What is the meaning of this error? How do I fix this in my chat sequence?


There may be a variety of reasons why you see this error message after trying to send a message in your sequence.

  • The user fails to provide consent to the message

  • User disabled the app

  • There's a technical issue on Facebook's side

  • The person blocked messages from your Page (that's why you are not able to contact them via a private message)

Please note that The 551 Error is the expected result for many privacy issues, such as if the User has not engaged with your page through one of the entry points documented, blocked your page, disable its account, among others. Messenger provides multiple ways for users to opt-out of getting messages. This is something that your Application needs to handle. This error code is referenced here and is not an issue with the platform but rather a feature.

I hope this unblocks you. We are always looking for ways to do better and I will really appreciate if you could share your feedback via our survey!
