WFM Schedule Publish API 409 Conflict with Pending Shift Trades

Can anyone clarify the exact behavior of the /api/v2/wfm/schedules POST endpoint when agents have active shift trade requests? We are using the Genesys Cloud Python SDK (v15.2.0) to automate weekly schedule publications for our Chicago-based team. The process usually runs smoothly, but recently we started hitting HTTP 409 Conflict errors specifically when agents have pending swap approvals in the system. The error payload indicates a version mismatch, but it seems tied to the state of the shift trade rather than a simple document revision issue. We need the schedule to publish with the current accepted trades, but the API rejects the entire batch if any trade is in a ‘pending’ state.

This is disrupting our weekly workflow significantly since we publish schedules every Monday morning. We want to ensure that only approved swaps are reflected, but the API seems to lock the schedule object entirely. Is there a specific query parameter or a pre-publish step we are missing to resolve these conflicts? We have tried filtering agents with pending trades, but that leaves gaps in coverage. Looking for a programmatic way to handle this without manual intervention in the WFM UI.

If you check the docs, they mention that version conflicts during schedule publication are often caused by concurrent modifications to the underlying schedule object. When shift trades are pending, the WFM engine may lock specific schedule segments, causing the SDK’s default publish mechanism to fail if it does not explicitly handle optimistic concurrency control.

This HCL snippet demonstrates how to configure the schedule resource to handle versioning correctly during automated updates. By setting version to null or using the API’s force parameter where available, you can bypass stale version errors.

resource "genesyscloud_wfm_schedule" "weekly_schedule" {
 name = "Chicago Weekly Schedule"
 schedule_type = "WEEKLY"
 
 # Ensure version is handled dynamically to avoid 409s
 version = null 
}

Always verify the schedule ID matches the one returned by the GET endpoint before calling POST. Using the CLI to fetch the latest version number first is a reliable workaround if the SDK does not support automatic version bumping in the current release.
