Message Block Notification Callback

By default, the sender of a message is unaware if the message has been intercepted by RC's content moderation service. If your app wishes to notify the sender when a message is blocked due to triggering moderation rules, you can enable the Blocked Message Status Callback to Sender service.

RC's content moderation service (including message sensitive words, IM moderation service, and message callback service) may intercept messages under the following circumstances:

• The content of a text message triggers RC's built-in sensitive words, preventing the message from being delivered to the recipient.
• The content of a text message triggers your custom sensitive words (blocked words), preventing the message from being delivered to the recipient.
• The message triggers the moderation rules set by the IM Moderation service or the Message Callback Service, preventing the message from being delivered to the recipient.

Enabling the Service

You can enable the Blocked Message Status Callback to Sender feature by navigating to the RC Console, then going to Configuration > Chat settings > Basic features > Security.

Setting Up the Sensitive Words Interception Listener

You can set up a sensitive words interception listener using the onMessageBlocked method to monitor intercepted messages and the reasons for interception.
