Connect iCloud Calendar to Hypamoon
Not today. iCloud Calendar has no public API, so there is nothing an adapter can safely build on.
ClosedThe check
Three questions about the API of iCloud Calendar, answered from its own docs.
- Public API docs
- No. Apple publishes no developer API for iCloud Calendar; third-party apps sign in with an app-specific password. Read the docs
- A key you create yourself
- Yes. With two-factor authentication on, you create an app-specific password yourself at account.apple.com. support.apple.com
- Versions or a changelog
- Not confirmed.
- How it signs in
- Apple Account email with an app-specific password, used by calendar apps.
- Webhooks
- No.
- Hosting
- Cloud
What you can do instead
Ask iCloud Calendar whether they offer API access to customers. If a public API appears, ask your chat to check it again.
- Calendar apps reach iCloud with the open CalDAV calendar standard, but Apple does not document this as an API, so it can change without notice. Changing your Apple Account password revokes all app-specific passwords.

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
