Check if Invoice can be refunded online programmatically

Question

Is it possible to check programmatically if an given invoice can be refunded online via a payment gateway like Paypal/Braintree?

Answer 1

For anyone having a similar requirment my solution was to check the following:

• Can the invoice be refunded ($invoice->canRefund())
• Does the invoice have an transaction id ($invoice->getTransactionId())

Please note, that this doesn't verify if the gateway does support online refunds (e.g. Paypal/Braintree supports it)

I didn't find any other solution and I'm still open for alternatives.
