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. |
to make HTTP request to get access token by postman, please follow these steps:
Open Postman and create a new request by clicking on the "New" button in the top-left corner.
Select the HTTP method as "POST" from the dropdown menu next to the URL input field.
Go to the "Authorization" tab, from the "Type" dropdown menu, select "Basic Auth" since you are using the client ID and client secret for authentication..
In the "Username" field, enter your client ID, In the "Password" field, enter your client secret.
Key:
username, Value:<your_client_id>Key:
password, Value:<your_client_secret>

Add the following key-value pair in the body:
