Next step#

You can add more features to your integration as needed

Create a Webhook#

Listen to events on your WooshPay account so your integration can automatically trigger reactions. Create a webhook that mainly focuses on enabled_events and url.

Create a Refund#

Create a refund to repay funds to your customer. You can also perform partial refunds, but not every payment method supports them. A partial refund is when you refund only part of the original transaction amount.
