Stuck on a problem and need help troubleshooting a recurring issue with the Workforce Engagement Management API. We are attempting to automate bulk shift swaps for our APAC BYOC trunk management team using the WFM REST API v1. The process works fine for small batches, but when processing more than 50 agents simultaneously, we consistently receive a 409 Conflict response.
The error payload indicates a scheduling rule violation, specifically referencing rule_id: SR_APAC_OVERRIDE_01. This is confusing because we have explicitly disabled these override rules in the Admin console for this specific group. The request targets the /api/v2/wfm/users/{userId}/shifts endpoint.
We are operating in the Asia/Singapore timezone (Asia/Singapore), and the conflict seems to trigger when the proposed shift overlaps with existing BYOC carrier maintenance windows defined in our custom rules. Has anyone encountered similar locking issues with bulk operations?
I have reviewed the WFM API documentation but it does not clarify the precedence of custom rules during bulk updates. Any insights on how to bypass or debug this specific conflict would be appreciated.
