How to query our Salesforce data from the front-end

Hi,

We'd like to be able to query some of our Salesforce data from our front-end web app in order to get some information back for the current application user. Specifically we would like to query Salesforce based on a contact role email address in order to determine what Salesforce accoutn they are associated as well as retrieving information from related account opportunities. 

Thanks, Paul

Hey Paul,

Is your web app an VF page or what kind of app it is ??
Paul HowePaul Howe
Hi Vinit,

Its not a VF page (Im not familiar with VF in any case), its just our web application that we would like to communicate from to Salesforce to get information about contacts in our Salesforce database.

Hi Anil,

Thanks for the information. Do we need to install a package on our SF page to be able to make requests for SF data (i.e. sforce.connection.query() ...) ?

Paul,

You need to use Salesforce APIs(SOAP or REST) whichever you prefer.

I would suggest to use SOAP in which you need to consume salesforce WSDL file in your webapp and then you can make calls to salesforce and fetch Contacts data from there.

Hope this helps !!
