HackMD Webhooks are live 🪝

No dark-mode styles — this email renders the same in a dark client.

HackMD now sends a signed event to your endpoint when a note or folder changes, so your tools stop asking.

Webhooks: HackMD knocks when your notes change

Hey nseemre!

Your team's work already lives in HackMD. The tools around it have no idea when any of that changes, so someone pastes the link by hand or a script keeps asking.

Webhooks are live. 🪝

When a note or folder changes, HackMD sends a signed event to a public HTTPS URL you control. Scope it to a whole workspace, or to one folder and its subfolders. The event says what happened and which note or folder it was; your receiver fetches the content from the API when it needs it.

For most people writing in HackMD, nothing changes day to day, and that's the point. The tools your team connects just stop needing a nudge.

If you build those tools, one webhook can replace a polling timer. A small receiver in the middle can carry events to Slack, Discord, GitHub Actions, or your own API, and four ready-made recipes ( https://hackmd.io/@docs/webhooks-recipes ) show how.

💡 Two things to know before you start: Free workspaces get 1 webhook and Prime gets 10, and real deliveries count toward your API quota.

Happy Hacking,

The HackMD Team
