I am going through the API, but I have a question.
currently building a marketplace app :
I understand that OathAPI allows you to ‘drive’ users for them to create sellers account on SquareUp via, I guess an Webview Url redirect.
But in the developper reference, the Customer api allows to create custom customers and store their personal details as well as their credit cards. Would it be then possible for us just to use this API, create our own sellers, and process payments VIA Square ? Would that represent too much of a fraud threat for squareup ?
Another question, as I am reading through the Flutter pluggin, I have noticed that there is no mention of 3Dsecure2 call backs, are you guys planning to include it ?
Last but not least. When Squareup holds customers from an app, how long does it take for them to cash out ?
Thank you for all your help
