FAPI Conformance 2 min read
Every TPP must obtain a Relying Party (RP) certification for their application against the CBUAE FAPI 2.0 Message Signing Profile before being promoted to production. This certification is issued by the OpenID Foundation (OIDF) and is an exit criterion from the API Hub Sandbox.
TPPs integrate as OAuth 2.0 clients — they consume the LFI's Authorization Server. The correct certification track is therefore the Relying Party (RP) test, not the Authorization Server (AS) test. Selecting the wrong track will produce results that are not accepted.
CBUAE FAPI 2.0 RP Message Signing ID1
TPPs must achieve the CBUAE FAPI 2.0 RP Message Signing ID1 certification. A public list of organisations that have already certified is available at:
https://openid.net/certification/certified-cbuae-fapi-2-0-rp-message-signing-id1/
Certification must be renewed for each major new version of the Standards.
Configure and run the OIDF test plan
1. Access the Conformance Suite
The OIDF conformance suite is available at www.certification.openid.net. Log in with a Google or GitLab account to create and run test plans.
2. Configure the Test Plan
When scheduling a new test, use the following configuration exactly:
| Setting | Value |
|---|---|
| Test Plan | FAPI2-Message-Signing-ID1: Relying Party (client) test |
| Sender Constraining | mtls |
| Client Authentication Type | private_key_jwt |
| Authorization Request Type | rar |
| Request Method | signed_non_repudiation |
| FAPI Client Type | oidc |
| FAPI Profile | cbuae |
| FAPI Response Mode | plain_response |

3. Note on Test Data Visibility
After running the conformance tests, all data used — including public and private keys of certificates and client data from the test — will be made available in the ecosystem and visible to other participants. If you run the certification in a production environment, you must revoke the certificates used during the tests and obtain any required customer consent. It is strongly recommended to use dedicated test certificates.
4. Submit for Certification
Once tests pass, submit your results to the OIDF for certification. Follow the submission instructions at:
Inform Nebras as soon as the OIDF issues your certification
TPPs must inform Nebras immediately upon receipt of their FAPI Certification from the OIDF. Receipt of certification is an exit criterion from the API Hub Sandbox — production promotion will not proceed until this has been confirmed.
Paid directly to the OIDF
Certification fees are fixed and paid directly to the OIDF. The current fee schedule is available at:
https://openid.net/certification/fees/
Fees are significantly reduced for OIDF members. Institutions that expect to certify multiple implementations or renew frequently may find OIDF membership cost-effective. Membership information and benefits:
