Posted on by mvilas02 356

Hi ,

I have scenario where I have CRM Organization A , which has HTML webresource which is fetching account data using WebApi

What I would like to do is , I want my HTML web resource in Organization A to fetch account data from Organization B using WebApi.

Have anybody tried this ?

    Hi ,

    Thanks for your reply.

    But I have IFD CRM configured and my Active Directory is not on Azure.

    how can I get the information for following parameters. ?

    var organizationURI = "https:// [organization name].crm.dynamics.com"; //The URL to connect to CRM Online

     var tenant = "[xxx.onmicrosoft.com]"; //The name of the Azure AD organization you use

     var clientId = "[client id]"; //The ClientId you got when you registered the application

     var pageUrl = "http://localhost: [PORT #]/SimpleSPA.html"; //The URL of this page in your development environment when debugging.

    I am trying to access Another CRM Organization data from one CRM instance from HTML web resource using Web Api.

    Regards,

    Vilas

    Hi Vilas M,

    You cannot access Web Api from one Org to another directly. In order to authenticate you will need an Authentication method.

    You may refer the below link for more details on Authenticating WebAPI:

    http://www.inogic.com/blog/2016/03/programming-using-webapi-through-c-in-dynamics-crm-2016/ 

    The code is using C# you may refer it for understanding Authentication.

    For javascript you may refer this link: https://msdn.microsoft.com/en-us/library/mt595797.aspx 

    Hope this helps!

    Thanks!
    Sam

    Web Api is organization specific.Think you need to authenticate via oAuth(even if same credentials) or any other authentication mechanisms if you want data from another organization/another CRM URI . please refer links below which will help you.

    msdn.microsoft.com/.../dn531009.aspx

    debajmecrm.com/.../knowhow-how-to-execute-web-api-calls-to-microsoft-dynamics-crm-from-an-external-asp-net-web-application

    For Web Api Intro : msdn.microsoft.com/.../gg334279.aspx

    Quick Code :

    private static void Helper()

    {

    // Obtain an authentication token to access the web service.

    AuthenticationContext authenticationContext = new AuthenticationContext(_oauthUrl, false);

    AuthenticationResult result = authenticationContext.AcquireToken(_authorizationCode, _clientID, _redirectUrl);

    _crmOauthToken = result.AccessToken;

    }

    Thanks.
