Hi,

We have several components that make it easy to integrate your line-of-business applications (LOB) with your SharePoint lists and document libraries.

• LOB Item Link Field serves as a kind of lookup field that displays and links to data stored in external databases and application. For instance, create an invoice with the prices coming directly from your sales database.
• Smart Action Pro allows you to run stored procedures and web service calls to update data in external application based on changes in your SharePoint lists. Use it to sync your LOB system with changes in your lists.
• Smart Import Pro allows you to schedule automatic recurring import of emails, database items or web service entities that were created or modified since the last run of the import job. Create new support tickets or set approval through emails or sync product lists from databases.

We've been supporting SOAP web services for a while now, but as more and more users are switching to using the simpler REST services, we are adding support for them as well. LOB Item Link Field and Smart Action Pro have already been upgraded to include REST support and Smart Import Pro is scheduled tobe upgraded within a few days.

Now you are able to integrate with this simple and ubiquitous API from any list or document library!
