Before you call either

Apiroc Unified Calendar API

  1. Send the key in the x-api-key header from a server, never a browser
  2. Call api.apiroc.com, since the SDK's old default host was api.onecalunified.com
  3. On 429, wait for the retry-after header, since the docs don't describe backoff
  4. Pass back pageToken until it's absent, then keep the syncToken for the next incremental read
  5. Dedupe webhooks on svix-id, since Svix retries deliveries

Cozi Family Organizer

  1. Use official read-only feeds for calendar visibility.
  2. Make edits in the originating calendar and allow for the refresh delay.
