Jira Automation Microsoft Teams Message with Error 400

Hi, I've setup an automation sending a message to microsoft teams when an issue is commented. I followed the instructions in the action details (add connector in teams channel, copy webhook url, paste it into automation action).

When the rule is triggered I get an error:

Error communicating with the API400 - Webhook Bad Request - null or empty eventType

On the other side, if I set up the same webhook communication via Jira system settings -> webhook -> create new webhook and send messages from there, it works.

what am i doing wrong?

Try using a different Connector on MS Teams side called Incoming Webhook.

Hi Martin,

Thanks for your suggestion. I had the same error of Webhook Bad Request - null or empty eventType.

I tried your suggestion and it worked perfectly.




Same problem and same fix worked. Thanks for asking @zaldy parian  and thanks for answering @Martin Ceska 

What should I do if I cannot see this webhook? Does it need to be enabled from somewhere else?

I've tried to follow: Create an Incoming Webhook - Teams | Microsoft Docs

Has anyone encounter similar issue?

Most likely this is caused by trying to send the request to a JIRA Cloud connector hook in Teams instead of a (generic) Incoming Webhook connector hook.

Edit: Seems like this was already answered above.

The issue is that JIRA is sending a different JSON response when doing it from a transition , vs those checkboxes.

I hooked up the webhook to a and when I pushed the response along to to MS teams - I got "Webhook Bad Request - null or empty eventType" - which it doesn't have


Only the ones triggered from "created, updated" have this metadata

Has this been investigated further yet as i'm attempted to trigger a webhook into a Microsoft Teams Channel based off a simple JQL query.


I tried to use Incoming Webhook but to no avail, any suggestions?

[Not the answer] I have the same question.

I want to use the automation action and when I use in conjunction with creating new webhook in the way Oliver describes, it does send a message to Teams.  However, all the formatting and message content that I created in automation is not used.
