I'm creating users from PowerShell scripts by POSTing data collected from AD to a REST API enabled web portal, using:
$response = Invoke-RestMethod -Method Post -Uri $url -Headers $headers -Body $body
where $body is a JSON formatted propper payload, like this:
{
"email" : "klaus.mueller#domain.com",
"firstname" : "Klaus",
"lastname" : "Müller",
"active" : "true",
"superadmin" : "false"
}
If there is no german letter in name, all is O.K. and user is created. When there is a german character, I get 400 : Bad Request response from server.
Can I somehow change the behaviour of Invoke-RestMethod with setting encoding or its the server maybe configured not to receive de characters?
This is similar to this question.
As #Keith Hill stated
The string in PowerShell is Unicode but you've specified a UTF8 encoding so I think you need to give it some help getting to UTF8.
While the linked thread refers to Invoke-WebRequest, the encoding should still be valid for Invoke-RestMethod.
Your request should look something like this
$response = Invoke-RestMethod -Method Post -Uri $url -Headers $headers -Body ([System.Text.Encoding]::UTF8.GetBytes($body))

I am trying to extract a streaming response from a standard http GET call using PowerShell.
I tried to do something like using this Invoke-RestMethod method, such as:
$response = Invoke-RestMethod -Uri $uri -Method GET -Headers $headers -Body
and then tried doing various things like accessing the streaming response in this way:
$Stream.Write($response.Content)
or
$Stream.Write($response.RawContentStream)
but nothing works.
In the end, I found out the following command does both the call and the response along with allowing you to save the result to a file directly. This surprised me because the response is a multipart record that includes headers and other data, not just the chunked file in the stream. But the folks at MS apparently knew that 99% of the time with a chunked reply, the user only wants to save the streamed chunks of data into the file, without the other response header data.
$Response = Invoke-WebRequest #Params -Headers $headers -outfile $TempZipFileName
The key here is using the Invoke-WebRequest call with the -outfile option. This saved me a lot of headache and was super simple to use.
I'm trying to make a PowerShell script, which will be run from a power-automate flow, and which in turn is supposed to call different power-automate flows via a Http request, the Url used here is generated by power-automate flow. My issue arise when I try to do
Invoke-Webrequest -Uri https://xxxx-xxx.westeurope.logic.azure.com:xxx/workflows/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/triggers/manual/paths/invoke?api-version=2016-06-01%26sp=%2Ftriggers%2Fmanual%2Frun%26sv=1.0%26sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxx -Method POST -Body $PostParams
And when this is run, I get the error of
The Api-Version '2016-06-01&sp=/triggers/manual/run&sv=1.0&sig=xxxxxxxxxxxxxxxxxxxxxxxxxxxxx-rmZzrBfsAvjCc' is not valid. It goes on to suggest some valid ones, which among them are '2016-06-01'.
I have tried removing %26sp, which also did not work. I've tried searching up any information regarding Api-version is not valid, but yielded no result.
I think you should do Invoke-RestMethod
$request = 'https://put_here_your_uri'
$result = Invoke-RestMethod -Method Post -Uri $request
And if you have header like bearer token add -Headers $headers
$headers = #{
'Authorization' = 'bearer HERE_BEARER_TOKEN'
}
Turns out, after quite a bit of back and forth and with an external answer I found out the URL had to be encoded before I could use it in my code
how to translate this code, this was taken from The DropBox API Explorer but a don't know how to translate it to a powershell code specifically using Invoke-RestMethod or another way, the thing is that i need list the content of a folder store in dropbox, all this using powershell and security token
POST /2/files/list_folder
Host: https://api.dropboxapi.com User-Agent: api-explorer-client Authorization: Bearer dropbox_token
Content-Type: application/json
{
"path": "/documentos"
}
Note to Asker: This question could be considered low quality as there appears to be little to no research effort. I'm going to leave an answer because it's a fairly simple question. However, questions should avoid asking "Convert this to that language," or "What's the code for a program that does such and such" (or really any other question) without showing a research effort or an attempt to answer your own question.

REST API's are easy to work with in PowerShell. You just need to pass an ordered hash table containing the headers and a string containing the body. If the body is a json string, which appears to be the case, you can create an ordered hash table and pipe it to ConvertTo-Json to produce the string.
