Agent Scripting API 429 Error During JMeter Load Test

Is it possible to configure higher rate limits for the Agent Scripting API when running automated load tests?

We are validating the system capacity for agent script assignments during peak hours. The environment is Genesys Cloud US1. We use JMeter 5.6 for simulation. The goal is to assign scripts to 500 concurrent agents within a 60-second window.

The issue appears when the script assignment requests exceed a certain threshold. The API returns 429 Too Many Requests. This happens even though the total daily limit has not been reached. We suspect a per-second or per-minute rate limit is being hit.

Here are the steps to reproduce the problem:

  1. Create a JMeter test plan with 500 threads.
  2. Configure a HTTP Request sampler to call POST /api/v2/agentscripting/scripts.
  3. Set the payload to assign a specific script ID to the agent user ID.
  4. Add a constant throughput timer to send 10 requests per second per thread.
  5. Run the test for 60 seconds.
  6. Observe the response codes in the View Results Tree listener.

The error response body contains:
{“errors”:[{“code”:“RATE_LIMIT_EXCEEDED”,“message”:“You have exceeded the rate limit for this API endpoint.”}]}

We have tried adding a random delay between requests. This reduces the error rate but does not eliminate it. The total execution time increases significantly. This is not acceptable for our load testing requirements.

We need to assign scripts quickly to simulate realistic agent login flows. The current rate limit seems too low for bulk operations. Is there a way to request a higher limit for our organization? Or is there a better API endpoint for bulk script assignments?

Please note that we are using the same API key for all requests. We have verified that the key has the correct permissions. The user role is Agent. The script status is Active.

Any advice on how to handle this rate limit would be appreciated. We are stuck on this step for our capacity planning project. The deadline is approaching soon.
