Connect PayPal to KlickTipp via IPN interface

In this article, you’ll learn how to connect PayPal to KlickTipp to manage your payment transactions more efficiently.

Step-by-Step Instructions

In this step-by-step guide, you’ll learn how to correctly connect PayPal to KlickTipp.
First, you set up your PayPal product in KlickTipp, then activate payment confirmation in PayPal, and finally create the product code.

Optionally, you’ll learn how to transfer additional parameters to KlickTipp via self-hosted PayPal buttons to automatically tag buyer status and data.

Settings in KlickTipp

  • Select → List Building → New List Building  from the menu and click on the PayPal icon.
  • Create a new PayPal product and give your product a name.
  • Select → Catch-all Product  (applies to all your PayPal products) or → Specific Product.
  • Click → Create PayPal Product.
  • KlickTipp automatically generates the → PayPal product code  and the → payment confirmation URL.
  • In the → Opt-in process section,  select an opt-in process for your PayPal product.
  • Optionally, you can enable the checkbox → Subscription requires full payment.
  • In addition, select the subscription term, the amount from which the lead value should be calculated, and the email you want to use for sending invoices.
  • Now you can tag payment statuses. KlickTipp automatically recognizes the buyer status and assigns the corresponding tag. Enter a tag for the events → Successful payment, → Refund, → Chargeback,  and → Subscription cancellation.

Settings in PayPal

Enable Instant Payment Notification (IPN)

  • Now switch to your PayPal account to activate IPN notifications.
  • To do this, click on the blue button with the initials of the PayPal account holder in the top right-hand corner.
  • Then select → Account Settings.
  • At the bottom left of the side menu, you will find → Website Payment Solutions,  which you click on once.
  • You will see the entry → Instant Payment Notification.  Go to → Edit on the right.
  • In the next window, select → Edit settings.
  • In the field provided, enter the → Payment confirmation URL  provided by KlickTipp in the edit dialog of your PayPal product.
  • Finally, click → Save.

Create PayPal Product with Product Code

  • Go to the home page of your PayPal account. There, under → Quick Access,  you will find the button → Payment Links and Buttons.
  • In the next window, click on the → Show more options  button at the bottom.
  • Activate the → Product code  option using the switch and enter the product code provided by KlickTipp in the editing dialog of your PayPal product.

Transfer of Additional Parameters

KlickTipp allows you to receive additional parameters with each purchase and transfer them to individual data fields.

This option is only available for self-hosted PayPal buttons, as PayPal does not support additional parameters for its own buttons. Learn how to create a button and what code you need for it.

We provide the sample code here:


  
  <input type="hidden" name="business" value="<>">
  <input type="hidden" name="item_number" value="<>">
  <input type="hidden" name="item_name" value="<>">
  <input type="hidden" name="amount" value="<>">
  <input type="hidden" name="currency_code" value="<>">
  <input type="hidden" name="custom" value="<>">
  <input type="hidden" name="notify_url" value="<>">
  <button type="submit">Jetzt zahlen</button>
Kopieren

The following hidden fields must be included in your code at a minimum:

  • item_number
  • notify_url

In addition, you can transfer a reference parameter to KlickTipp.

  • The name of the parameter in the code is → custom.
  • Enter the value in your PayPal list building in KlickTipp in the field under → Reference parameter (custom).

Now you know how to connect PayPal to KlickTipp. With this integration, payments are processed automatically and buyer statuses are reliably tagged.

Follow the instructions to ensure that every transaction is correctly recorded and tracked. Optimize your payment system by effectively linking PayPal with KlickTipp.
