Report a message, user, or channel

Users can report suspicious or harassing messages and other users who use abusive language in a channel. They can also report the channel itself if there is any inappropriate content or activity in the channel. Based on this functionality and our Report API, you can build your own in-app system for managing objectionable content and subject.

Dart

// Report a channel.
// channel below can be openChannel or groupChannel.
try {
  await channel.report(
    category: REPORT_CATEGORY,
    description: 'DESCRIPTION',
  );
} catch (e) {
  // Handle error.
}

// Report a message in a channel. 
// channel below can be openChannel or groupChannel.
try {
  await channel.reportMessage(
    message: MESSAGE_TO_REPORT,
    category: REPORT_CATEGORY,
    description: 'DESCRIPTION',
  );
} catch (e) {
  // Handle error.
}

// Report a user in a channel.
// channel below can be openChannel or groupChannel.
try {
  await channel.reportUser(
    userId: 'OFFENDING_USER_ID',
    category: REPORT_CATEGORY,
    description: 'DESCRIPTION',
  );
} catch (e) {
  // Handle error.
}
