Analytics API 403 During JMeter Load Test

My configuration keeps failing when hitting /api/v2/analytics/interactions/summary with 10 concurrent threads in JMeter 5.6. The US1 environment returns 403 Forbidden instead of data. The token is valid for single requests. Is there a specific rate limit for this endpoint under load? Checking Genesys Docs for limits, but nothing clear on concurrent access patterns for analytics queries.
