# Reverse integration: messaging

The Smartico platform can notify your system whenever it sends an asset (such as an email, SMS, or push notification) to a user via HTTP call.

\
For example, Smartico can trigger an HTTP request (typically a POST) to your API each time an asset is sent. This enables you to track user communications in real time.\
Possible Parameters Included in the Request

* **Time** – Timestamp in epoch milliseconds
* **Campaign Name** – The name of the campaign that triggered the asset
* **Asset Type** – Communication channel (e.g., Email, SMS, Push)
* **External User ID** – The user ID in your system
* **View URL** – A link to view the content of the sent asset

This setup is handled by the Smartico team based on the information you provide. You’ll need to share:

* **HTTP URL** of your API endpoint
* **Preferred HTTP method** – POST is recommended, but GET is also supported
* **Content type** – "application/json" is suggested
* **Body template** – For POST requests, a JSON payload structure must be defined

**Example of setup**

> Note: The following is a sample request body. It is fully configurable and can be adapted to match your existing API. In 99% of cases, we can integrate with your current structure without requiring changes on your end.

* URL - <https://mysite.com/users/communications>
* Method POST
* Content-Type: "application/json"
* Body template

```json
{
  "login": "123123",
  "time": 1664115803000,
  "view_url": "<URL which shows the content of the asset>",
  "channel": "SMS",
  "campaign_name": "RND Flow"
}
```

If you already have an API that handles similar notifications, in most of the cases we can reuse it with minimal to no modification.<br>
