Why is this setting causing immediate 429 responses when hitting the Quality Management API endpoints during a simulated WFM schedule synchronization?
Running a load test to validate API throughput for a new WFM integration. The scenario involves fetching and updating agent schedule metadata via the platform_api. Using JMeter 5.6.2 with a thread group set to ramp up 200 users over 60 seconds. The target endpoint is /api/v2/wfcm/schedules.
The issue is not WebSocket limits. It is strictly REST API rate limiting. The logs show a sudden spike in 429 Too Many Requests errors after the first 50 requests. The response headers include Retry-After: 2. This is unexpected. The documentation suggests a higher baseline limit for standard GET operations.
“Standard API rate limits are applied per organization. For WFM-related endpoints, the limit is typically 100 requests per minute per user context. Bulk operations may require specific scopes.”
The test uses valid OAuth tokens with the wfm:schedule:view scope. Each thread simulates a unique agent context. The latency before the 429 is low (<50ms). This indicates the server processes the request but rejects it due to quota exhaustion.
Is there a way to increase the rate limit for WFM schedule endpoints? Or is there a recommended batching strategy for high-concurrency schedule syncs? The current approach fails to simulate realistic peak loads. The goal is to ensure the integration handles 500 concurrent agents during shift changes.
Config details:
- JMeter: 5.6.2
- GC Version: 2024-05
- Scope:
wfm:schedule:view,quality:assessment:read - Endpoint:
/api/v2/wfcm/schedules
The error pattern is consistent. Every 101st request fails. Need to understand if this is a hard limit or if there is a configuration override. Also, checking if the Retry-After header can be parsed dynamically in JMeter to implement backoff. Any insights on optimizing the request pattern for WFM data syncs?
