I need to send user data (some parts of
user_meta), from Website A to Website B (both are Wordpress Websites) over a secure Protocol, after clicking on a button. According to this post, a secure method would be the ssl protocol (https).
Or in other words, I need the user data of Website A also on Website B (different Server). I have full access to both sites.
What are the best practice and are there already some tools to do that? Where to find good documentation for this task?
In my research I could find only Client to Server communication like here: developer.mozilla.org/Sending_and_retrieving_form_data.
But I'm looking actually for ways to send data to another website (on another server). I guess my case is server-to-server communication?
Thanks in advance for your help!
