What is a Third Party Provider (TPP)?

Third Party Providers (known as TPPs) are Payment Service Providers (PSPs) that may use APIs to access your accounts with your permission.

To make use of these TPP services, you will need to give your permission to the TPP. A TPP cannot access your account without your permission.

AISPs and PISPs are types of TPP.
