Order Form Button for Recur Billing

This example demonstrates how to create a payment button that redirects customers to a Plug’n Pay hosted payment page and enrolls them into a recurring billing plan.

When the payment is completed, the transaction will automatically be associated with the recurring billing plan specified by the pr_plan_id field.

Requirements

Before implementing recurring billing integrations:

  1. Your account must be enabled for the Plug’n Pay Recurring Billing Service.
  2. The pr_plan_id value must match an existing Payment Plan ID configured within your Plug’n Pay account.
  3. The recurring billing plan must already be created before submitting transactions.

Example Code

<form method="POST" action="https://pay1.plugnpay.com/pay/">
  <input type="hidden" name="pt_gateway_account" value="USERNAME">
  <input type="hidden" name="pt_transaction_amount" value="5.00">
  <input type="hidden" name="pr_plan_id" value="1">
  <input type="submit" value="Subscribe Now">
</form>

How It Works

Field Description
method="POST" Sends the payment data securely using an HTTP POST request.
action="https://pay1.plugnpay.com/pay/" The Plug’n Pay hosted payment page URL.
pt_gateway_account Your Plug’n Pay gateway account username.
pt_transaction_amount The payment amount submitted with the transaction.
pr_plan_id The recurring billing plan ID associated with the transaction.
type="submit" Creates the payment button shown to the customer.

Required Changes

Before using this example in production:

  1. Replace USERNAME with your Plug’n Pay gateway account username.
  2. Replace the transaction amount with your desired recurring payment amount.
  3. Replace pr_plan_id with a valid Payment Plan ID from your account.

Example:

<input type="hidden" name="pr_plan_id" value="monthly_plan">

Customized Example

<form method="POST" action="https://pay1.plugnpay.com/pay/">
  <input type="hidden" name="pt_gateway_account" value="youraccount">
  <input type="hidden" name="pt_transaction_amount" value="29.99">
  <input type="hidden" name="pr_plan_id" value="monthly_plan">
  <input type="submit" value="Start Subscription">
</form>

Customer Flow

  1. Customer clicks the subscription button.
  2. Customer is redirected to the Plug’n Pay hosted payment page.
  3. The recurring billing plan is automatically linked to the transaction.
  4. Customer securely enters payment information.
  5. The payment is processed and the recurring billing profile is created.

Notes

  • The recurring billing schedule and processing rules are controlled by the Payment Plan configuration within your Plug’n Pay account.
  • The pr_plan_id field references an existing plan and does not create plans dynamically.
  • Hosted payment pages help reduce PCI exposure by securely collecting payment information on Plug’n Pay servers.
  • Additional billing, shipping, and customer information fields may also be submitted.
