Answer 1

I got this issue initially while setting up Sitecore Commerce 9. Ensure your identity app pool user (for e.g. Server_Name\CSFndRuntimeUser) has been added & given permission to Identity Server client certificate (e.g. identity.server) under Certificate Manager (Certificates > Personal > Certificates). Hope it helps!

Please check the below configuration at postman side:

• SSL Certificate verification should be Off at your postman setting

You can refer the below blog to setup you postman:
