Integrating Django and Flask with Zato services
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 :-)

self.log_input()
# Customer ID received on input
cust_id = self.request.payload['cust_id']
# Do we have their name in cache?
name = self.kvdb.conn.hget(CACHE_KEY, cust_id)
# If not, we need to ask the backend and cache the response
if not name:
name = self.get_customer(cust_id)
self.kvdb.conn.hset(CACHE_KEY, cust_id, name)
# Produce the response for the calling application.
self.response.payload = {'name': name}
