#parsed_response ⇒ Object

Every TapPay endpoint answers with a JSON object, so a body that is not one means something other than TapPay replied - a maintenance page, a proxy, a WAF. Returning the raw body instead turned parsed_response['status'] into a String#[] substring search, which answers nil without complaining. Raise rather than hand back something that reads like a result.

#success? ⇒ Boolean

TapPay signals business failures (declined card, insufficient funds, expired card) with HTTP 200 and a non-zero status, so the HTTP code alone says nothing. Client only builds a Response once validate_response has accepted the HTTP code, so status is the only question left.

This means "TapPay processed the request", not "the money moved": for a credit card the transaction is authorised but capture is asynchronous, and for LINE Pay / JKO Pay / iPass Money it means only that a payment_url was created and the customer has yet to pay. Confirm with Transaction::Query.

Returns:

  • (Boolean)
