Validation Types

Each use case doc covers two types of validations:

  • Field Level Validations: Rules and messages triggered when a specific input field fails validation (e.g., required field, invalid format).
  • Form Level Validations: Messages triggered at the form-submission level for cross-field or server-side scenarios (e.g., duplicate payment method).

Payment Methods Covered

Each page documents validations for the following payment method types:

  • Bank Account (ACH) — including telephonic entry where applicable
  • Card — including telephonic entry where applicable
