Would it be possible to develop a Sumup payment method sometime in the future. I am currently using Stripe for the event payments but have a sumup card reader for offline payments. It would be nice to be able to use just one, and the sumup fees in the UK are a lot cheaper.
While their API seems wel documented, it actually isn’t 🙂 It has a lot of unclear explanations. I’m willing to take a look at it, but I’d need a test account. If you could provide a dev-account for sumup, I can try.
I also checked out their php sdk, and it is old and no longer up-to-date with their own requirements (they require a merchant_code param, but the sdk doesn’t do that).
So unless you can find a newer sdk somewhere, this will be a no-go.
I’ve spent some hours on this:
– the php code they provide is no longer correct (paths to the API are wrong, use of merchant_code is missing)
– when correcting that, I bump into the same issue as mentioned here: https://github.com/sumup/sumup-ecom-php-sdk/issues/31 , which doesn’t receive an answer from SumUp.
