# HTTP API

### Using the HTTP API

The FoxMetrics server-side HTTP API can be used to send data from any system to FoxMetrics by making a GET or POST request to your account collector host with the event details you want to send. 

> The call must be made using the HTTPS protocol. 

{% hint style="info" %}
Your collector host and application identifiers can be found in the [portal](https://my.foxmetrics.com) after you log in.
{% endhint %}

| Name | Type   | Description                                                                         |
| ---- | ------ | ----------------------------------------------------------------------------------- |
| v    | String | Person ID. A unique identifier that identifies the device that performed the event. |
