## How PayPI (beta) works?

![API request flow](/files/-Mai2V4MbU0DoHNOGT5h)

PayPI works as an authentication hub for your API, we manage creating and managing API keys, onboarding, payments etc. You just have to pass the users Subscriber Secret to us via our API, and we let you know if you can allow the request. Once your request is allowed you can charge the user for the request using [Charges](/api/charges.md).
