The API reference itself is gated behind tenant authentication. summary: types: - oauth2 schemes: - name: oauth2ClientCredentials type: oauth2 flow: clientCredentials scheme: bearer description: >- CONFIRMED: Sirion B2B APIs use the OAuth 2.0 client credentials grant. A tenant administrator generates an OAuth Client Id and OAuth Client Secret under Admin 2.0 -> Business API & Integrations (OAuth Client Setup, added in release 2.84 with token permission configuration), and shares them with the integration. The client exchanges them for an access token that is presented as a Bearer token on API requests. MODELED: the exact token URL is tenant-specific and not publicly documented; substitute your tenant's token endpoint. sources: - https://www.sirion.ai/integrations/ - https://www.sirion.ai/library/whats-new/sirion-release-284/ - https://www.sirion.ai/library/whats-new/sirion-release-286/ notes: >- Access is enterprise / contract-gated. OAuth client credentials are provisioned per tenant; there is no public self-service key issuance. maintainers: - FN: Kin Lane email: kin@apievangelist.com
