Change or Cancel Reservations on WhatsApp with Eat App

By Alva Chew 3 min read Updated October 25, 2026

This recipe handles the messages that come after a booking: “can we make it 8.30 instead?”, “we are now 6 people”, “sorry, need to cancel”. AeroChat finds the reservation in Eat App and makes the change. Part of the Eat App integration.

What happens today

Changes arrive by message on the day, often during service. Nobody sees a cancellation until the table is already being held empty. A party that grew from four to six turns up to a table for four.

The flow that works

  1. The guest asks to change or cancel. AeroChat finds their reservation in Eat App by phone number.
  2. For a new time or party size, it checks availability and offers what is free.
  3. It updates the reservation, or cancels it, in Eat App.
  4. It confirms the change in the chat.

The recipe

Copy this into AeroChat

When a guest asks to change or cancel a reservation, find their upcoming reservation in Eat App by phone number. If there is more than one, ask which date. To change the time or party size, check availability in Eat App for the new details. If it is free, update the reservation. If not, offer the two nearest free times, and keep the original booking unless they choose a new one. To cancel, confirm the date and time with them, then cancel the reservation in Eat App. Thank them for letting us know. If a change would make the group larger than 10 (example), hand the conversation to our team. If the booking had a deposit, do not promise a refund. Tell them our team will reply about the deposit and hand over.

What to connect

  • Eat App. The same API key as the reservations recipe, issued by Eat App when you ask for API access.
  • Your cancellation and deposit policy. Upload it to the AeroChat knowledge base.

Using a different system? If it has a public API, it connects to AeroChat the same way: describe what you want, paste in its key, and it runs.

Can’t find your tool? Message us in the chat on this page and we’ll tell you how it connects.

What you still decide

  • How late a guest can change or cancel in chat.
  • Your deposit and refund rules.
  • Which changes always go to a person.

The result to expect

Cancellations free the table as soon as the guest sends them, so you can offer it again. Party size changes reach the floor plan before the guests arrive. Track how many tables are held for guests who do not arrive.
