Account API

This API is used for the classic integration. If you are just starting your implementation, refer to our [new integration guide](https://docs.adyen.com/marketplaces-and-platforms) instead. The Account API provides endpoints for managing account-related entities on your platform. These related entities include account holders, accounts, bank accounts, shareholders, and verification-related documents. The management operations include actions such as creation, retrieval, updating, and deletion of them. For more information, refer to our [documentation](https://docs.adyen.com/marketplaces-and-platforms/classic). ## Authentication Your Adyen contact will provide your API credential and an API key. To connect to the API, add an `X-API-Key` header with the API key as the value, for example: ``` curl -H "Content-Type: application/json" \ -H "X-API-Key: YOUR_API_KEY" \ ... ``` Alternatively, you can use the username and password to connect to the API using basic authentication.
