Hi Readers, We already have two posts about NAV 2018 API listed below - Microsoft Dynamics NAV 2018 - API Part 1. Microsoft Dynamics NAV 2018 - API Part 2 - Configure API. In this article, we will see how we can consume these APIs. For the Demo, I will use Google Chrome App called Postman. I am sure there are great developers out there who know how to consume it but I just wanted to test how it is consumed. If you are interested in the small demo using Postman then please go further otherwise, i am sure you know how to consume these APIs.
