• Go to Postman 
• Under "Authorization" tab, selected "OAuth 2.0" as the "Type". 
• Token Name: "XYZ Test"
• Grant Type: Authorization Code

• Callback URL: https://www.getpostman.com/oauth2/callback
• Auth URL: https://ims-na1.adobelogin.com/ims/authorize/v1
• Access Token URL: https://ims-na1.adobelogin.com/ims/token/v1
• Client ID: Entered the Client ID as generated 
• Client Secret: Entered the Client Secret as generated.
• Scope: openid AdobeID read_organizations additional_info.projectedProductContext additional_info.job_function

• Client Authentication: Send client credentials in body
• Click "Request Token".
