How do you use the Office365.Groups.HttpRequest(URI, Method, file)

Posted on by Justin-GOV

I would like to query Graph from PowerApps by providing a Group DisplayName or mailNickName.

Currently this works in Graph Explorer - https://graph.microsoft.com/v1.0/groups?$filter=mailNickname eq '<nickname>' but I can't find any documentation to use the Office365.Groups.HttpRequest("https://graph.microsoft.com/v1.0/groups?$filter=mailNickname eq '<nickname>'", "GET", file) to make it work.

What am I supposed to use for 'file'?

Where do I find information about how to structure the formula in PowerApps? I am trying to use instructions from this docs.microsoft.com page: Office 365 Groups - Connectors | Microsoft Docs

Hi @Justin-GOV ,

Unfortunately, this parameter (file) has not been introduced in the documentation.

I suggest you use Office365.Groups.HttpRequest action in flow.

Thank you for your reply @v-xiaochen-msft. Do you have an example where Office365.Groups.HttpRequest works? It seems the 'file' parameter is required. I can't use the action because it's expecting 'file.'

Specifically, I get the error: 'Invalid number of arguments: received 2, expected 3-4.'

Thanks again,
Justin

Hi @Justin-GOV ,

No. I don’t know what to fill in the parameter. 😞

Hey,
I also took a look at this connector. The "file" property seems to be the request body. But unfortunately, there is no out of the box way to work with the result. Looking at the monitor results it clearly shows that the request is correct and also that there is a propper result. I have used:

Set(varMe,Office365Groups.HttpRequest("https://graph.microsoft.com/v1.0/me","GET","",{ContentType:"application/json"}))

And varMe is set to "true".

Look at this excellent video to see how you could get a propper result which you could use in PowerApps.

Thanks to @PowerRanger and the excellent video he provided ,

I was able to create a working example

https://powerusers.microsoft.com/t5/Building-Power-Apps/Office365Groups-HttpRequest-Formula/m-p/1929136#M484573

and also get more properties from the Get User Profile V2 for PowerApps - when using $select

So PowerApps has had a couple updates in the past few months to help enable this functionality. You can now send any HTTP request through PowerApps natively (without having to export the msapp file and tinker with it in VS Code) - just by making sure that the "ParseJSON and Untyped Objects" preview feature is turned on. It seems to be turned on by default in all new apps (at least in my version of PowerApps), so that's helpful - but if you have an older app and don't have it turned on - turn it on, then save and reload your app editor screen.

So, what that allows you to do is actually parse the response from the action (which after you turn it on, is returned as an "untyped object" rather than boolean true/false) and you can type-cast properties from your response individually. Here's a great example in MS Documentation: Working with untyped and dynamic objects - Power Apps | Microsoft Learn - they even use the HttpRequest() action there. Problem is that they use a "GET" request that doesn't require a Body input so there's no example on that.

If you want an HTTP request that includes a body input - that does need to be of a "file" type. You can't just type in your request in JSON formatting, you have to have it set up as a file. You can do this by adding an Image control, putting "data&colon;text/plain;base64," as your Image property - and then convert your JSON payload from string to Base64 using the method described in this blog post: Encode/Decode Base64 in Power Apps without Flow - MoreBeerMorePower (hatenablog.com) and concatenate all that together.

When you go to call your HTTP request, it'll look like this:
Office365Groups.HttpRequest("https://graph.microsoft.com/v1.0/groups/{groupId}","PATCH",Image1.Image)
Where your Image1.Image is just your data-URI encoded Base64 body for your request.

Is this way more complicated than it needs to be? Yes, absolutely - but you don't need a Flow to call an HTTP request and get a response anymore.

Hello, I have turned on ParseJSON and Untyped Objects and reload the app. But the file type is still boolean for offficr365group. Any reason why?
Thanks

Remove the connector save and exit. Open the app add the connector back, save and exit. Then open it once more and it should now display Untyped Objects instead of boolean.

Hey dotter... I'm trying your method out to create a new folder in SharePoint. The Image1.Image value is data&colon;text/plain;base64,SGFwcHkgSG9saWRheXM= which is the text you said to lead with, and the result of the "encode plain text to base64" directly from the link you provided ("Happy Holidays" in this case). I am still getting the error "Empty Payload. JSON content expected."

Any thoughts as to what I could be doing wrong? Thank you!

