Calendar currently has no built in importing options available. However, through the Verbb Feed Me plugin, you can import and/or update existing Calendar events using the Calendar helper plugin. Importing tools are very complex to get right, and rather than reinventing the wheel we've decided to recommend the Feed Me plugin.
Currently, there are 5 different feed types available to choose from:
You can select which calendar to check against, and decide from any of the following behaviors:
- Create new events: Adds new events if they do not already exist.
- Update existing events: Updates events that match the Unique Identifier (next step).
- Disable missing events: Disables any events that are missing from the feed.
- Delete missing events: Deletes any events that are missing from the feed. Be careful.
