When working with Drupal as a backend for mobile applications, and serving the information via RESTful services, it is important to limit the number of needed requests from the site to the minimum.
Unfortunately, sometimes Drupal makes things harder.

When working with Drupal 6 mapping few years ago, there where limited number of mapping solutions, which mainly focused on the integration between gmap and location modules.
In part III we described the creation of a cart with a subscription information in it (the product with the Interval field).

In part I we described the requirements and what we found out in the existing modules.
In this part we will describe How we build the Drupal Commerce order to be paid.
