Gap-night list per property for last-minute revenue follow-up.
Reservation totals split by accommodation and distribution channel.
ChatGPT uses a small private web connection to ask Avantio read-only questions. You own that connection; it only talks to Avantio when you ask ChatGPT something.
Connecting Avantio to ChatGPT
Yes, when you keep it read-only. Your Avantio API username and password 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, Avantio admin access to obtain Avantio API username and password, 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 Avantio bookings, guests, and calendar but cannot modify anything.
Plan on about 45-90 minutes if your Avantio API username and password is ready. It can take longer when Avantio requires API approval, partner access, or workspace admin approval before ChatGPT can scan the connector.
Most common Avantio issue: the connection was attempted before Avantio support activated and issued the API username and password for your account. Avantio API access is not self-service. The username and password are issued by Avantio on request, not generated from a settings page.
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 Avantio to ChatGPT in 4 steps.
Get your Avantio credentials
- Request API access for your account from Avantio via the support portal (support.avantio.com) or the Live Chat inside your Avantio account.
- Avantio's team provisions and sends your API username and password (your API login pair).
- Confirm the credential has read access to reservations, accommodations, and availability before connecting.
Set up the private connection
- Use a private Cloudflare Worker or managed setup path so PMS credentials stay outside ChatGPT.
- Paste your Avantio API username and password into the prompted fields.
- Deploy the private connection and open the generated health page.
- Confirm it says Connected to Avantio 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 Avantio 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 Avantio questions. Axelrod turns the same booking data into morning briefs, guest-message drafts, cleaner handoffs, pricing nudges, and an approval queue across your stack.

Avantio issues first, generic OAuth issues second.
Avantio API access is not self-service. The username and password are issued by Avantio on request, not generated from a settings page.
Some partners label the same provisioned credential an "API key"; if you only received one string, ask Avantio for the matching login so the read connection authenticates.
Most common Avantio issue: the connection was attempted before Avantio support activated and issued the API username and password for your account.
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.
