Programmatic API to link a Jira (Product Discovery) item to a Slack thread and count linked Slack me

[Pierre PM]

We run an automated feedback pipeline: a bot reads every Slack message and creates/triages Jira Product Discovery Feedback items. Today the official "Jira for Slack" integration can sync a Slack conversation thread to a Jira item and count linked Slack messages as Insights — but only when a human triggers it via @JIRA / the message action. There is no public API for either:

1. creating the Jira↔Slack thread link / "synced thread" programmatically (bot-initiated), and
2. creating JPD Insights via the Jira REST API (JPD Insights have no API — confirmed in the community earlier).

As a result, automated bot-created feedback cannot be officially linked/counted as Insights, so teams that prioritize feedback by insight count lose that signal for bot-ingested items.

Requested: Please provide official APIs so an authenticated app can (a) link a Slack message/thread to a Jira item (equivalent of the Jira-for-Slack "sync thread" / "add message to issue" action), (b) create JPD Insights on an idea/feedback via REST (or GraphQL), and ideally (c) have bot-initiated Slack↔Jira links reflect in both surfaces and produce Insights so automation can count them.

Impact: Any team automating product-discovery intake (support bots, MCP integrations, internal tooling) that wants consistent insight-based prioritization. It would let automation produce the same first-class, countable evidence a human produces with one click today.

(See related community threads: "Is it (or will it be) possible to create Insights in Jira Product Discovery via API or MCP?" (June 2026); "Product Discovery APIs" — migrating via REST works but Insights do not.)
