Opencart 2.3集成Authorize.net AIM测试模式货币代码报错求助

Hey there, let's walk through the most common fixes for that currency code error you're seeing with Authorize.net AIM on OpenCart 2.3 in test mode:

• Verify Authorize.net Sandbox Currency Support
  Authorize.net's sandbox accounts don't support all currencies by default. Log into your Authorize.net sandbox dashboard, navigate to Account Settings > Payment Form > Currency Settings, and make sure the currency you're using in OpenCart is enabled here. USD is always a safe test currency to start with if you're unsure.

• Double-Check OpenCart Currency Configuration
  Head to your OpenCart admin:

  • Go to System > Localisation > Currencies
  • Ensure the currency you're using has a valid, uppercase ISO code (e.g., USD, EUR—no typos like usd or Usd)
  • Confirm the currency's Status is set to Enabled
  • For test mode, set the exchange rate to 1.0 if you're using the base currency (this avoids conversion issues)

• Inspect Authorize.net AIM Extension Settings
  Some older versions of the Authorize.net AIM extension for OpenCart 2.3 have a dedicated "Allowed Currencies" field. Check your extension's configuration page to make sure your target currency is added to this list. If there's no such field, the extension might be hardcoding a default currency—try switching your store's default currency to USD temporarily to test.

• Test with a Default Currency
  As a quick sanity check, switch your OpenStore's default currency to USD (System > Settings > Edit Store > Local), then run another test payment. If the error goes away, the problem is definitely with your original currency not being supported by your Authorize.net sandbox account.

• Check Extension Compatibility
  OpenCart 2.3 is an older version, so the Authorize.net AIM extension you're using might have compatibility bugs around currency handling. Look for an updated version of the extension specifically built for OpenCart 2.3, or check the extension's support forum for similar reported issues.

• Dig into Logs for Details
  Enable error logging in OpenCart (System > Settings > Edit Server > Error Logging set to Yes) and check your Authorize.net sandbox transaction logs (Reports > Transaction Details). This will show you the exact currency code being sent to Authorize.net, so you can confirm if it's mismatched or unsupported.
