WFM Scheduling API 409 Conflict on Bulk Shift Assignment via AppFoundry

How do I correctly to handle concurrent shift assignment updates when using the WFM scheduling API from a multi-tenant AppFoundry application?

The integration currently processes bulk shift assignments for large agent groups using POST /api/v2/wfm/scheduling/schedule-elements. When executing requests for overlapping time windows across multiple organizations, the platform returns a 409 Conflict error with the message: “The schedule element was modified by another user or process.”

The application implements standard exponential backoff, but the conflict rate remains high during peak scheduling hours. This suggests that the client-side locking mechanism is insufficient for the scale of operations. The OAuth tokens possess full wfm:scheduling:write permissions, and the request headers include the correct X-Genesys-Organization-ID.

Is there a recommended pattern for optimistic locking or batch processing that minimizes these conflicts? The current retry logic is causing significant latency in the provisioning workflow, which impacts the user experience for our enterprise clients. Any insights on handling these race conditions at scale would be appreciated.
