Connect Claude & ChatGPT to Luma

Ask your AI who has signed up for your next event, to approve people on the waitlist, or to set up a new event in Luma. It can create and update events, ticket types and coupons, add and approve guests, and send invites and messages to guests. It also works with your calendar's contacts and tags.

Try asking

  • “Who is registered for Thursday's meetup, and who is still pending?”

    The AI finds the event and lists its guests by approval status, such as approved, pending approval and waitlist.

  • “Create an event on 14 November at 17:00 Copenhagen time with room for 40 people.”

    It creates the event with name, start time, time zone and capacity. A description, location or meeting link can go in the same step.

  • “Approve everyone on the waitlist for the workshop.”

    It lists the waitlisted guests and changes each one's status to approved, with or without a confirmation email.

What your AI can do

Events and tickets

Create, look up and update events, and add ticket types, paid prices and discount coupons.

Guests and invitations

List and read guests, add guests, approve, decline or waitlist them, and send invites and messages.

Contacts and tags

Search your calendar's contacts, import new ones and group them with tags.

  • “Add a paid ticket at 150 DKK and an early-bird coupon.”

    It creates a paid ticket type with price and currency, and a discount coupon with the code you choose.

  • “Tell all guests that doors open at 18:30.”

    It sends a message to the event's guests with your text. This emails every guest, so you can require approval first.

  • “Tag everyone who came to last month's event as alumni.”

    It reads the event's guests and applies the contact tag to them in your calendar's contacts.

Questions

What can the AI do in Luma?

The AI can read your calendar, events, guests, ticket types, coupons, sent messages, contacts and tags. It can create and update events, add ticket types and coupons, add co-hosts, add guests and change their status, send invites and messages to guests, and import and tag contacts.

Does the AI see my Luma API key?

No. Your Luma API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Sending invites and messages emails real people, and declining a guest can refund a paid ticket. These actions can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Luma account with Luma Plus, since Luma API keys require it.

Which Luma calendar does the AI work with?

The calendar the API key was created on. Each Luma key only works for one calendar, so the AI sees that calendar's events, guests and contacts. To work with a different calendar, generate a key on that calendar.
