You can send messages with the trial period experience.
Using a trial period before business verification with the embedded signup
Before your business is verified, you can start testing the experience with a trial period. The following are the main limitations of the trial period:
30-day trial period.
If within the 30-day trial period and the business verification or WhatsApp checks are rejected, the trial ends.
The maximum number of WhatsApp accounts under one business is two.
Only valid for the first verified phone number for each WhatsApp Business Account.
For information on the trial period, see Unverified Trial Experience in the Facebook developer documentation.
Performing Facebook business verification for the embedded signup
A Facebook business verification confirms that a Business Manager account belongs to an actual business or organization. Facebook may ask you to complete a business verification process. A WhatsApp Business Account (WABA) is required to complete the process. For more information on business verification, see About Business Verification. For the step to perform verification, see Verify your Business in Business Manager.
