Cwa-documentation: Link structure for other contact tracing apps

[ZengineChris]

Link structure for other contact tracing apps

I followed the documentation here and end up with this URL:

```` bash
https://checkin.uninow.com/N74-62-PG-R7-3#/CWA1/CAESKwgBEhBHZWJ1cnRzdGFnc2ZlaWVyGglNYWdkZWJ1cmco872EhAYwgNqEhAYadggBEmCDAszMTXne1DAA5_YxmhRdd_NZN2VKl9L32Jl9-ZybE4b2eNIrhFOKYU4XAOHq3RPLDxdHTW6ANiO24rCOO4rj06HzcVZy3pel58-L1KSPG-_PneL2BoyZQRz3qlu2hoAaEIl9MOnm2oxyxXUdBqkB_wkiBAgBEAs

````

The payload in this URL is from a QR Code generated by the CWA app. Before I tested this payload I have tried different others generated with the proto definition from the same documentation page. 

I generated different QR codes with this link and always get an INVALID_URLerror from the app. 
Did I miss something? Or is there a way to get a more detailed error message?

Yes every host needs to whitelist via remote config for the app.
Please send a short explanation about your app and distribution in german to:

Thank you for your quick response @thomasaugsten

Any updates on this?

@thomasaugsten Has the Luca app already requested whitelisting of their app?

Their latest version added support for reading QR codes like this:

(encodes https://app.luca-app.de/webapp/81d9e1db-7050-4557-b1ca-a9e4fe899bd9#e30/CWA1/CAESLAgBEhNEb2xvcmVzIGN1bHBhIHV0IHNpGhNOb3N0cnVkIE5hbSBpZCBlbGlnGnYIARJggwLMzE153tQwAOf2MZoUXXfzWTdlSpfS99iZffmcmxOG9njSK4RTimFOFwDh6t0Tyw8XR01ugDYjtuKwjjuK49Oh83FWct6XpefPi9Skjxvvz53i9gaMmUEc96pbtoaAGhDL1rYQOi3Bh_YYps7XagWYIgcIARAIGIQF )

At the moment the CWA displays "Invalid URI - no matchedDescriptor"

As far as I know they so far do not generate these QR codes that are compatible with CWA, but are planning to do so as soon as the new versions of their apps are rolled out to more people. See also https://gitlab.com/lucaapp/android/-/issues/32

[thomasaugsten]

Yes they also requested a whitelisting but so far no app is whitelisted.

@thomasaugsten @mlenkeit
Maybe it would be helpful to add to https://github.com/corona-warn-app/cwa-documentation/blob/master/event_registration.md that for interoperability apps need to be whitelisted

FYI here: https://github.com/corona-warn-app/cwa-server/pull/1362/commits/a7b80cb2d1b68231e7250d54408f3ba486751ff9

@floscher Luca seems to be whitelisted from CWA 2.1 on: https://github.com/corona-warn-app/cwa-server/pull/1362/commits/a7b80cb2d1b68231e7250d54408f3ba486751ff9
So, after that it's up to Luca when they finisch iOS and web frontend for interoperability

Edit: @Ein-Tim "the blitz" was again faster than everyone ;)

[floscher]

Great, thanks for the update.

[thomasaugsten]

This is changed in code but this server is not deployt yet

@thomasaugsten

The commit is actually part of the PR https://github.com/corona-warn-app/cwa-server/pull/1362 which isn't even merged yet, so nothing actually changed already. Sorry for the confusion (:
