API examples:

Minimum data set to create a transaction


POST /api/commerce/payment-invoices HTTP/1.0

minimum request for Corefy API = maximum request for Corefy API to create an invoice



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:

  • ADDRESS → customer [address] [full_address]
  • COUNTRY → customer [address] [country]
  • PHONE → customer [phone]
  • EMAIL → customer [email]
  • CITY → customer [address] [city]
  • POST_CODE → customer [address] [post_code]
  • BROWSER_INFO → $browserInfo
  • BROWSER_TZ_OFFSET → $browserTzOffset
  • BROWSER_SCREEN_WIDTH → $browserScreenWidth
  • BROWSER_SCREEN_HEIGHT → $browserScreenHeight
  • BROWSER_COLOR_DEPTH → $browserColorDepth
  • BROWSER_LANGUAGE → $browserLanguage
  • BROWSER_JAVA_ENABLED → $browserJavaEnabled
  • BROWSER_ACCEPT_HEADER → $browserAcceptHeader
  • BROWSER_USER_AGENT → $browserUserAgent
  • BROWSER_IP → $browserIp

Default values

If some parameters are not passed in the request to create a transaction and the corresponding constants have no values, then default values will be passed instead.

Here is the list of default values with their corresponding parameters:

  • DEFAULT_ADDRESS → 'ul testovaya d.34'
  • DEFAULT_CITY → 'Moscow'
  • DEFAULT_ZIP → '123987'
  • DEFAULT_PHONE → '79001234567'

Provider Options


  • ignore_callback
  • For cascading to work correctly, we exclude the possibility of finalizing payments using asynchronous callbacks, ignore the callback, do not change the status of the transaction on it in any way and rely only on the status request for finalization (Reconciliation)
  • use_default_browser_info
  • Is responsible for passing default values in browser data/parameters, since there may be problems in processing when we are unable to receive some data
