Questions

What can the AI do in 4.events?

It can list and read events, ticket types, activities, certificates, attendees and check-in records. It can create events, register attendees with a ticket category or coupon, sign attendees up for activities, remove attendees and send an attendee an email.

Does the AI see my 4.events credentials?

No. Your 4.events credentials are encrypted at rest and never shown to the AI. After you save them, they are 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. Emailing an attendee sends the message right away, and removing an attendee takes them off the event. Both 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 4.events account.

Where do I get a 4.events API token?

4.events does not publish where the client API token is found. Look in your 4.events panel first. If it is not there, ask 4.events support at [email protected] for an API client token, then paste it into HeyMyApps.
