Error codes

Sendbird Chat SDKs for .NET and Unity have two types of error codes:

  • Client error codes: these errors are usually caused by something the client app side did, such as incorrect or invalid parameter, or sending a request when disconnected.
  • Server error codes: these errors are usually caused by a Sendbird server side issue.
