openbanking/conformance-dcr repository overview

The Dynamic Client Registration Conformance Tool is an Open Source test tool provided by Open Banking⁠.

The Dynamic Client Registration⁠ APIs allow TPPs to register one or more clients with ASPSPs in a manner that offers very low friction and removes hurdles and barriers to entry. The goal of the DCR Conformance Tool is to allow implementers of DCR to test an interface against the DCR standard.

The supporting documentation assumes technical understanding of the Open Banking ecosystem and DCR. An introduction to the concepts is available via the Open Banking Website⁠.
