If you want to send a Refunds request, you must supply your confidential API key with /auth. Include your Global Commerce username and encoded password with the /auth. Global Commerce will authenticate the credentials.
Hint: When using a Postman collection, provide your Global Commerce credentials in the csrUserName and csrPassword fields.
For example, a Global Commerce user with the Customer Service Director, Customer Service Supervisor, or Customer Service Representative role can access the /auth service to get the access_token and then use that access_token to create a satisfaction refund.
