MS Team webhook works for some users, doesn't work for others

Guy Incognito_79x5fx

Hi all,

I use Scriptrunner to send MS Teams (and Slack) notifications when some issues are transitioned. The problem is, that MS Teams notifications only work for certain Jira(/Microsoft) users (e.g. mine), and not for others.

When the notification fails, I get a 400 error.

Here's my Scriptrunner groovy code:

def notificationChannel = "https://XXXXXXXXXX.webhook.office.com/webhookb2/XXXXXXXX/IncomingWebhook/YYYYYYYYYYY/ZZZZZZZZZZZZZZ"
try {
   def post = new URL(notificationChannel).openConnection() as HttpURLConnection
   def teamsMessage = "{'text':'"+notificationMessage+"'}"
   post.setRequestMethod("POST")
   post.setDoOutput(true)
   post.setRequestProperty("Accept", 'application/json')
   post.setRequestProperty("Content-Type", "application/json")
   post.getOutputStream().write(teamsMessage.getBytes("UTF-8"))
   def postRC = post.getResponseCode()
   if (!postRC.equals(200)) {
      throw post.getInputStream().getText()
   }
} catch (err) {
   SlackUtil.message("slack_connector",
      Constants.ERROR_NOTIFICATION_CHANNEL,
      "<!channel>\n"+err.getMessage()
   )
}

When it fails, the returned error is:

Server returned HTTP response code: 400 for URL: https://XXXXXXXXXX.webhook.office.com/webhookb2/XXXXXXXX/IncomingWebhook/YYYYYYYYYYY/ZZZZZZZZZZZZZZ

 If I open the same issue with my Jira users, and execute the same transition, the notification goes fine.

Any hints?

Thanks in advance!

Hi @Guy Incognito

Just to check, have you confirmed whether all the users receiving the MS Team notification have the required permission or exist in your instance?

I am asking this because if you look through the Slack API, the HTTP 400 error message is returned only when there is an invalid payload or the user is not found.

Also, I suggest taking a look at this Adaptavist Library example of how a Custom Notification is sent to Slack.

I am looking forward to your feedback and clarification.

Thank you and Kind regards,

Ram
