For ISVs & Software Providers

Embed payments. Monetize the platform.

The CoreGateway ISV Program lets software providers embed payments into their SaaS or vertical software through a clean REST API. Turn payments from a cost center into a revenue stream, white-label the experience, and onboard sub-merchants programmatically.

Key benefits

Built for product teams that ship.

A gateway integration shouldn't be your roadmap's blocker. CoreGateway gets out of the way.

Developer-first API

REST + JSON. User-friendly developer guide for direct integration. Sandbox provided upon request. Standard auth schemes. No XML. No SOAP.

Monetize transactions

Earn a share of every transaction processed through your platform. Payments become a meaningful revenue line, not just a cost of doing business.

Fully white-label option

Brand the dashboard, the receipts, the API responses. Your users see your product, not CoreCommerce. Available with the full white-label ISV agreement.

Sub-merchant onboarding API

Programmatically onboard your customers as merchants. Status updates, KYC, processor placement - all driven from your application.

Every gateway feature available

Vault, recurring, surcharging, L2/L3, ACH. The same API surfaces every CoreGateway feature - your product can ship the parts your users need.

Dedicated technical support

You get a named integration engineer for the initial build, then ongoing access to developer support. Not a generic ticket queue.

Questions

ISV Partner FAQ.

What does the revenue model look like?
A share of the processing fee on every transaction your platform initiates. Specific economics depend on volume, vertical, and the merchant-onboarding model. We'll walk through the math on the partner call.
Is the integration completely white-label?
Yes, with the white-label ISV agreement. The dashboard, the API responses, the email receipts, and the support emails are presented in your brand.
Do you have a sandbox?
Yes. Sandbox keys with simulated card responses, simulated decline scenarios, and full API parity with production. See the developer guide →
How do I onboard merchants?
Via the sub-merchant API - your platform creates merchant accounts programmatically. Status updates flow through the API as merchants move through underwriting, approval, and activation. Standard merchants approve in 1-2 business days.
What technical support do I get?
A named integration engineer for the build, plus ongoing developer support. We work alongside your team during the integration - not just a ticket queue.
