Hosted onboarding API
Click to copy

This API is used for the classic integration. If you are just starting your implementation, refer to our new integration guide instead.

The Hosted onboarding API provides endpoints that you can use to generate links to Adyen-hosted pages, such as an onboarding page or a PCI compliance questionnaire. You can provide these links to your account holders so that they can complete their onboarding.


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:

-H "Content-Type: application/json" \

Alternatively, you can use the username and password to connect to the API using basic authentication. For example:

-H "Content-Type: application/json" \

When going live, you need to generate new web service user credentials to access the live endpoints.


The Hosted onboarding API supports versioning using a version suffix in the endpoint URL. This suffix has the following format: "vXX", where XX is the version number.

For example:
Get a link to a Adyen-hosted onboarding page
Get a link to a PCI compliance questionnaire
