Any way to automatically sync Slack thread to Jira issue?

[Alastair Adams]

Hi there,

We've set up a Slack channel in which issues can be submitted into a space via the Jira Cloud integration /jira create. When an issue is submitted, it appears in the channel - but in order for comments from the Slack thread/Jira to sync up on both sides, someone has to manually click the three dots at the right of the issue in Slack and click "sync thread". Is there any way to enable this syncing automatically and not require this to be manually clicked?

Would appreciate help! Thanks.

You have to create the Jira Work Item from within Slack using the Jira Cloud for Slack App. That is the most efficient way to automatically sync the threaded comments between Slack and Jira. You can still sync other threads after a Jira Work Item exists, but for the use case you asked about, you need to create the Jira Work Item directly in Slack.

There’s no built‑in Jira Cloud feature that keeps a Slack thread and a Jira issue in sync automatically.

JSM projects do have Slack Assist, which can sync comments with Slack threads — but it only works inside Service Management projects. For Software, Business, and other project types, there is no native two‑way sync.

If you need this behavior outside JSM, the only option is to use an app that listens to Slack events and mirrors them into Jira. This requires handling Slack message events, storing the thread → issue mapping, and posting updates through the Jira REST API.

I’ve built an app that implements this workflow for any Jira Cloud project type. It keeps Slack thread replies and Jira comments aligned automatically and also supports optional features like changing issue status via emoji reactions.

@timtim , please, can you not share AI-generated responses here? Here is an explicit statement from Atlassian support that there is in fact "native Slack -> Jira sync".  I have invested time and effort in answering this, so please, do not dismiss my correct response below with false AI-generated claims based on outdated information, I'd appreciate. 

 

G'day Svetlin,

Greetings!! Hope you are doing well.

Thanks for contacting Atlassian Cloud Support Team! My name is Varun, and I'll be assisting you with this case.

From the issue description, I understand you've confirmed that native Slack thread synchronisation is now available as part of the Jira Cloud for Slack integration, and you're looking for validation of that statement.

Please feel free to correct me if my understanding is incorrect.

first, thank you for your valuable contribution to the community ⭐

You are absolutely correct! Atlassian introduced native thread synchronisation as part of the Jira Cloud for Slack integration. The feature rolled out progressively starting around January 2025, and the official documentation confirms the capability here

Sync your Slack threads with Jira work items
Regarding the feature request JRACLOUD-97607, one tackles a slightly different gap. The native sync feature today works when you either:

Create a work item directly from Slack (auto-syncs), or
Manually select "Sync with thread" on a Jira link preview card. (screenshot added)
The FR specifically requests that thread sync also be triggered automatically so users wouldn't need to manually click "Sync thread" each time a notification appears. It's a UX enhancement on top of the existing native capability, not a request for the feature itself.

Let me know if this addresses your question.

Kind regards,
Senior Support Engineer | Jira Cloud Support

I also appreciate the Marketplace app ad, nothing against that, just let's not mislead and have a clear record of what is what.

@Svetlin 

Thanks for your reply, that’s an important point.

I am aware of that feature, but it isn't fully "automatic", which is why I didn't mention it in my initial response. You received the correct answer from support: for synchronization to work, one of the following conditions must be met:
1. The task must be created from Slack (though this didn't work for me; I still have to click "Sync thread").
2. You must manually click "Sync thread" for each task you want to synchronize.

The original question was: "Is there any way to enable this syncing automatically and not require this to be manually clicked?"

The answer is no, it’s not possible with the current implementation, which is exactly what Atlassian support states.

P.S. I use AI to check my English text since it’s not my native language, not to write the text itself.

A number of older Community answers correctly stated that Jira and Slack could not automatically synchronize an entire Slack thread with a Jira issue. However, Atlassian has since introduced native thread synchronization as part of the Jira Cloud for Slack integration.

The feature began rolling out around January 15, 2025, when Atlassian announced "Sync Slack threads with Jira comments" and started the rollout of the capability.

Today, you can:

Paste a Jira issue link into a Slack conversation and select "Sync thread" from the Jira issue preview card.

Atlassian's current documentation explicitly describes how to sync and unsync Slack threads with Jira work items and confirms that replies in the Slack thread are added as comments on the Jira work item.

One small caveat: January 15, 2025 appears to be the date the rollout was announced/started, not necessarily the date every Jira Cloud site received the feature. Atlassian rolled it out progressively.

I just figured out one of the commenters here has already ref. someone else to that as early as January 2026:

Atlassian also hasn't updated this FR: https://jira.atlassian.com/browse/JRACLOUD-97607

There isn't really a way to do this automatically with /jira create. The process @Dave Buitenhek outlined in his reply (From a Slack message, click More actions → "Create work item from Jira Cloud") is probably your best bet, because it creates the sync automatically.

Alternatively, you'd have to look at third-party apps on either the Atlassian Marketplace or Slack Marketplace. Note that many of them just handle the creation of work items though, and won't keep things in sync. Appfire and Unito are two examples of tools that actually keep things in sync.
