CRM 2016 Web API – Impersonate User

January 1, 2016 3 comments

In CRM, Impersonation is possible in Plug-ins (using ‘Run As’ while registering Plug-in step) or using ‘CallerId’ property while instantiating OrganizationServiceProxy.

What if I have to impersonate ‘Retrive’ operation from Jscript? This was not possible.

With advent of CRM Web API with CRM 2016 we can impersonate in Jscript.

What is a Web API :

  • The Web API implements the OData (Open Data Protocol), version 4.0.
  • The new Web API provides better capabilities over the OData service introduced with CRM 2011 and OData service will be deprecating with this release.
  • It provides a modern, RESTful web service you can use to interact with data in CRM using a wide variety of platforms, programming languages and devices
  • The Web API will provide parity with the existing organization service (SOAP endpoint).
  • You can perform all operations using HTTP requests with the Web API located at [organization uri]/api/data/v8.0/

Impersonate another User using Web API:

  • To impersonate a user, add a request header named MSCRMCallerID with a GUID value equal to the impersonated user’s systemuserid before sending the request to the web service.

Sample Script with impersonation to create an Account Record

function createAccount() {
var clientURL = Xrm.Page.context.getClientUrl();
var impersonateUserId = “7eb682f1-ca75-e511-80d4-00155d2a68d1”;// GUID
var req = new XMLHttpRequest()
req.open(“POST”, encodeURI(clientURL + “/api/data/v8.0/accounts”), true);
req.setRequestHeader(“Accept”, “application/json”);
req.setRequestHeader(“Content-Type”, “application/json; charset=utf-8”);
req.setRequestHeader(“OData-MaxVersion”, “4.0”);
req.setRequestHeader(“OData-Version”, “4.0”);
// Set the Caller ID; GUID of User
req.setRequestHeader(“MSCRMCallerID”, impersonateUserId);
req.onreadystatechange = function () {
if (this.readyState == 4 /* complete */) {
req.onreadystatechange = null;
if (this.status == 204) {
var accountUri = this.getResponseHeader(“OData-EntityId”);
alert(“New account created; URI: ” + accountUri)
}
else {
var error = JSON.parse(this.response).error;
alert(“Error creating Account – ” + error.message);
}
}
};

// Set Account record properties
req.send(JSON.stringify({ name: “Rajeev Pentyala”, description: “Account created using Web API”, revenue: 5000000 }));
}

UserId & InitiatingUserId properties in Plugin of CRM

August 19, 2012 3 comments

In CRM plugin, “IExecutionContext” contains 2 properties

  • UserId
    • Gets the GUID of the user for whom the plug-in invokes “on behalf of”.
  • InitiatingUserId
    • Gets the GUID of the user under which the current pipeline is executing.

Consider a scenario

  • You have a user “RAJ” with “Sales Person” role with only “User Level” “Read” privilege on ‘Contact’
  • You have a plugin on Post Deletion of ‘Contact’ with name “PostContactDelete”
  • Assume in one particular scenario user “RAJ” should be able to delete a ‘Contact’
  • So you can run the “PostContactDelete” plugin in the user with “SystemAdministrator” role
    • (i.e., Set “Run in User’s Context” to User with admin role; In sample screen shot below I chosen my admin user whose name is  ‘CRM WaSu1)
Run in User Context

Run in User Context

  • When User “RAJ” logs in and try to delete ‘Contact’ the plug-in “PostContactDelete” fires. When you debug
    • IExecutionContext.UserId = GUID of  SystemAdministrator (i.e., OnBehalfOf User ‘RAJ’)
    • IExecutionContext. InitiatingUserId =GUID of  RAJ   (i.e., Actual User)

Creating OrganizationServiceProxy in CRM2011 custom applications

February 26, 2012 7 comments

Hi,

Below are the steps to instantiate “Organization Service Proxy” which can be used to consume CRM service and perform operations in a  custom application

– Refer “Microsoft.Xrm.Sdk & Microsoft.Xrm.Sdk.Client” .dll’s to your custom application

using Microsoft.Xrm.Sdk;

using Microsoft.Xrm.Sdk.Client;

using System.Net.Security;

using System.ServiceModel.Description;

using System.Security.Cryptography.X509Certificates;

private Uri homeRealmUri = null;

private ClientCredentials credentials;

private Uri organizationUri;

private IOrganizationService service;

private OrganizationServiceProxy serviceProxy;

 credentials = new ClientCredentials();

// If CRM On-Premise

// To use custom credentials pass user credentials

credentials.Windows.ClientCredential = new NetworkCredential( {userId},{ password},{ domain} );

// To use Default Credentials; Uncomment below line and comment above

// credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;

// If CRM Online

credentials.UserName.UserName = “Office 365 ID”; // i.e.,  name@domain.onmicrosoft.com

credentials.UserName.Password = “Office 365 Password”;

// Use “https” if CRM is SSL configured

string orgUrl= “http://ServerName/OrganizationName/XRMServices/2011/Organization.svc”;

// Add this line if URL has “https” (i.e.,CRM is SSL configured)

if (!string.IsNullOrEmpty(orgUrl) && orgUrl.Contains(“https”)) {

ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain,
SslPolicyErrors sslPolicyErrors) { return true; };

}

organizationUri = new Uri(orgUrl);

using (

serviceProxy =

new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, null))

{

// To impersonate set the GUID of CRM user here

serviceProxy.CallerId = {GUID of CRM User};

serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());

service = serviceProxy;

}

Hope it helps 🙂
