Glossary

The Woosa server that sits between your shop and Adyen. You send your requests here.

The payment processor that actually moves the money. You never call it directly.

The unique id Adyen gives a payment. Your handle for capturing, refunding, or cancelling it.

The id of a store you created. It goes in the URL of most payment calls.

The legal entity (company or individual) that receives the money.

The secret key Woosa gives your shop during registration. Used to sign every request.

A tamper-proof seal computed per request, proving it came from you and was not altered.

The standard one-way scrambling function used to build the signature.

A simple API login where the caller sends a username and password. Woosa uses your key and secret this way when calling your shop back.

Authorise the payment method (e.g. credit card) of the customer, but not yet charge the actual card.

Charge the payment method of the customer that was authorised.

The identity and compliance checks a merchant must pass before taking real payments.

Saving a shopper's card or method so they can pay again later with one click, or for subscriptions.

The smallest unit of a currency. Cents for euros. 28.00 EUR is 2800.

Free-form data (like your own order id) that you attach to a payment and Woosa gives back to you later, so you can match payments to orders.
