The Polymarket Exchange API is available in two environments. Use the appropriate endpoints based on your integration stage.

​
Endpoints

The Audience value for each environment matches its REST API base URL.

​
API Path Patterns

​
Authentication

Cache the access token and reuse it until close to expiry. expires_in is 86400 seconds (24 hours) in every environment. Keep one cache per process, shared across threads. Do not request a new token per API call.

​
Health Check

All environments expose the same health check endpoint:
VPC connections are required only for FIX API access. REST and gRPC APIs use the public endpoints listed above and do not require VPC setup.
For secure, private connectivity from your AWS VPC for the FIX API, use AWS PrivateLink. This routes traffic over AWS’s private network instead of the public internet. VPC Service Names and PrivateLink endpoints are provisioned per-firm during FIX onboarding. Send your AWS Account ID to your Polymarket contact to get started.

​
Environment Progression

We recommend the following integration progression:
  1. Preprod - Integration testing and pre-launch validation
  2. Prod - Live trading
Ask your Polymarket contact for access credentials for each environment.
