Health Check
All environments expose the same health check endpoint:AWS PrivateLink Connection
For secure, private connectivity from your AWS VPC for the FIX API, use AWS PrivateLink. This routes traffic over AWSβs private network instead of the public internet. VPC Service Names and PrivateLink endpoints are provisioned per-firm during FIX onboarding. Contact onboarding@polymarket.us with your AWS Account ID to get started.Environment Progression
We recommend the following integration progression:- Dev - Initial development and unit testing
- Preprod - Integration testing and pre-launch validation
- Prod - Live trading
Contact onboarding@polymarket.us to request access credentials for each environment.
