Postman is a GUI-based tool ideal for testing, debugging, and developing REST API calls. It supports HTTPS, headers, authentication, and structured JSON payloads, making it perfect for Check Point API validation.

jq '.[0]' selects the first element of the JSON array, which is useful when only one result is needed or when parsing data like a list of network objects.

Securing Gaia API involves using HTTPS with trusted certs and restricting access to specific client IPs. These measures reduce attack surface and ensure only authorized tools access the system.

The logout command is used to terminate an authenticated session and invalidate the session ID.
This is essential for security and freeing up session resources on the Management Server.

The Gaia API has a different structure (e.g., /gaia-api/v1) and also requires login via POST with credentials. Unlike the Management API, Gaia API focuses on OS-level configurations.
