Since we started using Resos, we have found the flexibility of the product and customer support incredible. It's very user friendly and easy to manage in-house which is a huge plus!
API
Connect Resos to everything else you run
A modern REST API that gives developers programmatic access to your bookings, guests, custom fields, opening hours, and tables. Push reservations in from another channel, pull guest data into your CRM, or wire Resos up to your accounting tool. Whatever your stack already looks like, the API turns Resos into the booking layer that talks to it.
How it works
A clean REST API for the whole stack
Create bookings
Push reservations in programmatically
When a booking comes in from another system, a phone call your tooling logs, or a partner channel you handle separately, post it straight to Resos through the API. The reservation lands on the calendar with the same data and the same rules as any guest-facing booking.
Fetch bookings
Pull reservations into your own tools
Fetch bookings by ID or by date range and feed them into your own dashboards, BI tool, or operations system. Keep the rest of your stack in sync without anyone re-entering data, and run your numbers wherever your team already looks at them.
Guest data
Keep profiles aligned across systems
Read and update guest profiles, custom fields, opening hours, and tables through the API. Sync Resos with your CRM, marketing platform, or loyalty tool so the guest who books on your site is the same record your campaigns and your service team already know.
Documentation
OpenAPI spec and partner support
The API is documented via an OpenAPI 3.0 specification with an interactive reference. Authentication uses private keys and follows modern REST conventions, so any developer can get up and running without a discovery call. Our team is on hand for partners building deeper integrations.

Resos’ reservation system API is the essential middleman that allows your current software systems to communicate with our booking system. This means you can give developers or marketing managers programmatic access to your guest and booking data without doing it manually - a great way to reduce the workload for your team and connect Resos to whatever other tools you already run.
How Resos’ reservation system API works
Resos’ reservation system API is a cloud-based interface that makes it possible for your systems to interact with each other. This means that if, for instance, your restaurant receives a booking via another system, you can make a request to our API which then automatically will register that booking with all the available data.
In other words, our API allows you to receive bookings from the whole spectrum of hungry guests. No matter if they wish to book via the phone, computer, smartphone, or tablet.
Our API is a modern REST API that requires a set of private keys in order to obtain access. It’s fully secure and follows the modern standard for API communication. The API can give you access to all relevant information from Resos such as guest-data, booking-data, or any other data that you might be interested in integrating into another system.
With our API, you will be able to:
- Create bookings programmatically (e.g. when a booking comes in from another system or a phone call your tooling logs).
- Fetch bookings by ID or date range to sync them into your own systems.
- Edit or cancel existing bookings.
- Read and update guest profiles, custom fields, opening hours, and tables.

Once set up properly, Resos will run the whole booking seamlessly. Been trying many softwares and none has reached the level of customization and speed as Resos. And great support too!
The floor view is working very nicely, you can see everything at the same time. Also, it was a very huge upgrade for us, that the guests can easily cancel their booking – it saved us from a lot of no-shows.
