Welcome to the "Connection Endpoints (Legacy)" section of the Trulioo API Reference. This section covers the legacy connection endpoints used to establish and manage your integration with Trulioo’s services. These endpoints were designed to facilitate communication and authentication with Trulioo's APIs, including methods for verifying connection status and managing your API keys. Key features include the ability to check the connection status with Trulioo’s "SayHello" endpoint, which helps you ensure your integration is responsive and properly set up. Additionally, you’ll find information on the legacy authentication process, as well as troubleshooting common connection issues. Although these endpoints are now considered legacy, they are still important for users maintaining older integrations. This section will guide you through the use of these legacy connection methods and help you transition to newer APIs if needed.
