Call API requires certificates

Product/components used and version/fix level:

10.15

Detailed explanation of the problem:

Hello community,

I would like to call an API using the pub.client:http service, but this API requires certificates (CRT and KEY files). So, I would like to know how to add these certificates to my call?
I usually attach them in Postman as shown in the attached file.

Thank you in advance.

Hi,

you can map the certificates to an IS User in IS Admin under the Security section (check for “Client Certificates”).
See IS Administrators Guide for details about this.

When invoking the (external?) API from IS service you use service from WmPublic package to set the certificate chain to be used during the invocation.
See IS Built-In-Services Reference for further informations.
