There is no anonymous/self-service registration path — client credentials are provisioned to appointed brokers and producers through AIG, not through a developer portal signup. schemes: - name: OAuth2 / OpenID Connect (Okta) type: oauth2 protocol: OpenID Connect 1.0 issuer: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7 authorization_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/authorize token_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/token userinfo_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/userinfo jwks_uri: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/keys introspection_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/introspect revocation_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/revoke end_session_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/logout device_authorization_endpoint: https://auth1.customerpltfm.aig.com/oauth2/aus1aaqj1zvwVDL2n5d7/v1/device/authorize registration_endpoint: https://auth1.customerpltfm.aig.com/oauth2/v1/clients grant_types: - authorization_code - implicit - refresh_token - password - client_credentials - urn:ietf:params:oauth:grant-type:device_code - urn:openid:params:grant-type:ciba token_endpoint_auth_methods: - client_secret_basic - client_secret_post - client_secret_jwt - private_key_jwt - none pkce: supported: true code_challenge_methods: - S256 id_token_signing_alg: RS256 id_token_encryption_alg: - RSA-OAEP-256 - RSA-OAEP-384 - RSA-OAEP-512 claims: - ver - jti - iss - aud - iat - exp - cid - uid - scp - sub scopes_ref: scopes/aig-scopes.yml source: well-known/aig-oauth-authorization-server.json - name: OpenID Connect (AIG Okta org issuer) type: openIdConnect issuer: https://auth1.customerpltfm.aig.com openid_configuration: https://auth1.customerpltfm.aig.com/.well-known/openid-configuration scopes: - openid - email - profile - address - phone - offline_access - groups source: well-known/aig-openid-configuration.json - name: Bearer token at the API gateway type: http scheme: bearer applies_to: https://commercial.api.aig.com evidence: >- GET https://commercial.api.aig.com/pmp-gateway/c2a/pmp-ext-gtw-api returned HTTP 400 {"error":"Protect Proxy via okta Service Policy: The message does not contain the Authorization header"} — the gateway names Okta as the policy enforcement point and an Authorization header as the required credential. mfa: enforced: true evidence: >- https://www.aig.com/mfa-authentication is a published page in AIG's sitemap and the Producer Management Portal embeds the Okta Sign-In Widget with MFA/OTP grant types advertised by the authorization server. onboarding: self_service: false note: >- No public signup or sandbox key issuance was found.
