I can't access Recruiting Posting when trying to post jobs in my ATS.

SAP SuccessFactors Recruiting Posting

                  Integration type: non-SuccessFactors web service integration

Your ATS web service posting request can be incorrectly configured.

Since the beginning of December 2020, Recruiting Posting web service URLs need to be set up with HTTPS instead of HTTP. 

The error message may vary according to the ATS. We suggest to check with your provider before raising any Support ticket.
