Data Action 429 Error During JMeter Load Test

I’m completely stumped as to why the Data Action returns 429 Too Many Requests when simulating 200 concurrent calls.

Environment: Genesys Cloud US1
Tool: JMeter 5.6

request:
 method: POST
 url: /api/v2/integrations/data/actions
 headers:
 Content-Type: application/json
 Authorization: Bearer {{token}}

The error starts after 5 seconds. Need help with rate limits.
