AppFoundry Web Messaging Widget 401 on Token Refresh in Multi-Tenant Setup

Could use a hand troubleshooting this persistent authentication failure within a custom AppFoundry integration. The application utilizes the Genesys Cloud Web Messaging widget (genesyscloud-webmessaging-jssdk v1.2.4) to embed support capabilities directly into our partner’s CRM interface. The initial handshake and user identification via identifyUser succeed without issue, establishing a valid session for the first 59 minutes.

However, immediately upon the expiration of the access token, the widget attempts to refresh the credentials using the stored refresh token. Instead of receiving a new access token, the backend returns a 401 Unauthorized response with the error code AUTHENTICATION_FAILED. This occurs exclusively in our multi-org deployment scenarios where the integration relies on the offline_access scope for persistent state. Standard single-org deployments function correctly.

The environment details are as follows: Genesys Cloud API v2, Node.js runtime v18.17.0, and the integration is hosted on AWS Lambda. The refresh logic mirrors the standard OAuth 2.0 flow documented for platform APIs. Has anyone encountered scope limitations or specific token caching requirements for the Web Messaging SDK that differ from standard REST API authentication? The logs indicate the refresh token itself is valid, suggesting a potential issue with how the widget context handles the token exchange in a cross-tenant environment.

This looks like a token synchronization issue rather than a pure authentication failure. The Web Messaging SDK manages its own token lifecycle, but in a multi-tenant AppFoundry context, the parent application often handles the refresh logic. If the widget attempts to refresh using a stale or misaligned access token, the 401 occurs.

POST /api/v2/authorization/token/refresh 401 Unauthorized

Check if the onTokenRefresh event handler in your custom integration is correctly passing the new token to the widget instance. The standard approach involves listening for the event and updating the widget configuration dynamically.

webMessaging.onTokenRefresh((token) => {
 widget.setAccessToken(token);
});

Ensure the refresh token scope includes webchat:read. Also, verify that the AppFoundry iframe communication is not blocking the postMessage events required for token handoff. This is a common gap when embedding digital channels in third-party CRMs.
