How to implement deeplinks in KaiOS

A user should be able to click on a link like app:this/is/some/link?with=information and the desired app opens and does some action.

This question is similar but just the other side to KaiOS - Share using WhatsApp. Another application should link to my application.

Is this possible in KaiOS?

Deeplinks do exist on KaiOS 2.5.3 or newer, but there is no documentation on them. For example, this is from the KaiStore app manifest:

"deeplinks": {
    "regex": "^(app://)(kaios-store|kaios-plus)(.kaiostech.com)($|/$|/\\?(apps|postResult)=)",
    "action": "open-deeplink"
},
"activities": {
  "open-deeplink": {
      "href": "./index.html",
      "disposition": "window",
      "filters": {
        "type": "url",
        "url": {
          "required": true,
          "pattern": "(app|rtsp|data):.{1,16384}"
        }
      },
      "returnValue": true
  },
}

The action under deeplinks points to one of the activities, which must accept a required URL parameter. An app can then register using navigator.mozSetMessageHandler to handle this activity (see B2G's Web Activities API).

That said, there is no way to deep-link to arbitrary apps. Apps must expose Web Activities in their manifest in order to be open-able by other apps.
