Authorize.Net Deprecation: Keep Acumatica Payments Running with CPay

Acumatica ERP Action Required

Authorize.Net Classic Is Being Deprecated. Is Your Acumatica ERP Ready?

If your Acumatica deployment still relies on the classic Authorize.Net integration, you need a migration plan — and CPay makes it seamless.

Authorize.Net has announced the deprecation of its Classic API and older payment gateway integrations. For businesses running Acumatica ERP with the native Authorize.Net connector, this is more than a minor update — it is a forced migration that, if left unaddressed, will break payment processing entirely.

This is not a distant future problem. The sunsetting of Classic integrations is already underway, and organizations that delay the transition risk payment failures at the worst possible time — during invoicing cycles, month-end closes, or customer payments.

What Is Actually Changing?

Authorize.Net is deprecating support for its older AIM (Advanced Integration Method) and SIM (Server Integration Method) APIs in favor of the newer Accept.js and API 2.0 standards. These older methods underpin many out-of-the-box ERP payment integrations, including legacy Acumatica connectors.

The impact for Acumatica users specifically includes:

  • Credit card tokenization workflows breaking at the gateway level
  • Saved customer payment profiles becoming inaccessible or non-chargeable
  • Auto-pay schedules for recurring invoices stopping without warning
  • Payment capture failures on sales orders and AR invoices
  • Refund and void transactions returning errors

Why the Native Acumatica Connector Falls Short

Acumatica's built-in payment gateway framework is designed for basics. It handles authorization and capture but offers limited support for advanced scenarios such as stored payment methods per customer, multi-currency processing, level 2/3 card data, and real-time surcharging rules.

When a gateway like Authorize.Net updates its API, ERP vendors typically need months to certify and release an updated connector. During that window, your business is exposed. More fundamentally, the native connector does not provide the gateway-agnostic flexibility that modern payment operations require.

"The rule of thumb: if your payment processing is tightly coupled to a single gateway built into your ERP, you are one deprecation notice away from a critical outage."

How CPay Solves This for Acumatica

CPay is Contrivya's purpose-built payment add-on for Acumatica ERP. Rather than depending on a single gateway's native connector, CPay provides a gateway-agnostic payment layer that sits natively inside Acumatica's AR, Sales Order, and Payment modules.

When Authorize.Net Classic is deprecated, CPay users switch gateways from within Acumatica's configuration screen — no code changes, no ERP upgrade, no downtime. The following capabilities ensure business continuity:

Gateway Agnostic

Switch between Authorize.Net, Stripe, Braintree, and others without touching your ERP configuration or workflow.

Stored Payment Profiles

Securely vault customer cards on file and charge them directly from AR invoices or scheduled billing runs.

Recurring Billing Support

Auto-pay schedules and subscription invoicing remain intact during and after gateway migrations.

PCI-DSS Compliant

Card data never touches your Acumatica server. CPay uses gateway-level tokenization to maintain full PCI scope reduction.

Migration Path: From Legacy Authorize.Net to CPay

The typical migration for an existing Acumatica customer takes between one and three business days, depending on the volume of stored customer payment profiles that need to be re-tokenized in the new gateway. Contrivya's implementation team handles the full process:

  1. Discovery call: Audit current payment workflows, gateway dependencies, and transaction volumes
  2. Gateway selection: Choose the replacement gateway that fits your processing volume and card types (Authorize.Net modern API, Stripe, or others)
  3. CPay installation: Deploy CPay add-on to your Acumatica instance (cloud or on-premise)
  4. Profile migration: Re-tokenize stored customer payment methods under the new gateway
  5. Parallel testing: Run test transactions in parallel with existing setup before cutover
  6. Go-live: Switch live traffic to CPay — zero ERP downtime required

Is CPay Right for Your Business?

CPay is ideal for Acumatica customers who:

  • Currently use Authorize.Net Classic and need a migration plan
  • Process more than 50 customer payments per month and want to reduce manual effort
  • Run subscription billing, service contracts, or recurring invoice schedules
  • Need to accept cards directly from the AR Invoice screen without leaving Acumatica
  • Want gateway flexibility so a future change never disrupts operations again
