Is it possible to open PayPal Here with a particular invoice or payment amount pre-populated? I am trying to enable a smooth workflow from a mobile web app to PayPal to swipe a credit card.
For example, can you create a deep link into the PayPal Here app? Or notify the PayPal REST API to open a recently created invoice directly?
You can try this Sideloader Api. It also have 3 samples project that will get you started.
