ChatGPT uses a small private web connection to ask Hostfully read-only questions. You own that connection; it only talks to Hostfully when you ask ChatGPT something.
Connecting Hostfully to ChatGPT
Yes, when you keep it read-only. Your Hostfully API key stays in a private connection you control, not inside ChatGPT, and this setup only reads data; it cannot create, change, or cancel reservations. Remove the ChatGPT app and delete the private connection to revoke access at any time.
Three things: a paid ChatGPT plan with Developer mode (or custom MCP connectors) enabled, Hostfully admin access to obtain Hostfully API key, and a free Cloudflare account for the private connection.
No. This guide sets up a read-only connection, so ChatGPT can answer questions about your Hostfully bookings, guests, and calendar but cannot modify anything.
Plan on about 45-90 minutes if your Hostfully API key is ready. It can take longer when Hostfully requires API approval, partner access, or workspace admin approval before ChatGPT can scan the connector.
Most common Hostfully issue: the key reads properties but not guest reservation details. Guidebook and PMS permissions may not be identical.
Have these ready.
Budget about an hour for connector setup once credentials are ready. Add more time if you need API approval, partner access, or workspace admin approval.
Keep the first version boring and read-only.
Connect Hostfully to ChatGPT in 4 steps.
Get your Hostfully credentials
- Open Hostfully with admin access.
- Create or copy an API key that can read bookings, guests, and properties.
- Paste the key into the setup form.
Set up the private connection
- Use a private Cloudflare Worker or managed setup path so PMS credentials stay outside ChatGPT.
- Paste your Hostfully API key into the prompted fields.
- Deploy the private connection and open the generated health page.
- Confirm it says Connected to Hostfully before continuing.
Add it to ChatGPT
- Open ChatGPT settings.
- Go to Apps, open Advanced settings, and enable Developer mode.
- Create a custom app from the remote server URL shown on the health page.
- Complete the OAuth authorization screen.
Try operational prompts
- Open a new chat and select the app from Developer mode.
- Start with arrivals, departures, missing guest details, and occupancy questions.
Start with operational questions, not vague chatbot prompts.
Expected result: ChatGPT should answer with specific Hostfully records: property names, reservation dates, guest fields it is allowed to read, and a clear note when data is missing.
Good for one property. Thin for a real portfolio.
ChatGPT can answer Hostfully questions. Axelrod turns the same booking data into morning briefs, guest-message drafts, cleaner handoffs, pricing nudges, and an approval queue across your stack.

Hostfully issues first, generic OAuth issues second.
Guidebook and PMS permissions may not be identical.
If properties are grouped by agency/team, confirm the API key covers the right agency.
Most common Hostfully issue: the key reads properties but not guest reservation details.
Developer mode is missing: confirm the ChatGPT account or workspace can create custom apps, and ask the workspace admin if the option is hidden.
OAuth popup blocked: allow popups for ChatGPT, then reconnect the app.
The app returns empty results: check that the PMS user or token can read all properties, reservations, and guests.
The app returns unauthorized: rotate the PMS credential, redeploy the private connection, then reconnect ChatGPT.
