# How to Mark Messages as Read

When receiving a message, advance the seen sequence to mark it as read and clear the notification.

```
PUT /v4/channel/{channel_id}/seen-seq/{seen_seq}?force=false
```

Use the `conversation_id` and `conversation_sequence` from the webhook Message payload.

The `force` query parameter is required. Pass `false` to only advance the seen sequence forward. Pass `true` to force it even if `seen_seq` is lower than the current value.
