Is it possible to programmatically approve a batch of pending shift swap requests using the WFM Scheduling API? Our team processes dozens of swaps weekly for the America/Chicago zone, and the manual click-through in the admin UI is becoming a bottleneck during peak publishing hours.
I have been reviewing the documentation for the /api/v2/wfm/schedules endpoints, but I only see methods for retrieving schedule details or publishing full schedules. There does not appear to be a direct endpoint for managing swap approvals in bulk.
I attempted to use the general scheduling update endpoint with a payload resembling the one below, hoping it might trigger an approval state change, but the response returns a 400 Bad Request error indicating invalid fields for the current operation. The error message specifically flags swap_request_id as an unexpected parameter.
Is there a workaround for this, or is a custom script using the UI automation the only viable path for now? We need this to integrate smoothly with our existing weekly publishing workflow.
Make sure you verify the exact endpoint structure before attempting bulk operations, as the WFM API does not natively support a single “approve all” call for shift swaps. The standard approach requires iterating through the pending requests. You can retrieve the list of pending swap requests using the GET /api/v2/wfm/schedules/swap-requests endpoint. Filter by status=pending and your specific schedule ID. For each request returned, you must issue an individual POST /api/v2/wfm/schedules/swap-requests/{swapRequestId}/approve call.
While this feels tedious, it ensures audit trail integrity. Do not attempt to parallelize these calls aggressively without rate-limiting, as the WFM engine can throttle high-frequency modification requests, leading to 429 Too Many Errors. I have seen scripts fail silently when they hit the concurrency limits of the scheduling service.
A more robust pattern involves batching the API calls in chunks of 5-10 with a 200ms delay between batches. This mimics human interaction patterns and reduces the likelihood of hitting backend locks. Also, ensure your service account has the WfmSchedulingAdmin role; standard viewer roles will return 403s even if the endpoint exists.
If you are processing dozens of swaps weekly, consider wrapping this logic in a scheduled task or a simple Node.js script that runs during off-peak hours (outside of your America/Chicago publishing window). This prevents contention with other scheduling operations. The key is to handle the response codes explicitly: a 200 confirms approval, while a 409 indicates a conflict, likely due to overlapping shifts or rule violations. Log these conflicts for manual review rather than retrying automatically, as they require human judgment. This method, while requiring more code than a single click, provides the scalability and auditability needed for large teams.
It’s worth reviewing at the bulk export API instead. The WFM API lacks a direct batch approval endpoint, so pulling the IDs via the swap-requests endpoint and processing them through a script is the standard workaround. This avoids the 429 errors from rapid individual calls.
Make sure you add delays between requests.
Cause: GC’s API gates are stricter than Zendesk’s ticket updates, so rapid batch calls trigger immediate 429 errors.
Solution: Implement a 200ms sleep in your loop to stay within rate limits.
