关于ARBCreateSubscriptionRequest银行卡有效性验证的技术问询

Great question! Let's break down how card validation works with the ARBCreateSubscriptionRequest endpoint, especially compared to the validationMode in Customer Profiles:

默认自动验证，无需额外参数 #

Unlike Customer Profiles where you explicitly set validationMode to control card checks, the ARBCreateSubscriptionRequest automatically validates the payment method (including those passed via opaqueData) by default. This is built into the endpoint's core logic—since recurring subscriptions depend on having a valid, active payment method for future charges, validation is non-negotiable here.

验证的具体内容 #

When you submit the request, Authorize.net runs several key checks:

• Basic format validation (e.g., valid card number length/Luhn check, valid expiration date)
• Issuer-level verification to confirm the card is active, not blocked, and eligible for recurring transactions (this usually involves a $0 or $1 authorization hold, which is immediately reversed if successful)
• CVV verification (if provided) against the issuer's records

无效卡的响应处理 #

If the card or payment token is invalid, the API will return an error response with a specific code and human-readable message. Common examples include:

• E00003: Invalid credit card number
• E00019: The credit card has expired
• E00027: The transaction has been declined

Here's a snippet of what an error response might look like:

<ARBResponse>
    <messages>
        <resultCode>Error</resultCode>
        <message>
            <code>E00019</code>
            <text>The credit card has expired.</text>
        </message>
    </messages>
</ARBResponse>

Key Takeaway #

You don't need a dedicated validationMode parameter here—validating the payment method is a fundamental step of creating a recurring subscription. The endpoint will fail fast with clear errors if the card is invalid, so you can catch and handle these cases in your code before finalizing the subscription setup.
