Invoke-WebRequest Bad Request using Rest API

Question

I'm trying to get the rawcontent using jira rest api using powershell.

(Invoke-WebRequest -credentials get-credential "https://name.jira.com/rest/api/2/search?jql=project%20%3D%20PPM%20AND%20status%20%3D%20%22Waiting%20Approval%22&fields=key").rawcontent

However, after running this script I get Bad Request even when I enter my credentials after getting prompted

Invoke-WebRequest : The remote server returned an error: (400) Bad Request.
At line:1 char:2
+ (Invoke-WebRequest -Credential get-credential "https://solutions.frae ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke
-WebRequest], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWe
bRequestCommand

Has anyone encountered this before? The pretty sure the account I used is correct as I used it to login to jira but it doesn't work when I run this script. Main reason for creating this script is I want to get the output of the Issue Keys so I can use it as the parameters for the other script I used.

Hi,

Sorry to kick a two year old post. Hopefully you got your answer by now... but since this is pretty high on the most view yet unanswered questions, it's a slow day, and rawcontent had me curious... so here goes:

400 Bad Request means Atlassian doesn't like the way your call is formatted. If it were your credentials, it would definitely return 401 Unauthorized.

From what I can tell, you're missing a few things Atlassian is expecting. First is the Method... should be Get in this case. Your are also missing a couple Headers: Accept and Authorization (which should replace your -Credential tag)... You can't just pass PSCredentials. You need to use a header to tell them you're using Basic auth and you'll need to encode the values as Base64... and use api version 3...

Give this a go:

$cred = Get-Credential
$Base64Cred = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $cred.GetNetworkCredential().UserName,$cred.GetNetworkCredential().Password)))
$server = 'https://yourinstance.atlassian.net'
$jql = "Project = `"TEST Project`""
#remember to place a ` in front of all " characters

$responce = Invoke-WebRequest "$server/rest/api/3/search?jql=$jql" -Headers @{"Authorization" = "Basic $Base64Cred"; "Accept" = "application/json"} -Method 'Get'
$responce.RawContent
