API Access

Polymarket US provides API access for participants and technology partners. API access requires an application process and integration testing to ensure compliance and security. To apply for API access, contact our support team to begin the application process. Our team will review your application and assess technical and regulatory requirements. Upon qualification, you'll complete integration testing in our sandbox environment to ensure proper functionality. After successful testing and approval, you'll receive production API credentials.
