Why it occurs
This error typically results from Meta blocking certain numbers, either directly or due to the use of specific message templates. These blocks are part of Meta’s compliance framework to ensure adherence to its messaging policies and standards.
Steps to resolve the issue
1. Test with another number
– Try sending the same message to a different destination number.
– If it succeeds, the original number may be blocked by Meta for policy or compliance reasons.
2. Examine template usage
– Review the message template used in the failed delivery.
– Ensure the template aligns with Meta’s content policies and does not contain restricted content.
3. Verify recipient’s status
– Confirm that the recipient’s number is active and capable of receiving WhatsApp messages.
– Check for any known issues or restrictions that may have been applied to that number.
4. Contact Support
If the issue persists after performing the above checks, contact our Support team at [email protected]. Include the following details to help expedite the investigation:
