how to get distance between to location with the help of Wix Address input ?

?

A straight direct distance (beeline)?

You need to use an external API where you provide 2 point (lat, long) and it will return the distance (beeline) or distance (car’s route)

I believe Wix made a video about using the distance matrix API a while back. Look on youtube or Wix Velo examples
