XMLHttpRequest on Form Save

Posted on by Community Member Microsoft Employee

I am trying to send a POST request to my Web API on a Entity Form Save. The script is run but my function is not being accessed. I am using a XMLHttpRequest to pass an ID to an API controller.

function createSiteRequest () {
var id= Xrm.Page.data.entity.getId();
var url = "site.cloudapp.net/.../Action" + id;
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState == XMLHttpRequest.DONE) {
alert(xhr.responseText);
}
}
xhr.open('POST',url, true);
xhr.send(null);
}

This seems to be a very basic setup that is working correctly when I use Postman. Does Dynamics restrict requests like this?

Thanks!

RE: XMLHttpRequest on Form Save

You will need to use a CORS technique to post to an external domain - or if you have access to the webservice you can add the cross domain headers (XMLHttpRequest.setRequestHeader("Access-Control-Allow-Origin", "*.crm.dynamics.com"); - see community.dynamics.com/.../179866

You could also do the request on the server and call it from an action - see salimadamoncrm.com/.../crm-2013-actions-to-get-around-javascript-cross-domain-challenges

Hope this helps

RE: XMLHttpRequest on Form Save

It seems like this is a cross domain issue. I implemented a JSONP and CORS solution with no luck either.
