Additional information



If some parameters are not sent in the transaction creation request, they will take the values from the set constants.

Here is a list of constants with their corresponding parameters:

  • FULL_ADDRESS → customer [address] [fullAddress]
  • REGION → customer [address] [region]
  • COUNTRY → customer [address] [country]
  • CITY → customer [address] [city]
  • POST_CODE → customer [address] [postCode]
  • EMAIL → customer [email]
  • NAME→ customer [name]
  • PHONE → customer [phone]
  • LANG → language

Provider Options


  • finalize_by_protocol
    • The provider does not guarantee the finality of the fail status because in their system it can later change to success and if the merchant does not agree with this logic then there is no need to enable this option.
      • Then we (Corefy) will stop failing payments but the merchant will not receive transaction status discrepancies.
    • If a merchant wants to fail decline which the provider does not guarantee then you need to enable this option.
