Alerts API - Close Alert

[Robert Williams]

I've made a few successful API calls using the same integration key (Get Alerts, Update Description, Add Tag), but while trying to CLOSE ALERT, I get "The remote server returned an error: (400) Bad Request"

Any idea what I could be missing here?

<SNIP>

PS C:\> $closeAlertURL
https://api.opsgenie.com/v2/alerts/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx-xxxxxxxxxxxxx/close

PS C:\> Invoke-RestMethod -Method POST -Uri $closeAlertURL -Headers $global:OpsGenieAPIHeader

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

I figured out the problem.

Even though I'm not using any of the OPTIONAL fields in the JSON body, I MUST have an empty JSON body passed with the request.

Here's what worked for me:

<SNIP>

PS C:\Windows\System32> $closeAlertURL
https://api.opsgenie.com/v2/alerts/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx-xxxxxxxxxxxxx/close

PS C:\> $post_message = @{}
$post_message_JSON = $post_message | ConvertTo-Json

PS C:\> Invoke-RestMethod -Method POST -Uri $closeAlertURL -Headers $global:OpsGenieAPIHeader -Body $post_message_JSON

</SNIP>
