The country_change callback
With KCO Global, an optional server-side callback, country_change is available.
NOTE: Multiple callbacks for a refine call should not be made. If you have already called address_update, do not also call
country_change callback works as the address_update and shipping_option_update callbacks.
It uses the same:
- Error handling
as the other callbacks.
When to use
The country_change callback should be called when the billing address country is changed.
With KCO Global, all callbacks include these features:
- currency is part of the payload
- currency can be updated by the merchant
- a 3xx redirect url is available (as for order validation callback)
