PxPay supports authorize but not capture?

As the title says pxpay seems to support authorize but not capture.

That's not uncommon unfortunately. I was just working on another gateway plugin and their gateway API doesn't support capture either. You can do an authorize but then you either have to void it or let it expire, you can't actually capture it.

If the PxPay API supports capture then I'm happy to process a PR for it.

Ah I've found the relevant docs in the integration guide

Please note that a complete transaction cannot be submitted via PX Pay 2.0, as the PX Pay 2.0 API is designed for the initial capture of card data only.
The Complete transactions will need to be processed manually using the Payline account (included with each PX Pay 2.0 account).

I'm not sure if I'm being a bit silly here but is it worth adding that snippet to the readme to explain what to me at least seems like a weird situation?

I would document this either in the README or in the class docblock of the relevant gateway class, under a section titled QUIRKS. This is the approach I've used in the past.

I think the intention is you use PxPost (or PXWS, or Payline) to capture the auth. You use getTransactionReference() to get the authorisation from completeAuthorize(), then call capture() on the PxPostGateway using that reference (assuming you're set up for PxPost and PxPay).

Similarly, voids are done through PxPost using refund().

This is documented in the PxPay documentation on page 26 (FINALIZING AUTH TRANSACTIONS -> Option 4-5: PX Pay 2.0 > PX Post/Webservice), so I wouldn't say it's a quirk...

Well, it's quite different to what a lot of other gateways do, so that's one of the things that I normally include in the gateway documentation under "quirks", even if it is documented. I'll leave this open in case someone wants to submit a PR to tidy up the package documentation to include such a note.
