Issues with the API: Items - Get Report Definition

[mariussve1]

Hi,

I have been using a lot of the API's from Power BI, and with great luck.

Now I'm creating some cool stuff by using Log Analytics, and one of the things I get from Log Analytics is the VisualID. To connect VisualID to the correct Report page in a report I need to find this in the report.json file. This is something I can get with the Get Report Definition API.

But, when I try to use this API it returns this error message:

"errorCode": "BadRequest",

"message": "Unable to process the operation due to an error in the request"

In the documentaion it does not say anything about the body:
https://learn.microsoft.com/en-us/rest/api/fabric/report/items/get-report-definition?tabs=HTTP

As you can see the doc says its a POST, but no body as I can see. I have tried to use GET as well, but no luck.

When I hit the TRY IT button it works, so that is really strange.

Someone else been in the same situation and can help out?

Hi,

Does anyone knows if this have stopped working? Im not able to get any result from the api.

It only returns:
Resultat: {'status': 'Succeeded', 'createdTimeUtc': '2025-05-23T14:58:32.8582529', 'lastUpdatedTimeUtc': '2025-05-23T14:58:33.3270162', 'percentComplete': 100, 'error': None}

But the payload and base64 code is missing 😞

When I try this "Try it" button here:
https://learn.microsoft.com/en-us/rest/api/fabric/report/items/get-report-definition?tabs=HTTP&tryIt...

It only returns:

I tried to copy the token from "Try It" page of the documentation, and then it works.

I reviewd access to the SPN and found out I needed to grant some more access. Now everything works 🙂

Cheers

I ran a POST call from Power BI and it is working, Follow the below snippet and you should be able to run

let
    Source = Json.Document(Web.Contents("
https://api.fabric.microsoft.com/v1/workspaces/<workspaceId>/reports/<reportId>/getDefinition",[Headers=[Authorization="Bearer <Bearer Token>",#"Content-Type" = "application/json" ], Content=Json.FromValue([])]  ))
in
Source

dont forget to include your report id, workspsce id and bearer token.

Hi,

I will try from Power Query. Are you able to run the request from Postman?

Hi @mariussve1 ,

Did you try calling the API for the same report from the "Try It" page of the documentation Items - Get Report Definition - REST API (Report) | Microsoft Learn ?

If it returns an error, can you please paste here and response headers and body?

Hi, when I use the "try it" button it works, so kt does not give any errors then. Only when I use postman
