Authorize.Net

Authorize.Net is one of the most widely used payment gateways in the United States. Accept Visa, Mastercard, American Express and Discover through Authorize.Net's Accept Hosted payment page — the card is entered on Authorize.Net's PCI-compliant hosted form, never on your store, so your PCI scope stays minimal.

## Features

- Credit and debit card acceptance (Visa, Mastercard, Amex, Discover)

- Hosted payment page (PCI DSS compliant — card data never touches your store)

- Automatic auth + capture

- Signed payment webhooks (HMAC-SHA512), verified against the Authorize.Net API

- Sandbox testing environment

## Supported Currency

## Setup

1. In the Authorize.Net Merchant Interface, open Account → Security Settings → API Credentials & Keys; copy your API Login ID and create a Transaction Key.

2. Under API Credentials & Keys, create a Signature Key (used to verify webhooks).

3. Enter all three in Settings → Payments → Authorize.Net, pick Sandbox or Production, and click Test connection. Saving registers the payment webhook automatically.
