The API utilises the following protocols over HTTPS (secure web service):
These protocols are lightweight, widely supported and industry standard options. The above formats enable much easier integration compared to many other traditional data-interchange formats. It also allows the continuation of development without further development being required each time changes to the schema are made in the database. A myriad of third-party developers and systems have done their own integration with simPRO including vehicle tracking systems, phone systems, estimating and collaboration tools.
