About PSD2

Third Party Providers (TPPs) are able to connect to Juni’s dedicated API interface for providing aggregation and other relevant services to customers. Within the documentation, TPPs can find the access details for using the testing facility (Sandbox) and production API.


Sandbox is a secure, dedicated testing environment that facilitates the onboarding and learning process of the TPP with non-real user data. TPPs can find the testing facility’s access details (sandbox) and proceed with TPP onboarding by clicking on these links Juni EU and Juni UK.

Production API

After integrating the Sandbox to perform tests, TPP can use the production API configuration to go live. The documentation is available by accessing the Juni EU developer portal.
