63005: Channel rejected content. See Channel-specific error for details
MESSAGING
ERROR
This error occurs when a messaging channel rejects your outbound content after Twilio accepts the request. Review the channel-specific error returned on the failed Message resource or in your StatusCallback request to identify the exact reason for the rejection.
- The channel rejected the body, media, or other content in your outbound message.
- For WhatsApp, the recipient is not a valid WhatsApp user.
- For WhatsApp media messages, the media file is invalid, unsupported, too large, or otherwise does not meet WhatsApp media requirements. Silent MP4 files without an audio track can also fail on WhatsApp.
- For WhatsApp, you sent content that is not allowed for the current session type. Out-of-session sends require approved templates for supported content types.
- For WhatsApp media templates, the approved template header type does not match the media you sent.
- Your business or the recipient's WhatsApp number is in a country or region where WhatsApp business messaging is restricted or unsupported.
- Check
ChannelStatusMessageon the failed Message resource or in yourStatusCallbackwebhook, then correct the channel-specific rejection reason before retrying. - Verify that the recipient can receive messages on the selected channel. For WhatsApp, confirm that the
Tonumber belongs to an active WhatsApp user and is not in a blocked country or region. - Validate each media file before sending. Use a supported MIME type, keep the file within WhatsApp size limits, host it at a publicly accessible URL, and send only one media object in a free-form WhatsApp message.
- If an MP4 fails on WhatsApp, re-encode it with H.264 video and an AAC audio track, even if the audio track is silent. (help.twilio.com)
- Follow WhatsApp session and template rules. If you are outside the 24-hour customer service window, send an approved template. If you use an approved media template, send the same media header type that was approved.
- Review whether your business category and target country are eligible for WhatsApp messaging. If they are restricted, use a supported channel for that market. (help.twilio.com)
