Use webhooks with split payments

When using split payments, each payment authorization for a gateway integrations is managed individually using the webhook appropriate for that gateway, such as the Generic Payment webhook or the Credit Card Payment webhook.

Payment authorizations for built-in gateways, such as CyberSource, are managed internally. A separate call is made for each payment group.

Webhooks that include payment data for entire orders, however, must handle multiple payment groups. The request bodies of the following webhooks can include multiple payment groups, one for each payment method instance used in the order:

• Order Submit
• Order Submit Without Payment Details
• Cart Idle
• External Price Validation
• Return Request Update
• Return Request Update for Without Payment Details
