Block and unblock other users

A user can register other users within an application. Users can instantly start 1-to-1 group chat and invite other users to existing group channels. On the other hand, a user can block specific users to stop receiving further messages from them in 1-to-1 or 1-to-N group channels. You can choose whether users can view which users they have blocked in the channel UI.

For blocking a user, you can set an option to include or exclude blocked users when sending invitations.It determines whether to automatically exclude blocked users when inviting users to a new group channel. The value of this option can only be changed from the Sendbird side before integrating your Sendbird application to the client app. If you want to change the value, contact our sales team for further assistance. (Default: including)

You can allow users to block and unblock other users by implementing the following code to your client app.

SBDMain::BlockUser(USER, [](SBDUser* blocked_user, SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }

    // The blocked user can be retrieved through the blocked_user parameter of the handler callback function.
});

SBDMain::UnblockUser(USER, [](SBDError* error) {
    if (error != nullptr) {
        // Handle error.
        return;
    }

    // The user is successfully unblocked.
});
