--- ### Curl Best Practices * **HTTP Methods:** For `GET` requests, specifying `-X GET` is optional (as GET is the default action). However, `POST`, `PUT`, and `DELETE` must explicitly define the request method. * **Request JSON Header:** If sending a JSON payload via `-d`, you must also include the `-H "Content-Type: application/json"` header so the API endpoint parses the payload correctly. * **Secure API Tokens:** Never commit curl commands containing active Bearer API tokens to your Git repository history logs.
