Prepare credentials​

Apple​

For apple you want to go to this page and after following the guide, you will have Apple ID and app-specific password.

Google​

For google you want to go to Google Cloud Platform/Credentials page, then create a credential that suite your use case. You want clientId ,client secret and after this. Also you need to enable Google CALDAV/CARDDAV for your project.

Also you need to setup oauth screen, add needed oauth2 scopes (https://www.googleapis.com/auth/calendar for CalDAV), use proper oauth2 grant flow and you might need to get your application verified by google in order to be able to use CALDAV/CARDDAV api. Refer to this page for more details.

After the oauth2 offline grant you should be able to obtain oauth2 refresh token.

Fastmail​

Generate an app specific password just like apple, follow this guide for more information.

Other cloud providers not listed are not currently tested, in theory any cloud with basic auth and oauth2 should work, stay tuned for updates.

Caveats​

Some cloud providers' APIs are not very standard, they might includes several quirks.

Google​
  1. CALDAV will always use UID inside ics file as filename, for example if you created a new event with name 1.ics but have abc as its UID inside, you can only access it using abc.ics.
  2. CARDDAV will always generate a new UID for your .vcf files. For example a file created with name 1.vcf with UID abc, it will have a UID like 1bcde2e inside the actual created data.
  3. Both CALDAV and CARDDAV will add custom data entries inside your ics and vcf files like new PRODID, new TIMETAMP and some custom X- fields.
  4. For CARDDAV, you cannot create a vcf file with the same name again even if it's already deleted.

  1. Object deletion will result in original object be renamed rather than actual deletion. This can cause problems at times.
