### MangoApps OpenAPI Usage Basics
When integrating with MangoApps using the OpenAPI set, adhere to the following guidelines:
* **Authentication Session**:
* Upon successful login via the Login API, you will receive a `_felix_session_id` in the Set-Cookie field of the response header.
* Your application must store this `_felix_session_id` securely for use in subsequent API requests.
* All subsequent API requests must include the `_felix_session_id` as a cookie in the header.
* The session remains valid until explicitly terminated by calling the Logout API.
* **Using cURL Examples**:
* In cURL examples, a file is often used to store the `_felix_session_id`. You can define this file name as needed during your testing.
* **API URLs**:
* Always use your own MangoApps domain URI followed by the appropriate API path and parameters.
* Do not use `mangoapis.mangoapps.com` as shown in examples; replace this with your domain-specific URI.
By following these steps and guidelines, administrators can successfully register, manage, and utilize custom applications integrated with their MangoApps domain.
