The Gravity Flow PayPal Extension is a specialized add-on designed to integrate payment processing directly into your automated workflows. Unlike a standard form that requires payment at the moment of submission, this extension allows you to trigger a payment request at any specific stage of a business process.

The primary “superpower” of this extension is flexibility. Here is how it typically functions in a real-world workflow:
Payment After Approval: Instead of asking for money upfront, you can set up a workflow where a manager must approve an application first. Once approved, the system automatically emails the user a link to pay via PayPal to finalize the process.
Single Payment Step: You can insert exactly one PayPal step per workflow. This is ideal for registration fees, permit costs, or service payments that occur mid-process.
User-Friendly Redirects: When the workflow reaches the PayPal step, the “assignee” (the person paying) is directed to PayPal to complete the transaction and then sent back to your site to trigger the next step in the flow.
To use this extension, your WordPress site needs a specific “stack” of plugins:
Gravity Forms: The core form builder.
Gravity Forms PayPal Add-On: (Standard or Checkout) To handle the actual gateway connection.
Gravity Flow: The core workflow engine.
Gravity Flow PayPal Extension: This specific bridge plugin.
