# Mark WhatsApp Channel post as paid partnership

This is useful for sponsored posts, influencer campaigns, brand collaborations, and any Channel content that should be clearly marked as commercial.

### Before you start

You need:

* An authorized [Whapi.Cloud channel](/help-desk/getting-started/welcome-to-whapi.cloud.md);
* A valid API token;
* The WhatsApp Channel ID in the `@newsletter` format;
* The Message ID of the [Channel post](/help-desk/channels/send-post-to-whatsapp-channel-newsletter.md) you want to mark.

Example Channel ID: `120363298746512907@newsletter`

In order to find out the identifier use the following method: [GET /newsletters](https://whapi.readme.io/reference/getnewsletters)

### Add the Paid Partnership label

{% embed url="<https://whapi.readme.io/reference/addnewslettermessagepaidpartnership>" %}

Use: `POST https://gate.whapi.cloud/newsletters/{NewsletterID}/messages/{MessageID}/paid_partnership`

Replace:

* `{NewsletterID}` with the WhatsApp Channel ID;
* `{MessageID}` with the ID of the Channel post.

#### Example request

```bash
curl -X POST "https://gate.whapi.cloud/newsletters/120363298746512907@newsletter/messages/H7nK4pQ2vD9mX6aL3sT8wB1cR5yF0jE/paid_partnership" \
  -H "Authorization: Bearer <CHANNEL_TOKEN>" \
  -H "accept: application/json"
```

### Result

After a successful request, WhatsApp marks the post as a paid partnership.

In the message data, this state is shown in the `context` object:

```json
{
  "context": {
    "paid_partnership": true
  }
}
```

You can check the updated message state using the message retrieval methods or by processing webhook updates.

### Important notes

* The method works with WhatsApp Channel posts only.
* The `NewsletterID` must end with `@newsletter`.
* Use the original Message ID returned when the Channel post was created.
* The label is displayed by WhatsApp as a native Paid Partnership marker.
* The label cannot be removed once added.&#x20;
