This article covers common TikTok Business Messaging errors that may occur during messaging or when connecting your TikTok Business Messaging channel to SleekFlow.
As TikTok may update their documentation regularly, we recommend referring to the official TikTok Business Messaging documentation for the most up-to-date information. SleekFlow reviews these updates and ensures users are guided to the latest resources when needed.

 

Error code is a numeric or alphanumeric code that indicates the nature of an error and, when possible, why it occurred. It helps you to identify the cause of a problem, a failing component, and the service actions that might be needed to solve the problem.
