    The read receipts feature allows you to see how many messages remain unread for a specific member. You can also use the feature to mark all unread messages of a specific member as read.

    Note: This feature is only applicable to group channels.

    The following table shows a list of actions supported for read receipt. API endpoints are relative to the base URL allocated to your Sendbird application. In this page, the /{channel_type}/{channel_url}/messages endpoint refers to https://api-{application_id}.sendbird.com/v3/{channel_type}/{channel_url}/messages.

    Note: If you want to know the ID and base URL of your application, sign in to the Sendbird Dashboard, go to the Settings > Application > General, and then check the Application ID and API request URL.

    • It's recommended that the parameter values in API URLs be urlencoded, such as {user_id} and {channel_url}.
