SimplyBook.me is a cloud appointment scheduling and online booking platform for beauty, wellness, healthcare, fitness, and other service businesses. Its JSON-RPC API is gated behind the paid API Custom Feature—once enabled, an unofficial integration lets you programmatically pull bookings, clients, services, providers, and availability, and push new bookings, edits, cancellations, and client records back into SimplyBook.me.

SimplyBook.me is a cloud-based appointment scheduling and online booking platform for service businesses.

Bookings
/admin/getBookingsRetrieve a filtered list of bookings by date range, service, provider, client, or status, with details available via getBookingDetails.
Bookings
/admin/bookCreate a new booking for a given service (event), provider (unit), client, and time slot; editBook and cancelBooking manage the lifecycle.
Clients

Catalog
/admin/getEventListFetch the catalog of services (events) and service providers (units) configured for the company, including durations and pricing.
Availability
/admin/getStartTimeMatrixReturn available start times and open intervals for a service and provider so external apps can present real-time booking slots.

Yes. API access is gated behind the API Custom Feature, which must be enabled in the admin interface under Custom Features. Once active, the API key is available in its settings and Supergood works against your authenticated company tenant.
It is JSON-RPC 2.0 over HTTPS, with separate login, public, and admin services. Supergood handles the JSON-RPC envelope, token exchange, and method routing so you integrate against normalized objects instead of raw RPC calls.
You call getToken with your company login and API key to receive an access token valid for one hour. Supergood manages token issuance, refresh, and rotation automatically so your integration never has to handle expiry manually.
You can read bookings, clients, services (events), providers (units), availability, and reporting metrics, and write new bookings, edits, cancellations, and client records through the admin service methods.
Yes. Each SimplyBook.me company has its own API key and tenant. Supergood normalizes bookings, clients, and catalog data across companies so multi-location operators integrate once across all of them.
