# Api Keys

### How do I get an API key?

The API key is a **unique identifier that is assigned to you**. This allows you to track usage and activities such as purchases and sales count made through your integration. To get an API key please kindly [Fill out this form](https://paychant.com/contact) and one of our team will reach back to you in a few moments with the next steps. In case you need additional support or inquiry, please contact us at [sales@paychant.com](http://sales@paychant.com).

### Adding an API key in your integration

The parameter name for the API key is partnerApiKey, its value type is a string, and it should be passed along with other parameters.
