How do we send access token Rest API request using OAuth through Postman?

[Aneesh Munnam]

I created access-token using steps from: https://developer.atlassian.com/cloud/jira/platform/jira-rest-api-oauth-authentication/. I am trying to make get Issue rest call through postman using the access-token generated. I tried in multiple ways:

1. Using Authorization OAuth 1.0 configuration.

When making this request I get oauth_problem=signature_method_rejected response.

2. Using access-token as Header:

When making this request I get 403 Forbidden issue. Is there any other way in handling this? Even trying to add it as param also results in same issue.
I am trying to attach this to my Spring Application using Spring Security. Can't we make postman requests with OAuthn generated Access-token?

The issue is with signature_method. the signature_method needs to be RSA-SHA1 which is not currently supported with Postman.
