Simple Checkout Validator

Block checkouts with special characters, invalid postal codes, or too many characters.

Block checkouts that include special characters, use non-permitted postal codes, or have too many characters. We use the Cart and Checkout Validation Function and do not store any personal information on our app's server. This feature is available to merchants on plans other than Shopify Plus.

• Character Limit Function
• Function to trigger an error when specific phrases are included
• Function to set a list of valid postal codes and error out all others.
