API is not working in POSTMAN

[Devansh1]

Hi all, 

we are trying to hi the api for our third-party website we have created record in Application Registry and a integration user with required roles, now the problem is when we are hitting tha api it is generating an error. 

(attached SS).

And the main thing is when we are trying to do with our another instance it is working fine. 

we have almost tried everything, what could be problem ......

@Devansh1 

so are you consuming OAuth endpoint?

since you are trying from postman and it worked for 1 instance and not for other, did you compare the roles etc?

Also check ACL on OAuth profile table and oauth_credential table

Non-admin users cannot retrieve OAuth token from OAuth Credentials table to make outbound REST call

We are sending this api with the method of 'POST' . it is working fine for the others instance only getting error in our instance. 

 so we have made the user and application registry in both the instances and tested for which we want to hit the api. 

Could be problem from SN side??
