Visualize upcoming Zendesk Sell Visits on a map

We are using Zendesk Sell for our CRM.
Sell has a feature to book upcoming visits.

I would like to show on a map the locations we are planning to visit in the coming days.
I am struggling with setting up the API authentication.

Can somebody guide me in setting up the authentication and getting a list of all upcoming visits?
