Our Solution Approach - Decoupled Drupal

We first story boarded all the possible scenarios and discovered the existing systems and their touch points in each of the scenarios. We then set out on designing a solution that would run a state machine while interacting with the existing systems such that the desired outcome was achieved. The solution had to be headless/decoupled and API driven as it had to interwork with a large number of external systems and also provide the best performance. An API layer was built in order to consume and provide parameters required to interwork with the existing systems. The API layer formed the interface between the core state machine of our solution and the external entities such as the existing legacy systems as well as the mobile app front end. To enable API based communication on the web front-end, we built it using Angular. Take a look at the main Drupal modules we used.
