Before you follow the steps detailed on this page here, it's important that your Bookwhen page is Worldpay compliant.
Firstly, make sure you've entered your business details here. Select Edit under the Account details section.
Then add a refund policy here (select Edit on the left-hand box). A refund policy can be really simple, but this is just on the principle of transparency.
Both these elements, along with accepted card type logos, will then be shown on the footer of your public booking page.
Integrating Worldpay Online with Bookwhen
You can then make a test booking using this dummy Visa card number: [4444 3333 2222 1111] (with any other details, for example, CSV 123).
Worldpay will then contact you (normally within 30 minutes) to ask a few questions and to start the account activation process.
Once your account is activated (normally within 24 hours, however, this can take up to 10 working days) you can then enter your LIVE API keys and start accepting live payments.
When selecting the integration type with Worldpay, please select 'Direct API Integration'.
If you want to be able to withdraw funds immediately from your Worldpay account, you must provide bank statements that are dated within the last 3 months. Worldpay can accept screenshots of bank statements for proof.
