I am trying to develop a wrapper for the Square Connect API. I am looking for a sandbox account or a way to import test data to a new account so I can get started quickly wi
For future reference for people who land here from Google, Square now offers this. Every account is given a set of sandbox credentials, as well as there is an anonymous sandbox you can use without logging in.
Login here and create an application. Once you create the application, there will be Sandbox settings that you can use. https://connect.squareup.com/apps
Here is some more documentation: https://docs.connect.squareup.com/articles/using-sandbox/ https://docs.connect.squareup.com/ (general guide)
Unfortunately it doesn't seem like there is a dashboard where you can see the transactions in Sandbox mode, but I suppose it's not 100% needed.
You can download the Square register app on a mobile device and submit cash transactions to a live merchant account. Not ideal, but this is what I do to add test data.
