Your software platform
Connect an ERP, ISV product, vertical SaaS application, or enterprise workflow to the middleware.
INTEGRATIONS
Connect your software to the financial workflows it needs.
Split Rail sits between your application and integrated financial providers. APIs carry commands and workflow data; business rules determine what happens next; webhooks help keep systems informed as events occur.
What the middleware enables
One integration layer. Two core middleware products.
Payment orchestration and AI-driven accounts receivable share an integration-first foundation, while accounts payable remains an expandable capability of the platform.
Split Rail middleware
Apply orchestration logic, AI receivables workflows, configurable rules, and financial instructions.
Card and ACH providers
Direct integrated payment providers to execute supported transactions and disbursements.
APIs for instructions
Send invoice, payout, payment, and workflow commands from the platform.
Webhooks for events
Receive updates to help reconcile state and trigger downstream business actions.
Room to expand
Extend existing receivables-oriented workflows into deeper accounts payable use cases as needed.
Technical note: This page illustrates the integration approach; it is not a public API specification. Endpoint definitions, authentication, supported processors, and developer documentation should be added after technical validation.
