Test credentials

Everything you need to test in the sandbox: customer login credentials and a ready-to-run Postman collection.

Sandbox credentials

Use these credentials to log in as the customer (PSU) during sandbox authorisation.

No sandbox credentials are published for this client.

Postman collection

The fastest way to explore the API is the Postman collection. It signs every request for you — the environment file already provides dummy test certificates, so no certificate setup is needed in the sandbox.

Postman collection

Preconfigured, signed requests for the consent, account, and payment flows.

Postman environment

Set up in four steps

Import both files into Postman (File → Import).
Select the imported environment. It ships with dummy test certificates (TPP_PRIVATE_KEY, TPP_SIGN_CERT), so request signing works out of the box.
Run the jsrsasign.lib Install request once (folder First Use Install) to load the signing library.
Send requests. Request IDs, signatures, and the consentId are generated and chained automatically.
