Many users have asked already for a way to synchronise our user lists database to the user list of the app. This is a very important feature needed for many of us as it will help to keep our clients/customer information up-to-date without having to be updating constantly user information in 2 different places. This will be very easy to implement using REST API. Hope this feature takes priority as it will potentially improve the functionality of your App to many more clients and industries. We are a school and we already have our user database, we don't need our users to create their profiles, we already have that data. And this data changes in a daily basis. Many thanks and I hope to see this functionality soon. I am happy to work with your team with the development.
