Webhooks not posting to Slack

[JasonF]

We have mulitple webhooks we are using to post to various slack channels.  They were all working fine, then suddenly they all stopped working.  No admin change that i can see on our JIRA Server.  When i enable Debug/Trace logging for webhooks, the post is logged, but nothing is being sent to slack.

I also tried using modifying the URL and sending to requestb.in and still nothing.  I then setup the exact same webhook in our stage environment and it worked w/out any issues.  Is there any kind of known issue with WebHooks where they just stop firing?  I see at one point there was an issue that was fixed in 6.4 (which is the version we're running).

Anyway, I would love to know if anyone else has seen this, and if so if there is any kind of known workaround.  The ONLY log i get when i enable trace logging for the webhook, is that it shows up in the log.  But i don't see any WARNs/ERRORs etc...

Thanks!

I have the same question. The webhook posting.But not sent out to third part server. Is there a possibility that the thread pool overflows for webhook? there is some warning in log catalina.out

Hi Jason,

This is not an answer to your question. Our company will be using SLACK very soon and our team is researching options for integrating JIRA with Slack. JIRA is installed on a server and 6.4 is the version we use.

Could you please give us some insight on how webhook can be used to establish the integration.

Typical use case would be to post updates on Issue operations in a Slack Channel.

Appreciate your time. Thank you.

Hey Pavan,

Slack provides Webhook integration with JIRA out of the box.  There are also a number of bots you can use to accomplish the same thing (in some cases with more functionality).  When you add the integration from slack, it will generate the URL for you to use for the Webhook.  You can add that to JIRA via System->Webhooks and supply the JQL Filter and update events.  

The out of the box integration is limited to transition events, which you define on the slack side.  What that means is, "issue updated" events will only notify slack if the update is a transition between statuses that you have defined in your Slack configuration for the webhook.

You'll also need a webhook for each channel you want to receive notification in, and you must be a JIRA admin to add the webhook on the JIRA side.  We setup a wiki page that uses behind the scenes admin auth so users could add their own Webhooks w/out being JIRA admins.

Hope this helps!

Jason, 

Did you ever figure out what was going on? I am having the same problem and narrowed it down to something in the JQL on the webhook. We were querying on a status change and that seems to not be working anymore.
