On Tuesday 24 October 2017 we had an introductory webinar about integration of PDF Forms to SharePoint online in O365. We used PDF Share Forms Cloud product to demonstrate that.
This webinar was intended for users new to our products and SharePoint as a whole. Therefore, we did not go too deep and covered only the core functionality of the product.
We used Oreo cookie as an analogy to PDF form. Similar to Oreo, PDF form also has layers that are bound together.

Integration with Share Point and form field synchronization

Later in the presentation we gave a brief overview of SharePoint using Oreo analogy again. Like an Oreo, SharePoint has 2 major elements – Lists and Document libraries. Tight integration with Office products and other 3rd party solutions keeps it together. One these solutions is PDF Share Forms. It enables deep SharePoint and PDF form integration: allows bi-directional form field to SharePoint library column synchronization.
