Vanquis Bank Account and Transaction API (AIS) is one of 4 APIs that [Vanquis Banking Group](https://apis.io/providers/vanquis-banking-group/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Account Information, AISP, and Open Banking. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

Vanquis Bank's OBIE Read/Write Account and Transaction Information API (AISP), conformant to the Open Banking Implementation Entity Read/Write Data API Standard v3.1.10. Enables authorised Account Information Service Providers to access account, balance and transaction data with customer consent, secured under the PSD2 / FAPI profile (OAuth2/OIDC, mutual-TLS, SCA). The production host is provisioned to each TPP during Open Banking Directory onboarding and is not publicly published; the harvested OpenAPI is the shared OBIE standard contract Vanquis conforms to, not a Vanquis-proprietary document.
