Connect your own WhatsApp Business phone number to Cal ID so workflow reminders and confirmations are sent to attendees from your official business account.
Connecting WhatsApp Business to Cal ID lets your workflow reminders and confirmations reach attendees from your own official business number instead of the default Cal ID number. This page is the hub for the full integration; the steps below walk you through installing the app, choosing your number, and attaching it to a workflow.
Select the business portfolio associated with your WhatsApp Business account, then pick the WhatsApp Business account (the number) you want to use.
Your address and Tax ID must be verified on Meta to trigger the templates.
Picking the account behind your number

5
Set up the workflow
After you click Confirm, your WhatsApp Business app is installed and connected to your Cal ID account.Next, go to Cal ID and choose the event type where you want the workflow. Select your WhatsApp Business phone number, choose the template from the Message Template dropdown, and save the workflow.
Attaching your number to a workflow
If you don’t have a template yet, click Create Template in the Message Template dropdown and create one. Meta reviews every template, so allow time for approval before you rely on it.
