To integrate iDEAL payments, you need three code integration points:

1. Initialize the payment:
   Call the Lemonway DirectKit API to start an iDEAL transaction and obtain the payment URL and transaction reference.
2. Redirect the user:
   Send the customer’s browser to the iDEAL redirect URL, then have them return to your specified return URL once they complete or cancel the payment.
3. Finalize the transaction:
   After the redirect, call the Lemonway DirectKit API to finalize the iDEAL payment and credit the user’s payment account.

Important: Whenever you see accountId in a path or body parameter, enter your wallet’s ID.
