Provider Options

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 → If the value is true, then the browser data is taken from constants. If the constants have a no values, then the browser data is taken from default values.
