### Handling Bounce Actions Programmatically

Source: https://getstream.io/moderation/docs/guides/bounce-message

This section details how to programmatically handle bounce actions when not using a UI SDK. It explains how to detect bounce actions from API responses and guide users through the correction process.

```APIDOC
## Handling Bounce Actions Programmatically

If you are not utilizing a UI SDK, you can programmatically handle bounce responses using the **send message response API**. Bounce actions are indicated in the `moderation` object, which is part of the `message` object in the API response.

### API Response Example for Bounce Action

```json
{
  "message": {
    "type": "error",
    "text": "The message original text",
    "user_id": "user_id",
    "moderation": {
      "action": "bounce",
      "original_text": "The message original text"
    }
  }
}
```

### Steps to Handle Bounce Programmatically:

1.  **Detect the Bounce Action**:
    *   Check the `action` field within the `moderation` object in the API response.
    *   If the `action` field is set to `bounce`, the message has been returned to the sender for correction.

2.  **Return Feedback to the User**:
    *   Extract the `original_text` field from the `moderation` object to display the message to the user.
    *   Provide clear guidance on why the message was bounced and how to correct it.

    **Example UI prompt:**
    > "Your message could not be sent because it violates our content guidelines. Please adjust your message and try again."

3.  **Handle Resubmitted Messages**:
    *   When the user edits and resubmits, send the updated text back to the API for moderation.
    *   If the follow-up message passes moderation, it will be delivered successfully.
    *   If the follow-up message still violates guidelines, additional actions, such as **flag** or **block**, will be triggered based on your configured moderation rules.
```
