Head over to the new chapter in the Zato documentation to find out how to integrate Django and Flask applications with Zato services.

The service it uses is a hypothetical yet fully functional one which looks up and caches user data by their IDs.

The integration effort is presented from the point of view of both libraries using self-contained ready-to-use projects living on GitHub.

Simply put - it contains everything you need to integrate Django or Flask with Zato :-)
