This plugins waits for a danish zip-code to be entered, then calls the below-explained API to convert the zip-code to a city-name, therefor making the default checkout easier for danish customers.
https://dawa.aws.dk is a public API by the danish government division “Styrelsen for Dataforsyning og Effektivisering”.
It is free to use and provides (in this case) a conversion of ZIP-code to City-Name in denmark.
