Visa Checkout API iOS/Android - Multiple merchants in one single App
My scenario is the following: My App must have several merchants, each one with your own account, and the users must to be abble to buy from each one of them. So, the App must to be abble to switch between several vendors account identifiers while the App is running (execution time).
I would like to know if is possible to have multiple merchants identifiers in one single App (one single apikey) using Visa Checkout API to iOS and Android. Is that possible? Or must each App have just one vendor?
If it is not possible with Visa Checkout, is there another API that Visa can offer me to process payments like described above?
