OBIE publishes version 3.1.7 of the TPP MI Specification


The Open Banking Implementation Entity (OBIE) has published version 3.1.7 of the TPP MI Specification – a new addition to the Open Banking Standard. It enables Third Party Providers (TPPs) participating in the OBIE ecosystem to report Management Information (MI) data, regarding their usage of OBIE’s API specifications.

Financial institutions that qualify as Account Servicing Payment Service Providers (ASPSPs) already submit detailed MI reporting data. This enables OBIE to measure usage of open banking APIs, monitor adoption and take necessary actions as appropriate.

This version 3.1.7 update enables TPPs to submit MI reporting data as well. Benefits to the ecosystem and OBIE include more complete perspectives into adoption and business value, as well as the reconciliation of ecosystem data when combined with ASPSP MI reporting data.

That reconciliation will enable OBIE to:

  1. Understand the success and take-up of open banking
  2. Assess the performance of the API services from TPPs’ perspectives
  3. Measure drop-out rates for each group of services
  4. Forecast volumes and user growth, to allow for support service and capacity planning
  5. Understand usage patterns for potential future product development

The following artefacts have been developed to provide the full set of benefits and to support the provision of MI:

Enrolled ecosystem participants are encouraged to contact their IES Team representatives with any questions or queries regarding the version 3.1.7. update.
