The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.
Add a Calendly connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.
Start from a Calendly 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 Calendly actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.
Each example pairs Calendly with an app it is often used with. Build any of them on the canvas, or start from the workflow library.

Crafting bridges between my favorite apps, FlowMattic has truly impressed me with its ability to seamlessly automate workflows. This has noticeably accelerated the efficiency of my business processes, making everything run more smoothly and productively.
It's very straightforward, has a lot integrations and they work well. It is one thing to 'integrate' new external software, but integrating it well, with lots of options is where FlowMattic shines.
