## 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.
