Application insights failing with invalid instrumenation key, even after providing right key

Question

Hi I wanted to push custom events to application insights via REST API from logicapp. Please guide on the right approach

URL : https://<<App insight ingestion url>>/v2/track

Header: x-api-key: <<GUID>>

Operation: POST

I am receiving 400 bad request app insights as below

I also tried with managed identity enabled approach, that as well giving the same error. Please guide on the same

{  "itemsReceived": 1,  "itemsAccepted": 0,  "appId": null,  "errors": [    {      "index": 0,      "statusCode": 400,      "message": "Invalid instrumentation key"    }  ]}

Answer 1

@Vignesh Sukumar As per the error it doesn't look like authentication issue rather the request that you are passing is not correctly formed. In case the issue is resolved with the help of Ben then feel free to post as answer so it can help other community member facing the similar issue.

Answer 2

Able to resolve this issue by adding the ikey in the payload, not just in Headers.
