I can’t seem to figure out why the OAuth authorization flow for our newly certified AppFoundry Premium App is consistently returning a 403 Forbidden error during the consent grant phase. The integration is designed to leverage Single Sign-On (SSO) for seamless user authentication across multiple Genesys Cloud organizations. We have configured the redirect URI correctly in the AppFoundry console and ensured that the application permissions align with the scope requested in the initial authorization request. Despite meticulous verification of the client credentials and the redirect URL whitelist, the platform rejects the consent request before the user is even presented with the permission dialog.
The specific error response indicates a mismatch in the expected audience or a validation failure within the SAML assertion processing, though no detailed error payload is returned in the HTTP response body. We are utilizing the standard Genesys Cloud OAuth 2.0 endpoints for the authorization code grant flow. The issue appears isolated to the initial handshake where the platform attempts to validate the SSO provider’s response against the registered application settings. This behavior is inconsistent with our previous deployments, which successfully completed the consent phase without any authentication hurdles.
Our development environment is running the latest version of the Genesys Cloud JavaScript SDK, and we have verified that the certificate used for SAML signing is valid and correctly uploaded to the Genesys Cloud admin console. The multi-tenant architecture of our application requires robust handling of different organization contexts, and this blockage prevents any user from accessing the integrated features. We have attempted to clear browser caches, use incognito windows, and test from different network locations, but the 403 response remains persistent across all test scenarios.
Is there a specific requirement for the SAML response format or a hidden configuration step in the AppFoundry security settings that we might be overlooking? We need to resolve this authentication bottleneck urgently as it halts the entire deployment timeline for our enterprise clients. Any insights into the internal validation logic for SSO-based OAuth flows in a multi-org context would be greatly appreciated.
