Payfast API的ITN回调：如何在仪表盘生成的HTML代码中集成Notify URL？

Hey there! Adding the Notify URL to your existing Payfast setup is straightforward—you just need to include a hidden input field in the form that your JavaScript function is submitting. Here's how to do it:

Step 1: Locate the Payfast Form in Your HTML #

First, find the <form> element linked to the click_8eb310a4f3ae8dcc6556286f70cbd30f function. This form should already have fields like amount, custom, and other required Payfast inputs.

Step 2: Insert the Notify URL Hidden Input #

Inside that <form> tag, add a new hidden input named notify_url, with its value set to your actual notification endpoint URL. Here's the code for that input:

<input type="hidden" name="notify_url" value="https://your-domain.com/your-payfast-notification-handler">

Replace the value with your own public URL where Payfast will send payment status updates (like successful or failed transactions).

Example of the Updated Form #

If your original form looks like this:

<form id="payfast-checkout" action="https://www.payfast.co.za/eng/process" method="post">
  <input type="hidden" name="merchant_id" value="your-merchant-id">
  <input type="hidden" name="amount" value="50.00">
  <!-- Other existing Payfast fields -->
  <button type="button" onclick="click_8eb310a4f3ae8dcc6556286f70cbd30f(this.form)">Complete Payment</button>
</form>

Your updated form with the Notify URL will look like this:

<form id="payfast-checkout" action="https://www.payfast.co.za/eng/process" method="post">
  <input type="hidden" name="merchant_id" value="your-merchant-id">
  <input type="hidden" name="amount" value="50.00">
  <!-- Added Notify URL field -->
  <input type="hidden" name="notify_url" value="https://your-domain.com/your-payfast-notification-handler">
  <!-- Other existing Payfast fields -->
  <button type="button" onclick="click_8eb310a4f3ae8dcc6556286f70cbd30f(this.form)">Complete Payment</button>
</form>

Quick Notes #

• Ensure your Notify URL is publicly accessible (Payfast needs to reach it to send notifications).
• The field name notify_url is case-sensitive—don’t misspell it!
• If you generate the form dynamically via JavaScript, you can also create this input programmatically inside the click_8eb310a4f3ae8dcc6556286f70cbd30f function before submitting the form.
