I am new in development area. Here is my requirement which I want to complete.
I have 3 SharePoint lists. These lists will have data maintained by some users. Now, whenever there is any change (add/modify/delete item) in these lists, I have to send this updated data to an external Application (non-SharePoint; i'll call it EA) so that the data is in sync between both applications (SharePoint and EA). I am provided with a schema based web service from EA and I have to make a call to this web service whenever data changes in SharePoint List, populate the attributes so that they can be fetched and data can be updated in EA.
How can I do it?
