Standing Orders

As per the OBIE API standards for Standing orders, and in line with our direct channels, our APIs offer the opportunities for customers to choose the number of payments or the last payment date they would like when setting up a Standing Order via a Payment Initiation Service Provider. The latest date for a final payment is 31st December 2059. If customers require a long term standing order then this can be achieved by selecting a high number of payments or a last payment date that keeps the standing order in place till 31st December 2059 at the latest. In coming months we will add an option of ‘until further notice’ for a standing order as an additional way to set up long term standing orders up to 31st December 2059.

App 2 App Information

Prerequisites for testing

TPPs must have :
• An existing production integration with the Brand that the TPPs wish to test App2App against
• Bank Accounts for the Brand they wish to test – must have credentials for e-Banking/Online Banking/Personal customer (Bankline customers currently not supported)
• Bank’s Mobile App can be downloaded from iOS and Android app stores

Integration

There are new Authorization Servers (AS’s) for App2App; these will be added to the OBIE Directory post testing period
Each Authorization Server hosts a .well-known endpoint (the only difference though is the AS’s URL “authorization_endpoint”)
NatWest Mobile Banking :
- Authorization Server : https://personal.secure1.natwest.com/as/authorization.oauth2
- Well-Known Endpoint : https://personal.secure1.natwest.com/.well-known/openid-configuration

N.B. “Please note that only values in the OIDC request object will be processed and responded to. Any additional values or checks will be ignored. RBS will update this page once this is resolved for PKCE checks.”
