Hi Michel,

Using CRM web resource you can call OData services using Ajax call.

Odata query reference link : msdn.microsoft.com/.../gg309461(v=crm.7).aspx

Ajax call reference link:

Hi Michel,

You can use an XMLHttpRequest with OData to call the CRM webservice endpoint. I've used the following javascript function to retrieve a record in CRM:

function RetrieveRecord(id, entityType, select, expand, sCallback, eCallback) { var sURL = Xrm.Page.context.getClientUrl(); // Make sure the trailing / is there if (sURL.charAt(sURL.length - 1) != '/') sURL += '/'; var _ODataPath = sURL + "XRMServices/2011/OrganizationData.svc/"; var systemQueryOptions = ""; if (select != null || expand != null) { systemQueryOptions = "?"; if (select != null) { var selectString = "$select=" + select; systemQueryOptions = systemQueryOptions + selectString; } if (expand != null) { systemQueryOptions = systemQueryOptions + "&$expand=" + expand; } } var url = _ODataPath + entityType + "Set(guid'" + id + "')" + systemQueryOptions; //alert(url); var req = new XMLHttpRequest(); req.open("GET", url, true); req.setRequestHeader("Accept", "application/json"); req.setRequestHeader("Content-Type", "application/json; charset=utf-8"); req.onreadystatechange = function () { if (this.readyState == 4) { if (this.status == 200) { var retrieved = JSON.parse(this.responseText).d;
// Do something } else { if(eCallback != null) eCallback(req.statusText); } } } req.send(); }

Hope that helps.
