Hello community!
This is my first comment and I would like you to help me know if it is possible to mark a start and finish point on a map.
I appreciate your attention and response.
Hey!! Welcome to Thunkable!
It is possible to mark a start and finish point in an app. However if you want to get the blue line you often see in Google Maps, Waze, etc. You need to use an API ( Here or Google Maps). How it works, you need to provide a starting point (lat, long) and a destination point (lat, long). The API will provide you with directions and a polyline.
This polyline is a series of lat and long coordinates that make up the actual line you see in a map. On Thunkable’s component, you can trace a line with coordinates. 
Let me know if you need any more help or guidance! Look for the ‘Here API’ or ‘Google Map API’ documentation so you see what I mean by the polyline and all 
Welcome!!

Hello Sofia! Thanks for the reply 
Please could you tell me where I place “Here API” or “Google Map API” so I can read the instructions and add it to my thunkable app block. 
Sure here are the links:
Here is an example of a request using the Here APi 
The components you need in Thunkable are Web API and the Map
