What you can connect

Four ways to put the API to work

An appointment alone rarely tells the whole story. The API extends your scheduling platform across the systems and partners your business already runs on.

Workflow management

Not every scheduling scenario is linear. Sequence and structure API calls to deliver the exact booking experience your business needs.

Pro tip: Engage our API consultants early in the design process — we’ve spent many hours helping clients sequence and structure their calls.

Integrations

Share data between scheduling and the rest of your stack — ERP, POS, ATS, EHR, CRM and more — for a complete picture of every customer.

Pro tip: Use Webhook / Callout capabilities to kick off your middleware on an event — like an appointment being created or updated.

Data analysis

Extract the critical data behind your business decisions. Built-in search and parameters let you scope exactly the range you need.

Pro tip: Use start/end date parameters to limit response volume; filter by updated or created to pull only what’s changed since a timestamp.

3rd-party connections

Extend the platform to your important partner networks and let them implement scheduling into your facilities — on your terms.

Pro tip: Give each partner their own API key — share thoughtfully. Restrict access by endpoint, and even add a partner code on the appointment for tracking purposes.
Enterprise-grade by design

A RESTful API that respects your rules

Requests go to specific URLs over HTTP; responses come back as XML, JSON, or a JSONP callback. Every call honors the configurations, settings, and rules defined in your administrative interface.

Full CRUD endpoints

Create, Read, Update, and Delete across a flexible set of endpoints for appointments, customers, locations, services and more.

Flexible output formats

Get responses as JSON, XML, or a JSONP callback — whichever fits the system you’re integrating with.

Webhooks & Callouts

Fire on Customer (Create / Update / Delete) and Appointment (Create / Update) events to drive notifications and middleware.

Security & access control

HTTPS communication, basic authentication, endpoint restrictions, read-only keys, and time-boxed key expiration.

Performance at scale

Response times align with the industry standard of under two seconds, even across high-volume enterprise workloads.

Your brand, preserved

Build virtually any user experience — including mobile — while preserving the look, feel, and rules of your brand.

One API, many workflows

“In 10+ years on DaySmart Appointments, we’d never had data to drive the business. In the last year we built our data-capture pipelines on the API — and now we make decisions centrally and quickly.”
