Collect data

When processing payments on the plataforma de pagamentos da Adyen, we send you payment details containing data you can use to identify customers. You can import these identifiers into your own data warehouse to create granular customer profiles and gain insights into your customers.

Requirements

To collect customer identifiers, you need to:

1. Consider data privacy.
2. Understand the identifiers you could use.
3. Set up webhooks to receive standard webhooks. With this, you receive a webhook event for every payment, regardless of the sales channel. The webhook event contains the payment details, including customer identifiers.

Overview of identifiers

To gain insights and create customer profiles, these are the identifiers you could collect:

• Card alias: a value that uniquely represents the shopper's card number (PAN), for example A373176724022941. With this, you can recognize the card that a shopper is using and identify if they are returning customers. You cannot use the card alias for making payments. For NFC wallet transactions, there's no card alias because the PAN is not available.

• Payment Account Reference (PAR): the PAR is an identifier behind the card or NFC wallet. It represents the payment account that the card and/or NFC wallet is linked to. It solves the issue with the PAN not being available for NFC wallet transactions. You can use the PAR to identify the shopper.

• Shopper reference: a unique reference defined by you and stored on the plataforma de pagamentos da Adyen. Each shopper reference must have a minimum length of three characters, and should not include personally identifiable information (PII), such as name or email address. With the shopper reference, you can recognize the shopper who makes the purchase. If you collect the shopper's email address, you can link multiple card aliases, shopper references, and recurring detail references (tokens) to the same shopper through their email address. The shopper reference and the recurring detail reference are necessary for making recurring contract payments.

• Shopper email: the shopper's email address that you collected in some way, and stored on the plataforma de pagamentos da Adyen when creating a recurring contract.

For analysis purposes, you can also collect:

• Funding source: funding source of the card, for example debit, credit, or prepaid.

• Issuer country: the two-letter country code and the numeric country code of the country where the card was issued. This is a good indicator of the shopper's country/region of residence.

Using data from webhooks

To combine data from multiple sales channels, we recommend using standard webhooks for all channels. Standard webhooks are generated on our platform. They have the same format and are delivered in the same way across channels. This makes it easier to set up your integration for collecting data.

To receive identifiers as additionalData included in standard webhooks:

1. Set up a standard webhook, if you haven't done so already.

2. In your Customer Area, open the Standard webhook you set up and select the additional settings you want to receive.

   Some of the settings you may want to enable, are:

   Identifier	Additional setting to select
   Card alias	Include Alias Info
   Funding source	Include Funding Source
   Issuer country	Include Issuer Country
   PAR	Add Payment Account Reference Must be enabled under Developers > Additional data too.
   Recurring detail reference	Can't be enabled in the webhook settings. Must be enabled under Developers > Additional data.
   Shopper email, shopper reference	Include Shopper Details
   Token variant	Include tokenTxVariant Must be enabled under Developers > Additional data too.

3. To receive the PAR, the token variant, or the recurring detail reference in standard webhooks, go to Developers > Additional data and enable these identifiers:

   Identifier	Additional data to select
   PAR	Under Acquirer, select Payment account reference
   Token variant	Under Card, select Token information for digital wallets
   Recurring detail reference	Under Payment, select Recurring details

   When you enable identifiers under Developers > Additional data you also receive these identifiers in your API responses.

Example standard webhook

The following example shows the standard webhook for a point-of-sale payment. The identifiers are in the additionalData object.

Using data from Terminal API responses

If you have a point-of-sale integration with our Terminal API, you could use the Terminal API payment responses to collect customer data. The same identifiers that are returned in standard webhooks, are also returned in Terminal API payment responses. However, the format is different.

Refer to Receiving identifiers in Terminal API responses for more information and an example.
