URL scheme to show the vaccination certificate?

[hansemannn]

Hi there!

Very quick question: Is there an URL scheme, yet to directly open the vaccination certificate from other apps? We have a travel app where many users requested a feature already to open the certificate from our app and likely many other apps will be interested in this as well (to have a common shortcut to the pass). Thanks in advance!

Best,
Hans

P.S.: If not available, yet, I'd be happy to implement it, but it'd be good to know if such a change is welcome in this repo.

@hansemannn there's no support for a URL schema at the moment that would allow to open the vaccination certificate from other apps.

Has your question been answered?

I'd suggest you open a new "Enhancement Request" issue, requesting to add an URL schema. Best would be if you mention there that you'd be willing to implement this.

Have a nice Sunday.

+I think it would be cool to have something like hc.coronawarn.app/check_certificate?start=1633260123&end=1633353723&country=de&senderUrl=mytravelapp.com/hccertprovider/tokenService?token=$TOKEN which makes the CWA make a request to mytravelapp.com/hccertprovider/tokenService?token=lv8l6rlx3rm4kwuqci86. The requesting app returns hc.coronawarn.app/check_certificate?token= lv8l6rlx3rm4kwuqci86 then the CWA asks the user for permission to send the certificates name and DoB (the user can select which certificates to send) to the app mytravelapp.com and then returns

{
	"1":
	{
		"status": "valid",
		"type": "vaccination",
		"name":
		{
			"given": "Max",
			"family": "Mustermann",
			"transliterated":
			{
				"given": "MAX",
				"family": "MUSTERMANN",
			},
		},
		"dob": "1999-05-21",
	},
	"2":
	{
		"status": "valid",
		"type": "test",
		"name":
		{
			"given": "Martha",
			"family": "Mustermann",
			"transliterated":

				"given": "MARTHA",

		},

	},
},

I had the same question recently. I would like to add a Shortcut (Kurzbefehl) on my Homescreen to quickly access my vaccination certificate via a url scheme (e.g., corona-warn-app://certificates).
Any reason why this isn't implemented?
Seems like some low-hanging fruit to improve the app!

To add to that, it might be an interesting application to have an NFC tag (with this url scheme embedded) near certificate checkpoints to provide an easy shortcut for users to view the certificate QR code for scanning.

As a user, I can tap my phone on the NFC tag and have the CWA immediately open and display my newest vaccincation/valid test certificate.

Maybe you should transfer this issue to ehn-dcc-development/hcert-spec cause if this would be implemented, it should work with every wallet app.

@dsarkar / @hansemannn

I suggest to close this issue as the question which was asked in the OP has been answered by @mlenkeit.

Let's convert it to a feature request! 💻

[Ein-Tim]

@moabits I suggest you open a new issue in the https://github.com/corona-warn-app/cwa-wishlist for this, as if implemented, it should be implemented for both, iOS & Android.
