Getting data from Dynamics CRM 365 in json

Question

I need to get data from Dynamics CRM 365 Online. Anyone tried this before ?

I need to know what kind of information (clientid, clientsecret) I need, to connect through c sharp and save data (JSON) into a for example a flatfile.

edit: use ADAL.Net v2 If you need to use the non async method. Remember to put the Token in the request header under "Authorization".

Answer 1

You need to use OAuth to authenticate to Dynamics 365 Online from your C# code.

// TODO Substitute your correct CRM root service address,   
string resource = "https://mydomain.crm.dynamics.com";  

// TODO Substitute your app registration values that can be obtained after you  
// register the app in Active Directory on the Microsoft Azure portal.  
string clientId = "e5cf0024-a66a-4f16-85ce-99ba97a24bb2";  
string redirectUrl = "http://localhost/SdkSample";  

// Authenticate the registered application with Azure Active Directory.  
AuthenticationContext authContext =   
    new AuthenticationContext("https://login.windows.net/common", false);  
AuthenticationResult result = authContext.AcquireToken(resource, clientId, new Uri(redirectUrl));  

You can then use the AuthenticationResult to make HTTP requests with HttpClient :

using (HttpClient httpClient = new HttpClient())  
{  
    httpClient.Timeout = new TimeSpan(0, 2, 0);  // 2 minutes  
    httpClient.DefaultRequestHeaders.Authorization =   
        new AuthenticationHeaderValue("Bearer", result.AccessToken); 
//TODO Implement your WebApi calls
}
