Access Application Insights API to query telemetry

4 min

Application Insights API Access lets you query telemetry from Application Insights for a specific environment.

Generate API credentials

Go to your project in the DXP portal and select the API tab.

Select an environment and click Generate API Access in the Application Insights API Access section. This action generates and displays the information needed to access Application Insights. Credentials last for 1 year after being generated and will need to be re-generated after that point.

❗️ Warning This action removes all previously generated secret credentials. Any access using previously generated credentials will be lost.

The secret is only shown once, while other variables are static.

Access to Application Insights through the API

Acquire Token (OAuth 2.0 Client Credentials). Replace TENANT_ID, CLIENT_ID, and SECRET with your information from the previous section.

curl -X POST \
  -H "Content-Type: application/x-www-form-urlencoded" \
  https://login.microsoftonline.com/TENANT_ID/oauth2/token \
  -d "grant_type=client_credentials&client_id=CLIENT_ID&client_secret=SECRET&resource=https%3A%2F%2Fapi.applicationinsights.io"

The response contains your access_token.

Run an Analytics Query. Replace APPLICATION_INSIGHTS_ID with your information from the previous section.

curl -X GET \
  -H "Authorization: Bearer ACCESS_TOKEN" \
"https://api.applicationinsights.io/v1/apps/APPLICATION_INSIGHTS_ID/query?query=requests%20%7C%20take%2010"

Access to Application Insights through code

Replace APPLICATION_INSIGHTS_ID, TENANT_ID, CLIENT_ID, and SECRET with your information from the Generate API credentials section.

using System.Net.Http.Headers;
using System.Text;
using System.Text.Json;
using Azure.Identity;

public class ApplicationInsightsDataQuery {

  public static async Task Main(string[] args) {
    try {
      string ApplicationId = "APPLICATION_INSIGHTS_ID";
      string tenantId = "TENANT_ID";
      string clientId = "CLIENT_ID";
      string clientSecret = "SECRET";

      // Authenticate with Service Principal
      var credential = new ClientSecretCredential(tenantId, clientId, clientSecret);
      var token = await credential.GetTokenAsync(
        new Azure.Core.TokenRequestContext(
          new [] {
            "https://api.applicationinsights.io/.default"
          }
        )
      );

      using var httpClient = new HttpClient();

      httpClient.DefaultRequestHeaders.Authorization =
        new AuthenticationHeaderValue("Bearer", token.Token);

      // Example query: last 5 requests
      var query = new {
        query = "requests | take 5"
      };

      var content = new StringContent(JsonSerializer.Serialize(query), Encoding.UTF8, "application/json");

      var response = await httpClient.PostAsync(
        $ "https://api.applicationinsights.io/v1/apps/{ApplicationId}/query",
        content
      );

      var result = await response.Content.ReadAsStringAsync();
      Console.WriteLine(result);
    } catch (Exception ex) {
      Console.ForegroundColor = ConsoleColor.Red;
      Console.WriteLine($"\nAn error occurred while attempting to query Application Insights:");
      Console.WriteLine($"Error Type: {ex.GetType().Name}");
      Console.WriteLine($"Message: {ex.Message}");
      Console.ResetColor();
    }
  }
}
