Use OAuth 2.0 with PKCE, device flows for limited interfaces, and short-lived tokens refreshed securely, so you never sacrifice safety for convenience. Keep requested scopes minimal and comprehensible, with clear explanations that build confidence. When you add a new provider, show exactly what is accessed, why it matters, and how to revoke quickly without anxiety or hidden consequences.
Create a canonical schema that normalizes titles, times, attendees, locations, notes, and recurrence rules across CalDAV, Google Calendar, Exchange, Todoist, and more. Map differences explicitly, preserve source identifiers, and store deltas for safe conflict resolution. This translation layer prevents brittle assumptions, enables reliable sync, and makes future connectors significantly easier to implement and maintain without surprises.
Build connectors that retry with exponential backoff, respect provider rate limits, and record auditable logs for every sync operation. Queue tasks idempotently to avoid duplicates after retries. When errors occur, explain them plainly and propose one-click fixes. Reliability earns habit-forming trust, so people feel comfortable delegating scheduling, reminders, and consolidations to your dashboard every single day.
