The integration of Tikkie Fast Checkout on your website enables your clients to experience a more smooth and fast checkout.

The Fast Checkout button can de added to the PDP (Product Detail Page) and/or placed in the shopping cart before the checkout page.

How do I get started with Tikkie Fast Checkout?

In this store you are able to download the plug-in. In order to receive your test keys, please fill in the following form (in Dutch). After having applied for the keys you will also receive instructions on how to configure the plug-in and finally go into production with the live keys.

What are the costs?

For Tikkie we have the following cost structure per transaction. Every month will be individually calculated:

Price per Transaction

<101 Transactions
€ 0,25

101 – 500 Transactions
€ 0,20

>500 Transactions
€ 0,15

Where can I create my API Key/Merchant Token?

In order to obtain the test Key/Merchant Token you will need to fill in the application form via the following link (in Dutch). Depending on whether you are already have a Tikkie account you will also receive the live Key/Merchant Token.

Why does the plug-in not work when going to production?

When going to production you have to make sure that you check the box that says ‘enable production mode’. A warning will appear in red to inform you that test-mode is disabled and that real payments will be processed from now on.

How can I customize the appearance of the Fast Checkout button?

Custom styling can either be done with custom CSS or by adding a class in the tk_show_button function.

Why is my Fast Checkout button not shown?

There could be a few reasons why the Fast Checkout button is not shown:
1. The payment method has not been activated
2. The show on cart/production detail page button is not checked
3. The API-Key and Merchant Token are not entered for the mode (test/production) you are in
4. The product is external
