I have integrated the Square POS SDK into our test app as described here.
I would like to know, when our app initiates a checkout on the Square Terminal, how does the app get notified when the checkout has completed?
Presumably, the app polls a Square API/endpoint to monitor for checkout completion, but which of Square’s APIs/endpoints does it use? And how often does it poll it?
I would like to know this as we will ultimately be using the Terminal API instead of the POS SDK, so we will need to recreate whatever technique the POS SDK uses for polling.
Thank you.
