Hi I get this error with my powershell script. How can I fix so the request goes through? 

Invoke-RestMethod : The remote server returned an error: (400) Bad Request.

Here's the script:

[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12 



$APIKey = 'K58O3NlKuIMP2ZFh7BtY'

$EncodedCredentials = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $APIKey,$null)))

$HTTPHeaders = @{}

$HTTPHeaders.Add('Authorization', ("Basic {0}" -f $EncodedCredentials))

$HTTPHeaders.Add('Content-Type', 'application/json')



$URL = 'https://bcservices.freshservice.com/api/v2/tickets'



##########

$TicketAttributes = @{}

$TicketAttributes.Add('requester_id', '15000000000')

$TicketAttributes.Add('email', 'example_email@email.com')

$TicketAttributes.Add('phone', '555-555-5555')

$TicketAttributes.Add('status', '2')

$TicketAttributes.Add('priority', '2')

$TicketAttributes.Add('source', '2')

$TicketAttributes.Add('type', 'incident')

$TicketAttributes = @{'ticket' = $TicketAttributes}

$JSON = ($TicketAttributes | ConvertTo-Json) 



# Invoke the request

Invoke-RestMethod -Method POST -Uri $URL -Headers $HTTPHeaders -Body $JSON

I was having this same problem and I just figured it out! Unfortunately PowerShell isn't too friendly when it comes to troubleshooting REST errors, so I installed Ubuntu from the Windows Store so that I could get bash and curl.


When I ran the sample curl command from this page for API v2, it failed with this little message at the end:

{"description":"Validation failed","errors":[{"field":"group_id","message":"It should be of type Positive Integer","code":"missing_field"}]}

Because we are set up with multiple agent groups, apparently the group_id field is mandatory when creating a ticket through the API. So I was able to modify my PowerShell to the below code and was able to POST a new ticket:

# Global Variables



$APIKey = 'your-api-key-here'

$EncodedCredentials = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $APIKey,$null)))

$HTTPHeaders = @{}

$HTTPHeaders.Add('Authorization', ("Basic {0}" -f $EncodedCredentials))

$HTTPHeaders.Add('Content-Type', 'application/json')

$URL = 'https://your-subdomain-here.freshservice.com/api/v2/tickets'



# Ticket Attributes



$TicketAttributes = @{}

$TicketAttributes.Add('email' , 'requester@contoso.com')

$TicketAttributes.Add('subject' , 'Ticket from PowerShell')

$TicketAttributes.Add('description' , 'This ticket was successfully created from PowerShell.')

$TicketAttributes.Add('status' , 2)

$TicketAttributes.Add('priority' , 2)

$TicketAttributes.Add('group_id' , 0000)



# Convert Attributes and POST



$JSON = $TicketAttributes | ConvertTo-Json 

Invoke-RestMethod -Method POST -Uri $URL -Headers $HTTPHeaders -Body $JSON
