This guide provides step-by-step instructions on utilizing <client_id> and <client_secret> for secure authentication, ensuring the confidentiality of sensitive credentials.
Please when using Postman, exercise caution when entering your client ID and client secret. Make sure to clear any sensitive information from the request history or environment variables in Postman after use. Additionally, consider using Postman's built-in authorization mechanisms, such as the "Basic Auth" feature, and securely manage your Postman environment settings to prevent accidental exposure of your credentials.
