I encountered an error while attempting to send a WhatsApp template message via the WhatsApp Business API, and I would appreciate guidance on resolving it. Below are the details:
Error Description
[400] [310000] (313000B) Required parameters in missing business Button at index 1 of type copy_code; returned as non-empty parameter coupon_code.
Issue Summary
- The API expects a button parameter of type
copy_codeat index 1, but the request containscoupon_codeinstead. - This mismatch is causing the template message to fail with a 400 Bad Request error.
Steps I’ve Taken
- Verified the template structure in WhatsApp Business Manager.
- Checked the API request parameters for consistency with the template.
Request for Help
Could someone assist me with:
- Correctly structuring the API request to match the template’s expected parameters?
- Clarifying whether I should modify the template approval or the API payload?
- Any best practices to avoid similar issues in the future?
Thank you in advance for your support!
