Three steps to a running Cal ID workflow

The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.

  1. Connect

    Authorise Cal ID once

    Add a Cal ID connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.

  2. Trigger

    Pick what starts it

    Start from a Cal ID 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.

  3. Act

    Add Cal ID steps and logic

    Chain Cal ID actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.

The main advantage of the plugin that it can turn your WordPress installation into a powerhouse, just imagine that you can replace all other integration with only this one.

No additional usage fees over and above the annual fee ... AND Technical Support is great... they get back to you quite quickly and go above and beyond what is expected...