Use the following:
$BaseAPIPath = "https://replaceWithDropboxBaseApi.com/"
$headers = [ordered]#{
"Host" = "https://api.dropboxapi.com"
"User-Agent" = "api-explorer-client"
"Authorization" = "Bearer dropbox_token"
"Content-Type" = "application/json"
}
$body = [ordered]#{
"path" = "/documentos"
} | ConvertTo-Json
$result = Invoke-RestMethod -Method Post -Header $headers -Body $body -Uri "$BaseAPIPath/2/files/list_folder"
You will need to replace $BaseAPIPath with the path to the dropbox api (as it was not provided in your question).
See Invoke-RestMethod
Pretty straightforward question. Posting with:
Invoke-WebRequest -Uri http://www.myWebsite.com/extension -Method POST -Body $myLocalFile
How can I add the "--include" cURL tag to this POST request so I get more information back from the server?
According to the cURL documentation, --include does the following:
(HTTP) Include the HTTP-header in the output. The HTTP-header includes things like server-name, date of the document, HTTP-version and more...
Invoke-WebRequest returns a HtmlWebResponseObject object, and one of the properties of the object is called Headers. That object is a hashtable containing the HTTP headers that came along with the HTTP response, and you can select that collection & look at the contents easily.
$Headers = Invoke-WebRequest -Uri http://www.myWebsite.com/extension -Method POST -Body $myLocalFile |
Select-object -expandproperty Headers
Or, if you need to capture the whole response & pick through it:
$Response = Invoke-WebRequest -Uri http://www.myWebsite.com/extension -Method POST -Body $myLocalFile;
$Response.headers;
I'm trying to write a program that deletes files from a specific device. The device has a REST API and I can access it from the CLI without any problems.
For example if I write this in the CLI, it works :
$clip="test.mov"
$ClipsURL="http://123.45.67.89/clips"
$ClipToDelete=#{action="delete";clipname=$clip}
Invoke-RestMethod -Uri $ClipsURL -Body $ClipToDelete -Method Post -ContentType "application/x-www-form-urlencoded"
I can play around with the $ClipToDelete parameter (changing the value of $clip) and it works every time.
Now when I put that in a loop (in my main script) it works the first time, and times out next.
foreach($clip in $ListClips) {
$clip="test.mov"
$ClipsURL="http://123.45.67.89/clips"
$ClipToDelete=#{action="delete";clipname=$clip}
Invoke-RestMethod -Uri $ClipsURL -Body $ClipToDelete -Method Post -ContentType "application/x-www-form-urlencoded"
}
While debuging I can clearly see that all the values passed as parameters to Invoke-RestMethod are correct (the URL & Body are correct).
My first impression is that I should probably close the session (if that makes any sense) before trying to Post again.
I tried adding a SessionVariable parameter to the command but it didnt change a thing
Does anyone already know how to close a web sesion left open (with the new Invoke-RestMethod command) ? Or does anyone think that the issue lies elsewhere ?
Thank you.
I had faced similar issues while invoking REST APIs from AirWatch.
Evidently the bug has been filed for POST & DELETE methods below:
https://connect.microsoft.com/PowerShell/feedback/details/836732/tcp-connection-hanging-in-close-wait-when-using-invoke-restmethod-with-put-or-delete
But I did face this issue intermittently with GET requests too, I documented the workarounds I had to use in the below TechNet Wiki article, Maybe you can try those and improve it if you find something extra :
http://social.technet.microsoft.com/wiki/contents/articles/29863.powershell-rest-api-invoke-restmethod-gotcha.aspx
foreach($clip in $ListClips) {
$clip="test.mov"
$ClipsURL="http://123.45.67.89/clips"
$ClipToDelete=#{action="delete";clipname=$clip}
Invoke-RestMethod -Uri $ClipsURL -Body $ClipToDelete -Method Post -ContentType "application/x-www-form-urlencoded"
}
In the second line you are overriding the current value with "text.mov".
If it's not a typo error, it could be that you delete the object the first time and you receive timeouts when trying to delete it again (it depends of course on the server-side implementation)
