I am trying to call one URL through apex callouts but it is throwing this exception : "sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" The same call is working with Postman/RESTlet Client. Can anyone tell me the exact issue. I am not getting it.
