Vanquis Bank Dynamic Client Registration API
Vanquis Bank's OpenID / OBIE Dynamic Client Registration (DCR) endpoint, documented on the Vanquis developer portal, allowing onboarded Third Party Providers to register OAuth clients programmatically using OBIE/eIDAS certificates as part of the Open Banking Directory enrolment flow. The production host is provisioned per TPP during onboarding and is not publicly published; no Vanquis-proprietary OpenAPI is published for this surface.
