Introducing Reservation Automations

Reservation Automations — A Low-Code Way to Grant Access and Control Climate

Today we’re releasing Reservation Automations — a low-code way to program locks and thermostats based on guest reservation data, without the need for you to write custom device logic. Send Seam your reservation data, and we handle the rest.

In the past, developers had to use the Seam Devices API and build complex workflows to manage access and climate — issuing keys at check-in, updating settings mid-stay, and revoking access at checkout.

Reservation Automations replace that effort by syncing reservation and guest data directly with your access and climate systems. Built for short-term bookings — including hotel stays, gym classes, co-working rooms, and event rentals — Reservation Automations ensure device settings activate only during the booked time.

Automations built around the guest journey

Reservation Automations run off the same timeline your guests do. They listen for reservation events — reservation start, updates, and end — and apply the right device settings automatically.

At check-in: keys are issued, spaces unlock, and thermostats adjust to the right preset.
During the stay: if reservation times change or guest details are updated, access and climate settings will adjust in real time.
At checkout: access is revoked, devices reset, and credentials are cleared.

By syncing live reservation and guest data with your access and climate systems, Reservation Automations ensure that device behavior always matches the booking schedule.

How it works

Enable Reservation Automations in Seam Console, then send reservation data with the push_data endpoint. Each reservation includes a unique reservation_key, which Seam uses to create, update, or remove device settings for the booked time. Webhooks notify you when access is issued, updated, or revoked, and the optional delete_data endpoint lets you roll back settings immediately if a booking is canceled or ends early.

2025.09.15 Changelog

New

New events for Access Grants: We now send the access_method.reissued event when the code changes for an Access Method. We also send access_grant.access_times_changed when the starts_at or ends_at time on an Access Grant is changed.
Warnings for deleted Access Grants: We now set a being_deleted warning for access_grant and access_method that are in the process of being deleted.
Search for Instant Keys by URL: Often, you only have the the instant keys url, not the ID. Now you can retrieve instant keys by url by just adding the filter param instant_key_url, like this: /instant_keys/get?instant_key_url=[URL].
Customer data deletion: Users can now permanently delete the data pushed to Seam for a customer using /customers/push_data.

Fixes

Improved Salto KS API reliability: Because Salto KS accesses tokens have relatively short lifetimes and must be refreshed often even before expiration, Seam will now refresh the token frequently to help ensure uninterrupted service.
