Remote Pings from a membership site to another membership site

Hi, WPMU Team

I'm using the membership plugin.
In the tutorial, you gave only the example of pings with Mail Chimp. I got lost

I have a membership site A.
Required data:
- Name
- Email
- Username
- Subscription level
- Password

After registration, I want the same member to be automatically registered in my membership site B.
Required data:
- Name
- Email
- Username
- Password

How to ping such data?

Best regards,

Mike
