## 1. Subscribing to an API

Subscribing to an API that uses PayPI for payments is easy, just follow their PayPI share URL, and follow the instructions to get a [Subscription Secret](/subscriptions.md#subscription-secret) you can use with the API.

## 2. Using an API

You will find your [Subscription Secret](/subscriptions.md#api-secret) on the Subscriptions page, follow the documentation from the API provider to see how to use this in requests.
