Credit Limit Validator

Overview

The Credit Limit Validator checks whether the customer has enough available credit to cover payments that require credit. It supports three levels of validation: credit denied, insufficient remaining credit, and exceeded credit limit. Stores can optionally be configured to show a warning instead of blocking the order when credit is insufficient.

Identifier

Behavior

1. Looks up the customer associated with the cart
2. Identifies payments that have RequiresCredit enabled in the payment configuration
3. Calculates the total credit demand from all credit-based payments
4. Checks three conditions in order:
   • Credit denied: If the customer's IsCreditDenied flag is set, returns an error
   • Insufficient remaining credit: If CreditRemaining is less than the total credit demand, returns an error (or a warning if the store has OnlyWarnOnCreditLimit enabled)
   • Exceeded credit limit: If CreditLimit is less than the total credit demand, returns an error
5. If no credit-based payments exist or the customer has sufficient credit, validation passes

Store-level override

If the store has the property OnlyWarnOnCreditLimit set to "true", insufficient credit will produce a warning instead of an error, allowing the order to proceed.
