Get Key Prefix/Object id of Object in JavaScript

By | November 2, 2013

Few days back, while working on a project we needed to have a Key Prefix of our Object called Client__c in our JavaScript code for further processing. We didn’t want to hard code Key Prefix of Client__c. The reason is that when we deploy our package for different Organizations, Key Prefix would automatically get created. It could be anything but the object name would remain the same i.e. Client__c.

New Stuff :  Mapping custom lead fields to standard contact fields

Here is the code snippet to get the Key Prefix of Object called Client__c that we found after searching –

sforce.connection.sessionId = ‘{!$Api.Session_ID}’;

var result = sforce.connection.describeSObjects([“Client__c”]);

var clientPrefix = result[0].keyPrefix;