Office365Groups.HttpRequest(
"https://graph.microsoft.com/v1.0/sites/<site guid>/drive/items/root/children",
"POST",
Image1.Image);

I've been fighting this for nearly 2 solid days, many thanks to dotter for putting me on the right track. So here's how I did it, forget the image box you don't need that. Just generate yourself the proper string and put it into a variable, then send that to the httprequest. The reason why dotter's example code didnt work for you as typed is because of a slight error it should be "data:" not "data&colon;" (some kind of html decoding issue somewhere along the line I guess)

For testing, I made 2 buttons to quickly generate the required string then post it into a list on our sharepoint site. Button1.OnSelect:
Set(myJSONString, "{""fields"":{""Title"":""John Smith""}}" ); Set(myBinaryString,With({ InputText:myJSONString, AsciiTable:AddColumns(Sequence(2^8,1),"char",Char(Value)), B64ToBin: Table( {b64:"A",bin:"000000"}, {b64:"B",bin:"000001"}, {b64:"C",bin:"000010"}, {b64:"D",bin:"000011"}, {b64:"E",bin:"000100"}, {b64:"F",bin:"000101"}, {b64:"G",bin:"000110"}, {b64:"H",bin:"000111"}, {b64:"I",bin:"001000"}, {b64:"J",bin:"001001"}, {b64:"K",bin:"001010"}, {b64:"L",bin:"001011"}, {b64:"M",bin:"001100"}, {b64:"N",bin:"001101"}, {b64:"O",bin:"001110"}, {b64:"P",bin:"001111"}, {b64:"Q",bin:"010000"}, {b64:"R",bin:"010001"}, {b64:"S",bin:"010010"}, {b64:"T",bin:"010011"}, {b64:"U",bin:"010100"}, {b64:"V",bin:"010101"}, {b64:"W",bin:"010110"}, {b64:"X",bin:"010111"}, {b64:"Y",bin:"011000"}, {b64:"Z",bin:"011001"}, {b64:"a",bin:"011010"}, {b64:"b",bin:"011011"}, {b64:"c",bin:"011100"}, {b64:"d",bin:"011101"}, {b64:"e",bin:"011110"}, {b64:"f",bin:"011111"}, {b64:"g",bin:"100000"}, {b64:"h",bin:"100001"}, {b64:"i",bin:"100010"}, {b64:"j",bin:"100011"}, {b64:"k",bin:"100100"}, {b64:"l",bin:"100101"}, {b64:"m",bin:"100110"}, {b64:"n",bin:"100111"}, {b64:"o",bin:"101000"}, {b64:"p",bin:"101001"}, {b64:"q",bin:"101010"}, {b64:"r",bin:"101011"}, {b64:"s",bin:"101100"}, {b64:"t",bin:"101101"}, {b64:"u",bin:"101110"}, {b64:"v",bin:"101111"}, {b64:"w",bin:"110000"}, {b64:"x",bin:"110001"}, {b64:"y",bin:"110010"}, {b64:"z",bin:"110011"}, {b64:"0",bin:"110100"}, {b64:"1",bin:"110101"}, {b64:"2",bin:"110110"}, {b64:"3",bin:"110111"}, {b64:"4",bin:"111000"}, {b64:"5",bin:"111001"}, {b64:"6",bin:"111010"}, {b64:"7",bin:"111011"}, {b64:"8",bin:"111100"}, {b64:"9",bin:"111101"}, {b64:"+",bin:"111110"}, {b64:"/",bin:"111111"} )}, With({ BinRep: Concat( AddColumns(ForAll(Split(InputText,""), {Result: ThisRecord.Value}),"dec",LookUp(AsciiTable,char=Result).Value),//Convert text to Ascii character code (decimal) Concat(Sequence(8,8,-1),Text(If(And(Mod(dec,Power(2,Value))>=Power(2,Value-1),Mod(dec,Power(2,Value))<Power(2,Value)),1,0)))&"","")//Convert decimal to binary }, With({b64string:Concat( Sequence( RoundUp(Len(BinRep)/6,0),0), LookUp( B64ToBin, bin=Mid(BinRep&Left("000000",6-Mod(Len(BinRep),6)),6*Value+1,6) //Left("000000"....) is padding right with zero ).b64&"", "" )}, b64string&Left("====",Mod(4-Mod(Len(b64string),4),4))//Convert binary to base64 ) ) )); Set(myGeneratedBlob,"data&colon;application/json;base64," & myBinaryString)
