A modern payment gateway. Built for the way merchants pay now.
Authorize.net has been around since the 1990s and it shows. CoreGateway does the same job - card-not-present, recurring billing, virtual terminal, hosted page - with a cleaner REST API, multi-processor support, and built-in surcharging, without burying standard features behind per-module fees.

What you get on CoreGateway that Authorize.net does not bundle.
These are the six biggest reasons developers and merchants migrate. Each one is standard on CoreGateway. On Authorize.net, many of these are separate modules or add-on fees.
Customer vault included
Tokenize and store cards for returning customers and recurring charges, built in - not a separate add-on module.
Published, transparent pricing
$20/month plus transparent processing you can price out up front, with no rate negotiated through a reseller layer.
Recurring billing + card updater
Subscriptions and payment plans are standard, and the automatic card updater prevents failed charges when a customer's card expires.
Modern REST API
Clean REST and JSON with sandbox keys and clear docs, instead of a legacy XML integration.
Hosted payment page
A drop-in, PCI-friendly checkout (SAQ A) that keeps card data off your servers, included in the standard plan.
Built-in surcharging
Pass the card fee to customers where the law allows, configured right in the gateway - no separate module.
From Authorize.net to CoreGateway in three phases.
We have walked merchants and developers through this migration many times. Here is how the phases line up.
Sign up & map the API surface
Apply for CoreGateway and complete underwriting (typically 24 hours). In parallel, your dev team maps the Authorize.net SDK calls you use today to the corresponding CoreGateway REST endpoints. Sandbox is open during this phase.
Migrate the customer vault
For merchants using CIM (Authorize.net's stored-card vault), we coordinate the export and re-tokenization into CoreGateway's vault. Recurring billing customers transition without a charge interruption when scheduled correctly.
Cut over and decommission
Flip your production traffic to CoreGateway. Run a parallel period if you want extra confidence. Once your final deposits settle on Authorize.net, close the legacy account.
