Secure Transmission of Snapshots to Web API

[Oppiie]

I've been looking everywhere for info on cameras that can do the following:

1. Take a snapshot either regularly or triggered by an event;
2. Send the snapshot securely to a specific Web API (i.e. to
   https://myAPI.com/snapshot
   ).

All I'm finding is cameras that:

• Send through FTP (some rare cameras might have SFTP, but that's still not to a web API);
• Send through SMTP (I've never seen a camera that supports SMTPS...);
• Upload full video feed through RTSP.

Am I asking for too much, misunderstanding some concepts, or just not looking at the right place ?
