Quick question about... WFM API 429 on Schedule Data Export via ServiceNow

Quick question about… handling rate limits when pulling schedule data from Genesys Cloud WFM to ServiceNow.

We are implementing a nightly sync job using a ServiceNow Data Action to pull agent schedules via the /api/v2/wfm/schedules/{scheduleId} endpoint. The goal is to populate a custom CMDB table with shift details for reporting purposes. The integration works flawlessly for small teams, but as we scale to the full organization (approx. 500 agents), the request starts failing intermittently with HTTP 429 Too Many Requests.

I have reviewed the documentation on rate limiting and implemented a basic retry logic with exponential backoff in the ServiceNow script include. However, the 429 errors persist even with a 5-second delay between requests. The response headers indicate X-Rate-Limit-Remaining is being respected, but the limit seems to reset slower than expected when querying nested resources like scheduleEntries.

Status: 429 Too Many Requests
Headers:
 X-Rate-Limit-Limit: 1000
 X-Rate-Limit-Remaining: 0
 X-Rate-Limit-Reset: 1678901234
 Retry-After: 60
Body:
 {
 "errors": [
 {
 "code": "RateLimitExceeded",
 "message": "Rate limit exceeded. Please retry after 60 seconds."
 }
 ]
 }

Is there a specific pagination strategy or bulk endpoint I am missing for WFM schedule data? The standard pagination parameters (page, pageSize) seem to have minimal effect on the rate limit consumption for this specific resource. We are currently using the latest version of the Genesys Cloud REST API client in ServiceNow. Any insights on optimizing this query pattern or alternative endpoints for bulk schedule retrieval would be appreciated. We need to ensure this sync completes within the 4-hour nightly maintenance window without triggering throttling.

I’d suggest checking out at batching requests instead of individual calls. The WFM API has strict rate limits. Use a Terraform module to define the export job configuration. This handles pagination and retries automatically. See the payload below for the correct structure.

{
 "scheduleId": "123",
 "exportFormat": "JSON",
 "batchSize": 50
}
