Outbound Campaign Dialer dropping calls after 403 Forbidden on /api/v2/outbound/campaigns endpoint

Struggling to figure out why our predictive outbound campaign is experiencing a 403 Forbidden error when attempting to update campaign status via the Genesys Cloud API. We are using the Python SDK version 3.12.4 and the issue manifests specifically when the campaign transitions from ‘PAUSED’ to ‘RUNNING’. The error response body indicates ‘Insufficient permissions for resource: campaigns/12345’, yet the OAuth2 token used has the ‘outbound:campaign:write’ scope explicitly granted. This behavior started after migrating three BYOC trunks from the US-East region to APAC-Singapore, which aligns with our regional failover strategy. The SIP registration status for these trunks shows as ‘Registered’ with no latency spikes, and outbound routing rules are correctly mapped to the new carrier. We have verified that the user credentials associated with the API client have not changed and that the campaign is not locked by another process. The logs show successful authentication but immediate rejection at the resource level. Is there a known restriction on cross-region campaign updates or a specific configuration in the outbound dialer settings that enforces region-locking for write operations? We need to ensure our automated scripts can manage campaigns across different geographic regions without manual intervention.

Check the OAuth token’s client_id against the AppFoundry app permissions. The outbound:campaign:write scope is correct, but if the app isn’t explicitly granted Campaign Admin rights in the Genesys Cloud admin console, the 403 persists. Verify the integration user has the Outbound Campaign Manager role.

It’s worth reviewing at the data action configuration instead of just the API permissions. The 403 often stems from the integration user lacking specific rights to modify campaign state via automated workflows.

Check if the user has the ‘Outbound Campaign Manager’ role assigned in the admin console. This role is required for bulk updates, not just individual API calls.

Make sure you verify the exact role assignment.

  • Confirm the integration user has the ‘Outbound Campaign Manager’ role, not just the API scope.
  • Check AppFoundry permissions for explicit Campaign Admin rights.

The 403 usually hides behind missing Admin Console roles, not just API scopes.

Insufficient permissions for resource: campaigns/12345

Assign the Outbound Campaign Manager role to the integration user and verify AppFoundry has explicit Campaign Admin rights. This fixes the permission gap immediately.
