Customer Exists (Fast Check)

Returns whether a customer already exists in the account.

The data to be submitted to the API is composed of the following fields:

Notes:

• Either the card_number, customer code, customer_username, or customer email is REQUIRED.
• Use any combination of parameters. Success will only be returned if ALL passed parameters are matched. (ie. you can validate on card_number + email or customer_username + code, or on all parameters card_number + code + customer_username + email.)
• If passing the customer code, this MUST be the unique Customer ID that was either
  • passed as 'code' by your program when the customer record was created previously, or
  • the 16-digit number that was generated by us and returned to you in the API response.
