Creating Dummy Credentials, Fetching Dummy Accounts Data, Fetching Dummy Transaction Data

Our objective was to create dummy credentials successfully(without 401 error code) and try to pull some dummy accounts, transaction data to store in our database. This will enable us to test our entire data pipeline. But when we are trying to access /credentials endpoint with Post method using some dummy credentials, we are not able to create credentials successfully. Is there any possibility for us to get some dummy accounts, transactions data from playbook ?

Yes, of course, the credentials needed for Sandbox Environment are this:

All the test credentials for any bank to test integration and view actual data are username: " test" password : “test” except SAT sandbox rfc: "ACM010101ABC " password: “test” .
