Hi @nasarazaz13 ,
Couple of clarifications
1.Which version of API GW are you using?
2. Have you tried after clearing the cookies.
3. Can you change your callback url? It seems it is not working one
I tried on the cloud version of API GW with below config on my postman client and it works
Configuration done at postman client :
Auth Url: https://sagdevevangelist.apigw-aw-us.webmethods.io/invoke/pub.oauth/authorize
Call back URL: https://oauth.pstmn.io/v1/callback
Client ID: 4ece3eeb-354f-424c-94fc-********b30
Scope: MyScopeName
Configuration done on API GW application
Let me know if this helps.
Regards

but for all other grant types it worked.
