Get Api Version Dynamically For WebApi Requests

Loads of my blog readers wanted to know..here is the perfect link to it.

Passion Dynamics

In this post I will quickly cover the requirement of dynamically getting API version of dynamics CRM in JavaScript rather then hard coding it , so that in next releases your JavaScript doesn’t breaks. I am referring to this:

1

For Dynamics CRM version 8.2 or below, do this:

var apiVersion = Xrm.Page.context.getVersion();

For Dynamics CRM version 9 or above, do this:

var apiVersion = Xrm.Utility.getGlobalContext().getVersion();

2

It will give you an expended version which includes minor and major versions. Now, all you have to is crop the number to get only initial number such as 9.1 in this case:

var shortVersion= apiVersion.substring(3, myStr.indexOf(“.”) -1);

then finally use it in your request as:

    req.open("GET",Xrm.Utility.getGlobalContext().getClientUrl()+ "/api/data/"+shortVersion+"/systemusers

Hope this helps!
