The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.
Add a Google Calendar connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.
Start from a Google Calendar event, or from a WordPress event, a form, a webhook, a schedule or any of the 918+ integrations, then capture a sample so later steps can map real fields.
Chain Google Calendar actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.
Each example pairs Google Calendar with an app it is often used with. Build any of them on the canvas, or start from the workflow library.
