Calling SumUp from a PWA

[robwatkiss]

The iOS (v12.1) SumUp app (v2.0.4) is being opened using a sumupmerchant://pay/1.0 link and works almost as expected when using the webapp in Safari however when the same URI is called from our WebApp installed as a PWA the SumUp app it throws an error. The error text and the test URI are included below.

(native popup)
Server Error
Something went wrong! Please try again.

(app popup)
Connection Error
We lost connection to the SumUp server

(URI)
sumupmerchant://pay/1.0?affiliate-key=<affiliate-key>&app-id=com.company.basecamppos.test&amount=1.56&currency=CHF&title=Test%20Title&callbacksuccess=https%3A%2F%2Fpos.website.com%2F%23%2Fcallback%2Fpayment-success&callbackfail=https%3A%2F%2Fpos.website.com%2F%23%2Fcallback%2Fpayment-fail

The only difference here is that we are calling the link from a PWA not from Safari. We need to be able to run our webapp as a PWA as opposed to in Safari as it prevents the need to click 'open SumUp' every time and also helps us lock down the security of our POS devices.

Hi @robwatkiss

My assumption is that installing your app as a PW will create a bundle identifier that is not whitelisted for your affiliate key. Please get in touch with integration@sumup.com so we can get you up and running.

Hi @mollidor

I understand why you have closed this issue but perhaps it's worth keeping it open until we can find a resolution? I very much doubt I'm going to be the last person to be frustrated by this issue! In the mean time I've sent a message to integration@ with some more details of our integration.

Cheers,
Rob

Sorry about that. Indeed!

@robwatkiss Got any feedback?

Is there a fix? I've got the same issue.

1. Open your SumUp dashboard -> Profile -> Developers.
2. Add your app bundle identifier at the provided field
3. All Done.

Note for iOS and Expo: If using expo and your app runs in expo client, add host.exp.Exponent - the bundle id of iOS expo client.
Android uses the new API, so it's fine if you add the app-id param.

I also have this problem. I did add the bundle id in the sumup dashboard and it is working fine for android. But on iOS i always get the connection error.

@gmwilhelm Try add the App-IDs com.apple.mobilesafari and com.sumup.appswitch in the SumUp Dashboard.

@phoebusryan Thanks a lot man. You fixed my issue. Added the two App-IDs and now it works.

[phoebusryan]

@okx your welcome :)

com.sumup.appswitch is what makes the difference.
