Initiates a new withdrawal returning the url where the end-user can complete the process.

You can find more information about how to display the Trustly URL here.

A typical withdrawal flow is:

  1. The merchant makes an API-call to Withdraw method and load the URL in an iframe for the end-user.
  2. The end-user selects the amount to withdraw and provides his/her bank account details.
  3. Trustly sends a debit notification to the merchant's system to deduct the specified withdrawal amount from the end-user's balance in the merchant's system. If the debit notification failed, the withdrawal is aborted and the end-user informed.
  4. If manual approval is required, Trustly does nothing with the withdrawal request until it has been approved or denied with ApproveWithdrawal / DenyWithdrawal .
  5. When approved, Trustly process the withdrawal request. If the withdrawal is denied, Trustly will send a credit notification and the withdrawal will not be processed.
  6. Please note that in case of a successful Withdrawal, no additional notification will be sent to the merchant's NotificationURL after the Withdrawal has been approved. But if the Withdrawal fails, a credit notification will be sent (see more details below under "Failed Withdrawals").

Failed withdrawals

In case an error occurs when processing the withdrawal, a credit notification will be sent to the provided NotificationURL so that the merchant can flag the withdrawal as failed in their system. And in case the end-user holds a balance on the merchant's system, the amount specified in the credit notification should be credited back to the end user's balance. Note that the credit notification will be sent AFTER the withdrawal has been successfully approved (either automatically or by sending ApproveWithdrawal .

There are 2 main reasons why a Withdrawal can fail after being approved:

  1. There are not enough funds on the merchant's Trustly account. In this case the credit notification will be sent immediately after the withdrawal has been approved.
  2. The funds are sent to the end user's bank account, but then later Trustly is notified by the bank that the transfer failed, for example if the recipient's bank account has been closed. This is usually very uncommon, but if it happens the credit notification can be sent several days after the Withdrawal has been approved.

In case something is wrong in the Withdrawal API call itself, you will receive a synchronous API error code. A list of the most common error codes can be found here.
