Welcome to the Exact Payments Developer Portal

Exact Payments builds and manages a technology platform which enables SaaS companies to quickly and seamlessly embed payments functionality into their software to monetize payments. We offer this as a service, referring to it as ‘Payfac-as-a-Service’

First, the Software Partner must complete a very simple integration with one of 2 methods

  • Our Hosted Merchant Application
  • Our Onboarding API (to pass data collected in their own application process)

Second, the software partner or merchant has the option to integrate for payments and/or reporting using our APIs. However, partners can pass on these options and instead have their clients (merchants) integrate directly to our platform for:

  • Payments using our ExactJS UI components
  • Reporting using our online merchant portal

Exact's Embedded Payments Platform encompasses all the services needed to build a custom comprehensive payments experience into any software application. This includes a real-time underwriting and onboarding service that automates approval and account set-up for new customer (merchant) accounts. From there, the platform delivers complete payment acceptance capabilities including—credit, debit, ACH, Paypal, Apple Pay, Google Pay, and Click to Pay, as well as settlement, funding, fees, chargeback, fraud management, and comprehensive reporting tools. With Exact's rich set of APIs, you have everything you need to build ideal payment experiences for any customer journey.

Exact's Embedded Payments Platform offers a REST API. This API accepts and responds with JSON request and response bodies. All of our endpoints use standard HTTP verbs and response codes, and we use header-based authentication.

Implementing Embedded Payments

Using our Payfac-as-a-Service modular APIs, you can integrate payments in several ways from using drop-in components to building your own UI for full control over your payments experience.
