Data Action API 429s during JMeter load test on US1

No idea why this is happening, POST /api/v2/integrations/datapipelines triggers immediate 429 Too Many Requests errors when concurrent throughput exceeds 10 requests per second. Environment: Genesys Cloud US1. Tool: JMeter 5.6. Threads: 20 concurrent. Endpoint: POST /api/v2/integrations/datapipelines. Error: 429 Too Many Requests. Running JMeter 5.6 with 20 concurrent threads against the Data Actions endpoint to validate integration pipeline creation throughput for a new automation batch process. Getting immediate 429 errors when trying to validate capacity for bulk pipeline updates. The Retry-After header returns 60 seconds, which seems excessive for a configuration API. Is there a specific rate limit for Data Actions in US1? Previous tests on Message API and Screen Pop showed similar 429 behavior, but those have documented limits. Data Actions documentation is vague on throughput caps. Need to know if this is a hard limit or if we can request an increase for our load testing phase. Any insights on the exact rate limit for POST /api/v2/integrations/datapipelines would be helpful. Currently blocked on validating our integration scaling strategy due to these rapid 429 responses.
