Error Message | Explanation |
User's number is part of an experiment :: Failed to send message because this user's phone number is part of an experiment | The recipient's number is currently part of a Meta-led experiment, during which certain types of WhatsApp messages may be blocked or restricted. This is controlled by Meta and beyond Zixflow’s control. You may try sending the message later or ask the user to initiate the conversation. |
(#2) Service temporarily unavailable :: Server is temporarily unavailable. Please retry after some time. | This means Meta’s server is temporarily down or facing issues. It’s not related to Zixflow or your configuration. Wait for some time and retry sending the message. The issue usually resolves automatically. |
Message undeliverable :: Message Undeliverable. | The message could not be delivered to the recipient’s WhatsApp account. Possible reasons include the user no longer being on WhatsApp, the number being inactive, blocked, or restricted by Meta to maintain platform health. It’s not an issue with Zixflow or the template. |
This message was not delivered to maintain healthy ecosystem engagement. :: In order to maintain a healthy ecosystem engagement, the message failed to be delivered. | Meta has blocked this message to protect the quality of user experience and avoid excessive or unsolicited messaging. This typically occurs if the recipient has not engaged recently or if message frequency is too high. It's a safeguard controlled by Meta, not an issue with Zixflow or the template. Try sending the message later or after the user initiates a conversation. |
WhatsApp provided number needs display name approval before message can be sent. | This means the phone number you've added to WhatsApp Business API has not yet received approval for its display name from Meta. Messages cannot be sent using that number until the display name is reviewed and approved. Please ensure the display name has been submitted via the WhatsApp Manager in Meta Business Suite, and wait for approval to complete. |
Business eligibility payment issue | This error indicates that there's a problem with the business verification or payment status required to use WhatsApp Business API. It may be related to pending verification, payment issues, or account setup not meeting Meta’s eligibility criteria. Please contact Zixflow Support at support@zixflow.com so we can help resolve the issue directly with Meta. |
Re-engagement message | This refers to messages sent outside the 24-hour customer service window on WhatsApp. To re-engage users after 24 hours of their last message, businesses must use a pre-approved template message. If you're seeing issues, ensure you're using an approved template and the message complies with Meta's policies. If problems persist, contact Zixflow Support at support@zixflow.com for assistance. |
