Hi @Čamo
You can use API Resources which allows to choose how you want to return each field for json responses
ref: https://laravel.com/docs/8.x/eloquent-resources#concept-overview
Then, for your date fields you can use Carbon formatting methods to return the date as desired:
String Formatting: https://carbon.nesbot.com/docs/#api-formatting
Common Formats: https://carbon.nesbot.com/docs/#api-commonformats
Hope this helps.
