Schema Service: TLS versions for outbound APEX
SummaryRecent questions around TLS versions supported for APEX outbound web service requests in Schema Service
Q: For APEX *outbound* web service requests in Schema Service, what TLS versions are supported?
A: This particular scenario is TLS v1.0 only, so the service endpoint that you are communicating with needs to have TLS v1.0 enabled. If the endpoint requires TLS v1.1 and v1.2, then run your APEX app in Exadata Express instead (which supports contemporary versions of TLS).
