Adyen is one of the most popular enterprise-grade online payment processing platforms for e-commerce. It helps merchants to accept 💳 credit and debit card payments (Visa, Mastercard, Maestro, American Express, Discover and Diners, China UnionPay, JCB, Cartes Bancaires, Interac, etc.) as well as hundreds of local and alternative payment methods.

It is possible to enable payments via third-party payment services as iDEAL, Sofort, SEPA Direct Debit, Afterpay and etc. For more info about this payment provider and the payment methods this integration unlocks please visit https://docs.adyen.com/payment-methods.

To enable Adyen as a payment gateway on your store, you must have an Adyen live account. If you do not have one, please read their Get started with Adyen.

Also note that the minimal transaction you can have on Adyen is (equivalent to) €0.02.

ATTENTION: Most of the payment methods require presence of shipping (details) fields. Therefore, if you are customizing the checkout's address form, keep in mind that some methods may stop working correctly because of that. Please monitor this case. If a payment method stopped working after introducing a custom shipping form for your checkout, deactivate such a method in your Adyen account or roll back to the initial version of the address form.

Visit admin > Payment methods to get started. Keep this page open in a tab.

9. Proceed to Developers > API URLs > Prefix and get your Prefix:

10. Copy your prefix and paste it to Checkify into the corresponding field.

11. Once all the four fields are completed, click Connect + button to enable Adyen.

You need to configure terms & conditions in your Adyen account settings for the specific account/entity used with Checkify before the full scale launch.

Please guide them with these steps:

Once this is saved, the checkout redirection, whenever is required, should work instantly.

When adding Adyen as a payment method on Checkify, you will also able to configure additional options:

i. Target countries

You can select specific countries or regions for which this payment method will be displayed.

ii. Hide / reveal card payments option on the checkout page.

You can visit admin.checkify > Payment methods section > Settings tab and disable displaying of the card payments form on the checkout page. If hidden, your buyers will still get the option of paying using alternative payment methods.

iii. Risk management
You can adjust your risk tolerance in Adyen > Settings > Risk (Protect).

Please note that completely disabling Adyen's risk engine may result in a higher chargeback rate. Conversely, if your business is experiencing a high number of blocked legitimate transactions, you should fine-tune your settings to be less aggressive.

Risk profiles are specific to each merchant account. The account connected to Checkify Pro can have its own unique set of policies, independent of other merchant accounts within your organization.

iv. Branding

You can further work on design and brand consistency of your payment step on Adyen-hosted pages by creating a themein Adyen > Pay by Link > Themes.

Give your theme an internal name, add the display name. Apply the design settings. And then press "Create" button.

Once saved and applied, your non-Shopify and non-Checkify pages will be consistent with the whole branding, cementing trust and improving conversions.

Our integration allows secure transfer of the customer's payment data directly to Adyen while using a unique design of the payment info section. The payment data fields are loaded directly from Adyen’s servers. It means that Checkify does not handle or has any access to your customers' card data.
​

You may visit our Demo store, proceed to the checkout and have a look at the example of the setup in the Payment block.

Adyen leverages its own 3DS Engine by default, which means that all payments are fraud-protected and compliant with the European Directives. The 3D Secure screen is shown only when requested by the bank of a customer.

Adyen’s payment methods operate on the Checkify-hosted checkout page (non-redirect), or via a redirect flow. In case of the latter, the buyer leaves the checkout page, completes the transaction on the provider's site before receiving the confirmation.

The Check order status button verifies if the order confirmation page is available.

If available: The buyer is automatically redirected to the order confirmation (thank you) page by Checkify.

If pending: The system returns an 'Awaiting payment confirmation' message.

The texts related to Adyen on Checkify can be edited, customized and translated (manually) in the Localization section of the admin.

All payment methods initially perform a pre-authorization of the payment sum and then, upon a successful charge on the bank's side, Adyen changes the status of the payment to either Failed or Success. In such cases payment processing may take from couple of minutes to seven days. It is being managed by Adyen and Checkify has no influence on it, and has no ability to speed it up. You can track the status of such orders in your Shopify admin. It is not recommended to ship an order to your customer when "Payment pending" status is seen. When the payment status changes to "Paid", feel free to dispatch the order:

Once the processing by Adyen is over, the status on Shopify changes automatically to either Paid or Void (if Adyen returned a Failed status):

Adyen currently supports about 144 currencies. You can charge customers in one of them. The full list is available in their technical documentation on their website.

If the checkout currency is not one of them, the Adyen integration will not work. This is not a limitation for your buyers, whose cards may still be in any other currency, even those outside the list of supported ones.

The Adyen-hosted payment page can be presented in close to 30 different languages. It is fewer than the total on Checkify. If the checkout page is in a language not supported by the payment provider, then its post-redirect payment elements will appear in English. Once the buyer completes the purchase, the order confirmation (thank you) page by Checkify will be displayed in their native language again.

For "Other methods" to work, you must add your store's terms & conditions URL in the Pay by Link settings of your Adyen admin. Adyen must contain links to terms (legal docs, policies) on their hosted pages. Here, in item 2.3 of this article, we explain more.
​

If you open browser's console at the checkout page and see responses (errors in red) like this Access to fetch at ‘…’ has been blocked by CORS policy: Response to preflight request doesn't pass access control check: … Failed to load resource: net::ERR_FAILED, please do the following:

Add allowed origin (your store's domain) manually to your Adyen account.

Visit Developers > API credentials, the section where you got your API credential. Scroll down this page to reach “Add allowed origins” (domains) field (bellow Client Key).

See the screenshot below:

In case the statuses of completed orders remain pending, please visit Adyen admin and check Webhook event logs. If you encounter some failed statuses, press "Retry" as shown in the screenshot.

This operation is generally automated and there is very low probability that such manual actions may be required. But still, it is good to know and to check.
​

It is a pretty common situation when an Adyen account is used in various places / businesses. We recommend to create a separate merchant account. Add "checkify" to its name in Adyen in order to see transactions only related to our checkout. Otherwise, there is a risk of accumulating a mixture of transactions. When exploring webhooks you will also encounter a mix of those related and unrelated to Checkify's operation.
