About the Payment Settings Service Plugin
As a payment settings provider, you can integrate your service with Wix's payment process to allow merchants to request and use your services on their Wix sites. By integrating your service with Wix, the payment settings that are checked will then apply during the payment process.
The integration is done via an app in the Wix App Market and by implementing the Payment Settings service plugin. After the app is installed on a site, Wix triggers a call to your service when an order is placed from the checkout page of the site.
Using the service plugin, you can design your app to apply specific settings and send additional information to the payment provider. Currently, the only payment setting available to customize is whether to apply 3DS to an order. If 3DS is required, the customer will have to pass an additional layer of security before completing their payment. For example:
Before you begin
It's important to note the following points before starting to code:
- To collect payments, a Wix site must connect a payment provider.
- We recommend contacting payment providers directly to confirm which payment settings they have implemented as part of their Wix integration.
Terminology
- 3 Domain Security (3DS): An additional layer of security for online credit and debit card transactions.
