Hi, I’m trying to connect a SAP system with these APIs but I’m getting an error about the certificate. Calling the service with Postman I noticed that the final certificate is not the one present on the site. In particular, it differs in who issued it and in the possible hosts.

*** ERROR => SSL handshake with fatturacheck.p.rapidapi.com:443 failed: SSSLERR_PEER_CERT_UNTRUSTED (-102)
