The Adyen API provides endpoints you connect to using your web service user credentials. These endpoints represent specific actions like making payment requests, modifying payments states, making payouts, and so on.
To perform a certain action you must post a request to the corresponding endpoint and handle the response. Adyen supports JSON, SOAP, and FORM (HTTP POST) communication types.
This API Reference section lists all available endpoints, as well as data types used in requests and responses.
