Odata POST method Execution using Certificate based Authentication

Hello Experts,

We are trying to integrate c4c system with Microsoft Azure using certificate based authentication.

1. Certificate has been provided to azure team but they are not able to use the certificate as they are getting some error while configuring the same

2. certificate from c4c has worked fine for other third party like PI, HCI etc

Is there any way to test the certificate of C4C to be sure that provided certificate is fine and we need to look into azure side???

I found that we can try testing the certificate with POSTMAN tool but I am confused where to upload the certificate and test it successfully.

I have followed a blog where we found the configuration of postman for certificate but its not working.

Regards,
