Payment Processors


This guide will walk through setting up Kajabi to take payments using your Adyen account. Using the CheckoutJoy integration, you can take payments using your Adyen account directly from your Kajabi checkout pages.

Supported Payment Options

  • One-time payments
  • Multiple payments
  • Subscriptions

Only once-off offer purchases are supported at the moment. If you want to use Adyen for subscriptions or the multiple payment model, please reach out to us.

Adding your account details

In the CheckoutJoy dashboard

  1. Navigate to Settings > Payment Methods
  2. Select your payment processor and click on Add

Finding your Merchant Account ID

Your Adyen merchant account is the name of your e-commerce merchant account in your Adyen dashboard.

By default Adyen adds "ECOM" to the end of your company name - e.g. the Merchant Account ID of CheckoutJoy is CheckoutJoyECOM.

Finding your Live API Endpoint

Every Adyen account comes with a unique set of API endpoints. The paymentLinks endpoint is required to initiate a payment with Adyen.

The value can be found under the Checkout API section.

The endpoint looks something like this:

https://[random]-[company name]

You can find information on finding this endpoint value here here

Finding your API Key

Every Adyen account comes with a unique API key to enable secure communications with third-party systems.

You can find information on getting your API key here

Server Communication Settings

This refers to the webhook notifications that is sent by Adyen on payment events, e.g. when a payment was completed successfully or a bank transfer has cleared.

You need to enable your account's server communications so that CheckoutJoy is notified of successful and failed payments. This is an important step to ensure that CheckoutJoy automatically grants your customers access to the offer and kicks off the Kajabi member onboarding sequence.

Adyen provides a way to configure these notifications in the Account > Server Communication section.

The URL value is

Webhook Username and Password

The webhook username and password is an added security measure to ensure that the webhook notifications originated from your Adyen account. These values will be checked by CheckoutJoy when processing a webhook notification from Adyen to ensure that the notification is authentic.

Please note - this username and password can be any random value, do not make it your Adyen username and password!
