How to make interaction of two applications?

Question

Yii

Hello!
Help a newbie understand... there are two sites, for example, a new post is created on one of the sites and it is necessary that after the post is created, the post data is automatically sent to another site... How best to do this?

Answer 1

Simple: by adding a wrapper-pipe to another site in the handler of a new post that came from the front (when you clicked "create").
front->back-site1->back-site2
