Polling Power BI Dataset refresh status (statusCode)

(1) Share

Report

Posted on by RobertSlattery

When a Dataset is refreshed with the Refresh a dataset action, querying statusCode will return 202 as soon as the refresh is triggered. I want to confirm that the refresh completed and test if it is 200 or 400 afterwards, to check if it was successful but, running int(actions('Refresh_a_dataset').outputs.statusCode) always returns 202. How can I get the status to update after the refresh has completed? I can see from the refresh history that it was well and truly completed before the do while timed out.

Hi, I'm looking to do something very similar, did you get a solution? I have a power app where the user will trigger a flow and it is refreshing the dataset but I want to send back a running statuses so that the user will know when it has finished.

@RobertSlattery did you find any solution to this? I am dealing with the same scenario

I think there is a solution but I haven't put together yet. I think you will have to make an http request to Power BI API to get the refresh history, as this shows if it is running or finished. It would be easier if it was part of the standard connector, may be this could future feature request.

I do have a solution but it is not straight forward and might look more complicated than it really is.
These are the steps I took

Created an App Reg in AD and a custom connector - I followed this post https://medium.com/@Konstantinos_Ioannou/refresh-powerbi-dataset-with-microsoft-flow-73836c727c33 (just be care this post references POSTing a refresh, you want to do a GET)
Then in the flow I called the custom connector to get the refresh history and parse to JSON, which means I could use the history data returned.
There are many options from this point, loop to keep checking the status until complete, write to a table, display in the power app etc.

Interesting... Is it working for you? I will give it a try early next week. Have you included a "Do until" control flow to loop until getting the desired StatusCode?

yes, I have used a "Do until" by parsing the result to JSON / schema but half way through completing the development, I've realised the workspace is only set to pro, so I can only make 8 API calls. I'm going to pick it up again next week. If I get the time, I'll try and fully document or at least I'll post a screen shot of the flow but there is a solution, it is just not very elegant. It would be far easier if the OTB power bi connector had a return dataset history.

Jason any chance you could still post a screenshot of your solution. Currently working through this issue. Thanks!

I did developed a solution, the custom connector was really difficult to work with when deploying between environments and it would constantly need re-authenticating. I used API calls via Data Factory. I just found it really easy to work with Data Factory, I'm sure there are many other ways to do the same thing.

so... Power App > Button > Executes a Flow > Flow makes an HTTP API call to a Azure Data Factory Pipeline which refreshes the Power BI dataset > Flow checks the status of the pipeline. The pipeline was reusable for any Power BI dataset as it was parametrised.

For the Data Factory I followed this post, I copied the json from the github into a new Data Factory and changed as needed - https://datasavvy.me/2020/07/09/refreshing-a-power-bi-dataset-in-azure-data-factory
Within the flow I make an HTTP API call to Data Factory pipeline and check the status of the pipeline with a Do Until - The flow is heavily parametrised to make it environment agnostic. It made it easier to deploy to different environments.
These are the MS docs I used as reference.
