Do you work with MapBox? I created my map using MapBox. It is time to record latitude and longitude information to the database. How can I do it. I need help.
You are better suited contacting MapBox own support and asking them if they can be integrated with Wix and how.
Although a simple search of MapBox comes up with html examples that could be put in a iframe.
Or you can work with their own API and expose your site to it.
