Firebase short links fallback link - firebase

Question

I'm using Firebase dynamic links with link shortener and I want to define fallback link for clients beside Android and iOS. Manually constructed dynamic links have parameter ofl that does exactly what I need The link to open on platforms beside Android and iOS. However it seems that this parameter is missing in shortener documentation. Although ofl is mention in the description of link parameter in shortener docs When users open a Dynamic Link on a desktop web browser, they will load this URL (unless the ofl parameter is specified).
Is it possible to somehow add a fallback url for clients beside Android and iOS (e.g. web) to redirect users there instead of link parameter

Answer 1

By using REST API
POST https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=api_key
Content-Type: application/json
{
"dynamicLinkInfo": {
"domainUriPrefix": "https://example.page.link",
"link": "https://www.example.com/",
"androidInfo": {
"androidPackageName": "com.example.android"
},
"iosInfo": {
"iosBundleId": "com.example.ios"
},
"desktopInfo": {
"desktopFallbackLink": "https://www.other-example.com/"
},
}
}

Answer 2

The simplest way to set fallback url in short dynamic link is to create long link manually and then use sdk to convert it to short one:
val longLink = "$domain/?link=$deepLink&apn=$androidPackage&ibi=$iosPackage&isi=$iosAppStoreId&ofl=$desktopFallbackLink"
FirebaseDynamicLinks
.getInstance()
.createDynamicLink()
.setLongLink(Uri.parse(link))
.buildShortDynamicLink()
.addOnSuccessListener {
val shortLink = it.shortLink
//do something with the link here
}
