Enable WhatsApp for your org
First, you have to open a support case with Fastcall saying that you want to enable WhatsApp for your org. You must have a Facebook Business Manager account. If you don’t already have a Facebook Business Manager account, you must create one at business.facebook.com.
If you already have a Facebook Business Manager account, follow these steps to find the ID:
- Access the Business Settings page on Facebook Business Manager.
- Click Business Info.
- Your ID will be listed under “Business Information.”
Fastcall will need this ID to enable WhatsApp for your org.
Enable phone numbers with WhatsApp capability
This functionality must be enabled per provisioned phone number. Go to Fastcall Settings > Admin Settings > Phone Numbers > Manage Phone Numbers and check the Whatsapp Enabled button in the Messaging Settings section for each number.

Outbound messages
You may only initiate conversations using an approved Message Template. Any Message Template must comply with WhatsApp terms and policies, and only be used for its designated purpose. WhatsApp has the right to review, approve, and reject any Message Template at any time.
To have a Message Template approved, you have to contact Fastcall Support.
You may reply to a user message without the use of a Message Template as long as it’s within 24 hours of the last user message. Conversations initiated by users open once the first business reply message is delivered. Outside the 24-hour customer service window, you may only send messages via approved Message Templates.
For more information on WhatsApp for business see here.
You should also review the business messenger policy including best-practices for opt-in.
If you have any doubts, problems, or errors, please contact Fastcall Support.
