Hi,

I want to send the event data to application insight using RestAPI, i don't want to use programming language rather use pure RestAPI approach.

Based on my research i see following endpoint works well but want to know is it officially supported.

can you please let me know on this?

curl --location 'https://XXXXXX.applicationinsights.azure.com/v2/track' \
--header 'Content-Type: application/json' \
--header 'x-api-key: XXXXXX415dmjhewu3' \
--data '{
  "name": "Microsoft.ApplicationInsights.Event",
  "time": "2024-11-20T12:34:56.789Z",
    "iKey": "XXXXXX-8d727737eddf",
  "tags": {
    "ai.cloud.role": "my-service",
    "ai.operation.name": "my-operation"
  },
  "data": {
    "baseType": "EventData",
    "baseData": {
      "ver": 2,
      "name": "MyCustomEvent",
      "properties": {
        "CustomProperty1": "Value1",
        "CustomProperty2": "Value2"
      }
    }
  }
}'

Hi ,

Thanks for reaching out to Microsoft Q&A.

Yes, you can send custom event data to Azure Application Insights using the officially supported REST API without requiring any programming language. This is achieved via the v2/track endpoint, which allows you to ingest telemetry data through simple HTTP requests.

Ingestion endpoint

https://<resource>.applicationinsights.azure.com/v2/track

Replace <resource> with your Application Insights resource name.

Is This Officially Supported?

Yes, the v2/track endpoint is officially supported by Azure Application Insights for sending telemetry data, including custom events. The use of the x-api-key header for authentication aligns with the Azure documentation.
