You decide, all the way

Changes happen on your real page, so Claude asks first.

  • Preview first

    Every change starts as a preview. Claude shows you what will happen and waits for your yes.

  • Your role sets the limit

    Claude can only do what you can do in Connect, and only on the pages you picked.

  • Money stays in Connect

    Bank accounts, payouts and fees can never be changed through Claude.

  • Disconnect any time

    The connection ends after 30 days without use, and a year after you connected at the latest. You can also end it yourself.

    Open AI settings

Using another AI?

The plugin is the easiest way in Claude. The connection also works without it, and in other AI apps.

Add the connection directly

  1. 1In Claude, open Customize and then Connectors.
  2. 2Press the plus and choose Add custom connector.
  3. 3Name it Happenings Connect and paste the address below.

Under the hood

Everything runs through the Happenings page CLI, the same commands page admins use. That gives Claude the whole toolbox with only four tools.

  • hap_help

    Shows the commands and their options. Runs nothing.

  • hap_read

    Reads events, sales, orders, members and more. It changes nothing, and it refuses any command that would.

  • hap_run

    Makes a change on the page, like creating or publishing an event. It previews first, and Claude asks you before each one.

  • media_upload_widget

    Opens an upload box for a photo, poster or logo, because Claude cannot pass a chat attachment on.

If something gets stuck

I can't see Plugins in Claude
Plugins come with Claude's paid plans, Pro, Max, Team and Enterprise. On a Team or Enterprise account, your admin can decide which plugins you may install.
My computer unzipped the file
Download it again and upload happenings-plugin.zip as it is. Some browsers unzip downloads automatically, so check that the file ends in .zip.
The plugin is installed, but Claude can't see Happenings
Open the plugin, go to Connectors and check that Happenings Connect is connected. Then start a new chat.
A page is missing
Claude only sees the pages you ticked. Disconnect in Connect, connect again and tick the page.
Claude says it was refused
Your role on that page does not allow it. Ask a page admin for the role, or do it in Connect.
Claude asks me to sign in again
The connection ended, because it went unused for 30 days, you signed out everywhere, or it was disconnected. Sign in and pick your pages again.
Claude keeps asking for permission
Under Customize and Connectors you can set Happenings Connect to Always allow. That only skips Claude's own question about using a tool. Happenings still previews every change first, and the plugin tells Claude to wait for your yes. Want an extra safety net? Leave hap_run on ask.

Happenings Group A/S runs the connection. Claude only gets what you ask for, from the pages you picked, and every command it runs is logged. Read our privacy policy
