Frequently Asked Questions

What data can Fantastical access via the Contacts API?

Fantastical can access contact data such as names, emails, phones, and basic notes via the Contacts API, within the scope you grant (readonly in this setup). You can read contact lists and retrieve associated tasks and notes, then surface them in Fantastical calendars and reminders. All access respects permission settings and user consent. If you enable more than readonly scope, Fantastical could create or update records as allowed by your authentication.

No heavy coding is required. Use the pre-defined endpoints and triggers to automate data flow. Set up OAuth, configure scopes, and test with sample requests. The UI can guide you through enabling read-only access before enabling writes.

The most used endpoints are GET /contacts/:contactId to fetch details, GET /contacts/ to list, and GET /contacts/:contactId/tasks to pull tasks. For updates, PUT /contacts/:contactId and POST /contacts/ are common.

Use test mode or sandbox, run a few test requests, verify data appears in Fantastical. Check webhooks and OAuth scopes. Monitor logs for errors and rate limits.

Authentication uses OAuth tokens and API keys. Store credentials securely, rotate keys regularly, and limit access by roles. Use the least-privilege principle.

Yes, you can map tags from Contacts to Fantastical tasks or events to help categorize items. Tags flow depends on your app’s data model and how you configure the integration.

Rate limits vary by endpoint; monitor the response headers for quotas and implement retry logic. If you hit limits, reduce frequency or batch requests. Support is available if you need higher quotas.
