Connect KlangCity with your tools

Automations connect KlangCity with n8n, Make, Zapier or your own systems. KlangCity reports events to your address, and your workflows create tasks or read data through the API.

• Plan: from Pro
• For: owners and admins
• Signature: HMAC-SHA256

What you can do with automations

Webhooks in a minute

“+ New connection”: enter the address, choose the events, done. “Send test” checks the connection right away.

Signed

Every message carries an HMAC-SHA256 signature and a timestamp. That is how your system checks that it comes from KlangCity.

Delivery with retries

If your system does not answer, KlangCity tries again after 1, 5 and 30 minutes and after 2 hours. “Recent deliveries” shows status and errors.

One key for the API

The key is shown once and only stored as a hash. “Rotate key” makes the old one invalid immediately.

Create tasks

Title, description, status, priority, due date, checklist, assignee and milestone in one call.

Read data

Tasks of a project, stock levels, the next agenda, files from Drive and meeting minutes as PDF.

Orders and bookings

Deliver orders for material planning and write bookings from booking systems into the calendar.

No loops

Tasks created through the API report with the sender “API”. That way you can filter them out in n8n.

The ten events

• Task created
• Status changed
• Task done
• Task assigned
• Task deleted
• Task archived
• Meeting minutes ready
• Inventory: material below minimum stock
• Inventory: material requirement from an order
• Constitution changed

At a glance: plan, permissions, data

As implemented in KlangCity, as of October 2026.

• Plan: From Pro.
• Who can do what: Owners and admins manage connections and keys. Members and guests do not see the page.
• Stability: The /api/v1 interface stays backward compatible for at least 24 months (terms, section 5.6).
• Log: New, switched and deleted connections and new keys appear in the admin log. Deliveries are deleted after 30 days.
• Data: Messages about tasks contain the email address of the assignee.
• AI: If a task arrives without a group, the AI assigns it based on its title and description. You can switch this off with the AI master switch.

Works well with

• Inventory: Report low stock and material requirements, read stock levels.
• File storage (Drive): Read folders and files.
• Meetings: “Meeting minutes ready” and the minutes as PDF.

Good to know

• There is one key per organisation. You decide which areas it may use, for example only writing bookings into the calendar.
• You cannot change or delete tasks through the API.
• No events for chat, comments and the calendar.
• Paused connections do not catch up on missed events.

We would rather tell you up front what is missing. What comes next is on the roadmap.
