The content you are trying to send was rejected by the Channel. Please see Channel specific error message for more information.

When sending messages to an end user on WhatsApp, this error may occur when the end user is not a valid WhatsApp user.

When sending messages with media to an end user on WhatsApp, this error may occur when WhatsApp detects an issue with the media file sent.

[August 14, 2025] To avoid these errors urls can be utilized in call to action url buttons. Variables sent in CTA url fields require the website domain to be static but the path can be variable. New templates will need to be created to use these features. Alternatively urls can be sent in text within a 24 hour conversation window. CTA url buttons can be used with card (https://www.twilio.com/docs/content/twiliocard) and call-to-action templates (https://www.twilio.com/docs/content/twilio-call-to-action).

Make sure the end user you are messaging has a valid WhatsApp account.

Make sure the media file sent is valid. Try to download the media file being sent. Export the file to a different valid format and re-upload it to your storage solution. If sending over WhatsApp, resubmit a new template for approval with the new media file.

Confirm that you are sending rich content within the sending session guidelines. If fields that are only supported as part of a template or fields that are only available in session are sent incorrectly, this error may occur.
