Add from/to parameters to URL-scheme

We'd like to launch the AtB app from our Where To? app with a start / destination coordinate pair like this:

atb://?start=59.936215,10.659893&destination=59.741888,10.151612

optionally with a title for start and destination. Is this supported?

I'd name the parameters something related to coordinates though since we have more than one way to represent "from" and "to". NSR stop place ids for example.

Unsure if we have the ability to represent something as a "coordinate" in the UI though. We'd probably have to reverse-lookup location with geocoder so the search boxes has a representable text. The only thing (afaik?) that accepts just a pure coordinate is "My position" (GPS on device).

Probably also a good idea to specify the screen, like atb://travel or something. Seeing as we have more screens that could take a coordinate or NSR id, like "Departure" and "Map".

But in that regard one could support different schemes and query parameters:

• atb://travel?fromLatLng=59.936215,10.659893&toLatLng=59.741888,10.151612
• atb://travel?fromQuery=Prinsens%20gate%2039&toQuery=City%20Syd
• atb://travel?fromLatLng=59.936215,10.659893&toNsr=NSR:StopPlace:41617
• atb://departures?fromNsr=NSR:StopPlace:41617
• atb://map?fromLatLng=59.936215,10.659893

@cbrevik Agreed! I was thinking we could make some suggestions á la this to @futuretap when we got to it, but you are way ahead of me :D

The atb://travel?fromLatLng=59.936215,10.659893&toLatLng=59.741888,10.151612 scheme looks good. I suggest adding optional fromName and toName string parameters for display purposes. A reverse lookup usually returns only the address but our users deal with POI names.

Once that deeplink is done, we could probably set up a ticketing shortcut as well. Should probably start with single tickets, that doesn't need the user to be logged in.
