Calendar engineering guide

Where a scheduling API removes real workflow friction

Scheduling infrastructure is most useful when it combines account connection, multi-calendar availability, booking policy, provider events, and change handling inside the product where work begins.

Research surface only. This guide documents architecture and evaluation criteria; it does not describe a released DewEngine connector.
01
In-product flow

Keep booking connected to the work record

Create candidate slots from the responsible user's calendars, store the resulting booking against the CRM, support, recruiting, or service record, and use provider event IDs for every later update.

02
Availability policy

Represent more than open gaps

A usable API needs working hours, buffer time, minimum notice, maximum horizon, meeting types, round-robin ownership, capacity, rooms or resources, and explicit time-zone behavior.

  • Per-user and team rules
  • Multi-calendar conflict set
  • Resource and room availability
  • Holiday and override schedule
03
Automation

Trigger from confirmed provider state

Use event-created, changed, cancelled, and attendee-response evidence to update workflows. Do not start a downstream process merely because the browser displayed a confirmation before provider creation completed.

04
Measurement

Measure reliability before claiming productivity

Track booking completion, conflict rate, provider create latency, sync lag, reschedule success, and reconnect interruptions. Productivity is an outcome to test, not a property guaranteed by adding an API.

  • Booking success rate
  • Double-booking incidents
  • Median confirmation time
  • Calendar health and sync lag
Questions

Before you build.

Does a scheduling API automatically improve productivity?+

No. It can remove manual coordination, but the outcome depends on accurate availability, sensible policy, reliable event creation, and a workflow users actually adopt.

Should all event details be read to calculate availability?+

Usually no. Provider free/busy or schedule endpoints can minimize exposed details when only occupied intervals are required.

Can I use DewEngine's calendar connectors today?+

Not as released connectors. Google Calendar has one feature-flagged development method, calendar.event.create, plus list/get for DewEngine-confirmed creates and the resulting canonical creation event. Provider calendar reads and sync, update/delete, availability, recurrence, watches, and Microsoft Graph Calendar remain planned. The implemented slice has only local fake-provider evidence, not real-account or production conformance.
