Adyen Connection Fields

When connecting Swallow to Adyen, you need to provide information for the following fields.

To find your **connection code**, navigate to the Integrations section in Swallow and select the appropriate connection code for your Adyen integration.

Please ensure that you complete this setup correctly, as your Adyen integration will not function without this vital step.

Setting Adyen as a Payment Provider for a customer

In order to facilitate automated payment collection, it is essential for the customer to exist in both the Swallow and Adyen databases. Please note that in Adyen, customers are referred to as Shoppers.

Adding a new customer in Adyen

If the customer does not already exist in Adyen, you can create them in Swallow using either the user interface or the API. When providing customer information, please ensure the following:

1. Set Adyen as the customer's default payment provider;

2. Select the Adyen connected account;

3. Keep the field associated with the Adyen Payment Provider Customer ID empty; and

4. Enable the option to automatically create the customer in Adyen.

Once the customer is added in Swallow, they will be automatically synchronized with Adyen. Adyen will generate a unique Shopper ID, which will be stored in Swallow. Typically, Adyen utilizes the Swallow customer's external_id as the Shopper ID for seamless integration between the two platforms.

Upon successful customer creation, you will receive two webhook messages to keep you informed:

1. customer.checkout_url_generated: This message includes the quote URL that provides access to the default payment method. It allows you to perform a pre-authorization payment and store the payment method securely; and

2. customer.payment_provider_created: This message confirms the successful creation of the customer in Adyen, indicating that the customer's details have been added to the Adyen database.

You may need to enable Developers -> Additional Data -> Payment -> Recurring details for the customer to be automatically created. Please note that the customer will be created in Adyen only if the payment method has been stored through the quote URL and pre-authorization payment.

Using an existing customer from Adyen

If the customer and direct debit mandate already exist in Adyen, you can create the customer record in Swallow using either the user interface or the API. Follow these steps when adding customer information:

1. Set Adyen as the default payment provider for the customer in Swallow;

2. Select the Adyen connected account;

3. Provide the Adyen Shopper Reference as the Swallow Payment provider customer ID.
4. Disable the option to automatically create the customer in Adyen.

By following these steps, you can integrate an existing customer from Adyen into Swallow, ensuring synchronization and consistency between the two platforms.

Redirect url after quote completion

After establishing the connection with Adyen, set a "next button URL" where your end customer will be directed after completing the quote. Please note that if it's not defined, your end customer will be redirected to Adyen's website.

Please note that you can edit or delete the redirect URL, and this will only affect new quote URLs created.

URL defined should always begin with `http://` or `https://`.

Adyen Checkout: storing customer's payment method information

When Swallow automatically creates a customer in Adyen, you will receive a quote link from Swallow to facilitate the storage of your customer's payment method information.

The payload sent by Swallow will have the following structure, with the quote link stored under checkout_url:

{
  "webhook_type": "customer.checkout_url_generated",
  "object_type": "payment_provider_customer_checkout_url",
  "payment_provider_customer_checkout_url": {
    "swallow_customer_id": "88d23508-47fd-46bb-a87e-50c50f3cb371",
    "external_customer_id": "hooli_1234",
    "payment_provider": "adyen",
    "payment_provider_code": "adyen_test",
    "checkout_url": "https://test.adyen.link/PLEEA656869B11DF6B"
  }
}

Note: The quote link automatically expires after 69 days.

By utilizing this provided quote link, your customers can perform a pre-authorization payment. It's important to note that the pre-authorization payment will not collect any funds from the customer. Once the pre-authorization is confirmed, Swallow will send the payment method details and securely store them into Adyen for future transactions.

Regenerate quote link on demand

In cases where your end customer has not had the opportunity to complete the quote process to inform their payment method or wishes to modify the saved payment information, you can generate a new quote link using the designated endpoint.

POST /sw/customers/:customer_reference/checkout_url

Upon successful generation, the new quote link will be available in the endpoint response, and it will not be delivered through a webhook message. It is important to note that the new link will inherit the same expiration setting as the original one.

It is crucial to be aware that if a customer is not associated with any payment provider, the response will contain an error message.

Creating payments from Swallow Quotes

When a customer has Adyen defined as their payment provider, Swallow seamlessly automates the process of triggering payments in Adyen whenever a new quote is generated.

This integration ensures that payments are initiated in Adyen without any manual intervention. Swallow's automatic payment creation saves time and effort, providing a streamlined experience for both you and your customers.

Creating refunds from Swallow Credit Notes

In cases where a customer has Adyen defined as their payment provider, Swallow simplifies the refund process by automatically triggering refunds in Adyen whenever a new refund is initiated through credit notes.

This integration eliminates the need for manual refund processing and ensures that refunds are efficiently handled in Adyen. Swallow's automated refund functionality helps you maintain accurate and timely refund transactions, enhancing customer satisfaction and operational efficiency.

Payment disputes

In the event of a lost chargeback (dispute) within Adyen, Swallow initiates an automatic response by marking the relevant quote as disputed lost. This action involves populating the dispute_lost_at field with the timestamp when the dispute was lost. Following this update:

• The quote becomes non-voidable;

• Generating a credit note is possible; however, refunding the payment back to the original payment method is not permitted; and

• The quote cannot be resent for collection.
