Hi,I am new to this power bi. Can someone please tell me how to connect the Azure Devops REST API into the power bi.The API I am trying to connect is "https://vsrm.dev.azure.com/****/_apis/release/definitions?api-version=5.1". Thanks & Regards,Sujeesh

Oh, that isn't zip I think. It should be JSON. Just apply the line I gave in the previous post of the zip function. The zip function is useful if you want to download a bunch of files out of git. I did this myself once to do a git blame summary This is what your query should look like: let Source = VSTS.Contents("https://vsrm.dev.azure.com/fe-tfs/_apis/release/definitions?api-version=5.1"), #"Imported JSON" = Table.FromRecords(Json.Document(Source,65001)[value]) in #"Imported JSON"

If you need to unzip any files that you get use this function, the other ones I've seen online don't work with devops:

// Unzip

    uint = BinaryFormat.ByteOrder(BinaryFormat.UnsignedInteger32, ByteOrder.LittleEndian),

Thank you for the reply. As per the above solution, i tried the below function. but i get the error as below

DataFormat.Error: There was a problem reading the binary format at position 167780. The end of the input was reached before the value could be read.

Please correct me if i have done any changes incorrectly.

This is what your query should look like:

let Source = VSTS.Contents("https://vsrm.dev.azure.com/fe-tfs/_apis/release/definitions?api-version=5.1"), #"Imported JSON" = Table.FromRecords(Json.Document(Source,65001)[value]) in #"Imported JSON"

This worked excellent tfor what i needed and in fact did in in powerquery for excel before migrating to PowerBI. I will admit to just copy-pasting and filling in my details so i dont understand the storage aspect. Where does the zip file go? is it simply downloaded, extracted and discarded or am i missing it altogether.

artemus - Is this function posted on its own anywhere? Otherwise, my follow up question is what causes the error (the number below appears to be equal to what I'm getting for the length of the zip file in lbendlin's zip function😞
There was a problem reading the binary format at position 7843840. The end of the input was reached before the value could be read.
The zip file contains csv and json files where some filenames contain characters like "é" which appear as "�" in Power Query. Could those be causing the above error?

  You are probably using a ZIP64 arcieve, which I didn't implement here.

  Thank you for clarifying my doubts. It worked
  I got the result as a JSON file. Can you tell me how to convert this JSON file as a table so that I can use this data in my chart

THANK YOU!!!! I'm now able to connect to an online zipped database in Power BI, and now I'm a serious data badass.

Thank you 🙏
