WEM Bulk Import 429 Error During Load Test

Genesys Cloud WFM

My configuration keeps failing… Running JMeter against /api/v2/wem/schedules with 200 concurrent threads. Getting 429 Too Many Requests immediately after 50 calls. Using v2.0 API. Is there a specific header to increase burst allowance for bulk schedule imports? Need to hit 500 concurrent users for peak validation. Current script uses basic auth. Any tips on staggering requests without failing the load test scenario?

Have you tried reducing the concurrency? The WEM endpoint enforces strict tenant-level rate limits that cannot be bypassed via headers. Staggering requests is mandatory for bulk imports.

Make sure you check your tenant’s specific rate limit tier before ramping up concurrency, as WEM APIs often have stricter caps than general platform endpoints.

{
 "retry_after": "{{header.Retry-After}}",
 "exponential_backoff": true
}

Ignoring the 429 response headers will just get your IP temporarily blocked by the gateway.
