Running into a stubborn issue with the WFM scheduling API. Trying to automate the weekly schedule publish via a custom script hitting POST /api/v2/wfm/scheduling/schedules/{scheduleId}/publish. The payload is identical to what works in the UI, but the endpoint consistently returns a 400 Bad Request with errorCode: "SCHEDULE_INVALID" and message: "One or more shifts are invalid."
The schedule covers the standard Tuesday-to-Monday rotation for our Chicago team. All shifts have valid start/end times in CDT, and agent assignments are confirmed active in the roster. Checked the audit logs and nothing stands out as a configuration mismatch.
Is there a hidden validation rule in the API that differs from the UI? Specifically, does the API enforce stricter buffer rules or break compliance checks before the actual publish? We are using the latest Python SDK (v2.14.0) for authentication.
Need to get this automated before the Monday morning shift swap deadline. Any insights on how to debug the specific shift causing the rejection without manually iterating through 50 agents?
The SCHEDULE_INVALID error on the publish endpoint is rarely about the shift times themselves. It’s almost always a schema validation issue with the shifts array structure in the JSON body. The UI handles hidden fields and default values, but the API is strict.
If you are generating this payload dynamically, check for two common pitfalls in the shifts object:
Missing shiftId: Even for new shifts, the API often expects a unique identifier or a specific structure that matches the draft. If you are copying from the UI export, ensure the id field is present for each shift object.
Timezone Format: Ensure startTime and endTime are in ISO 8601 format with the correct offset (e.g., 2023-10-24T08:00:00+08:00 for Singapore time). A missing Z or incorrect offset triggers a 400 immediately.
Here is a minimal valid structure for a single shift. Notice the explicit type and name fields:
Also, verify that the userId exists and is active. If the user is deactivated or missing, the schedule is invalid.
If you are running this in a load test context, remember that the WFM API has lower throughput limits than the routing API. If you are hitting this endpoint concurrently for multiple schedules, you might hit rate limits before validation errors. Add a 500ms delay between requests in your JMeter thread group to isolate validation errors from 429s. Check the x-request-id header in the response logs to correlate specific failures.
