I need to import a train and bus ticket into the Google Pay app. Currently, there are only options for a flight boarding pass.
There are also API's called 'Google Pay APIs for India', which got this feature, but I doubt about using it (because I'm not from India).
What should I use to add a ticket for bus or train to my customers Google Pay app?
You must use Google Pay Transit Passes :
