Introduction ​

Treezor provides Open Banking services on behalf of Treezor's clients (financial institutions, payment service providers, or regulated entities). As a client, your primary responsibility is to authenticate your end users (PSUs) when Third Party Providers (TPP) request access to their account data.

What is a Treezor Client? ​

Treezor's clients:

  • Hold a payment institution or electronic money institution license
  • Use Treezor's Open Banking platform to provide AISP services
  • Manage PSU authentication for OAuth2 authorization flows
  • Operate under their own brand while leveraging Treezor's technical infrastructure
