Agent Scripting API 429s during JMeter load in ap-southeast-1

Need some help troubleshooting rate limiting issues when integrating the Agent Scripting API with our WFM scheduling logic. We are trying to dynamically update agent scripts based on real-time shift swap approvals, but the integration hits a wall during high-concurrency testing.

The environment is Genesys Cloud, region ap-southeast-1. We are using a custom Architect flow to trigger script updates via the REST API after a shift swap is validated. Under normal load, it works fine. However, during JMeter load tests simulating peak shift changeover (around 600 concurrent requests), we start seeing 429 Too Many Requests errors specifically on the POST /api/v2/scripts endpoint.

Here is the relevant configuration snippet from our load test script:

api_endpoint: "https://api.mypurecloud.com/api/v2/scripts"
headers:
 Authorization: "Bearer {{token}}"
 Content-Type: "application/json"
rate_limit_strategy: "fixed"
requests_per_second: 50
concurrency: 600

The error response includes a Retry-After header, but implementing exponential backoff in Architect seems to introduce too much latency for real-time adherence updates. Is there a specific rate limit threshold for script updates in this region, or should we be batching these requests differently? Any insights on optimizing this flow would be appreciated.

Oh, this is a known issue…

The rate limits for the Agent Scripting API are strict, especially in ap-southeast-1. You need to implement exponential backoff in your JMeter test plan. Add a BeanShell PreProcessor to check the Retry-After header on 429 responses and pause the thread accordingly. Also, ensure your Architect flow is batching requests rather than firing them individually for each shift swap.
