Payment retry behavior should be documented

[anssih]

The documentation should explain the recommended client behavior when the user wishes to retry a payment. E.g. should a new payment be always created (with a different stamp), or can the client store the original response so it can re-show the buttons later, or something else?

The legacy API contained the paymentURL field which allowed retries by directing the user there, but I do not see similar functionality in the new API. Unless it is the "href": "https://api.checkout.fi/pay/80621392" field in the example response which seems to not be documented?

(client = merchant server, user = merchant's customer)

Thanks for the input. We will update the documentation and consider adding support for payment retries.
