Custom Integrations

When do you need a custom integration?#

Split Pay is designed to work with standard WooCommerce product types (simple, variable, grouped) and the supported integrations. However, some WooCommerce extensions create non-standard product types or alter the checkout process in ways that prevent Split Pay from detecting products correctly.

Common scenarios where this may occur:

• Custom product types registered by third-party plugins (e.g., "booking," "appointment," "rental," etc.)
• Products created dynamically at checkout without standard WooCommerce line items
• Checkout flows that bypass the standard WooCommerce order creation process
• Plugins that modify the Stripe charge metadata in ways that conflict with Split Pay

Option 1: use global transfer settings#

The simplest workaround is to rely on global transfer settings. When Split Pay cannot detect product-level settings for a line item, it falls back to the global transfer configuration. If your global settings are appropriate for these products, no further action is needed.

Option 2: request a custom integration#

If global settings are not sufficient and you need product-level control for non-standard product types, you can request a custom integration from the Split Pay development team.

To submit a request:

Our team reviews all integration requests and prioritizes them based on demand. If the plugin uses standard WooCommerce order line items internally, integration is typically straightforward.

Option 3: use developer filters#

For developers or stores with development resources, Split Pay provides documented WordPress extension points for supported routing and integration work. WooCommerce runtime filters can alter a transfer plan without rewriting saved product settings; a different checkout platform needs a registered Split Pay integration adapter.

With developer filters, you can:

• Use spp_product_recipient_transfer to alter one calculated WooCommerce product-recipient row.
• Use spp_order_items to append or modify index-aligned WooCommerce TransferableItem routing.
• Use the documented product-save filters when the customization should change saved product settings rather than one order’s runtime plan.
• Use spp_register_integrations to register a complete adapter for another checkout platform.
