Is it possible to specify the short link with Firebase Dynamic Links?

Question

This question is about what I think is a discrepancy between the REST API (from the docs anyway), and the behaviour afforded through the Firebase console.

Here's the console:

Yet when I look at the REST API docs, I don't see any way to follow step (1) from the Firebase console. I don't see any way to set up a short URL link, rather it looks like it will be generated. This is a shame because I wanted to generate guessable links. For reference, here is their specification sans platform-specific info keys (eg "iosInfo"):

{
  "dynamicLinkInfo": {
    "domainUriPrefix": string,
    "link": string,
  },
  "suffix": {
    "option": "SHORT" or "UNGUESSABLE"
  }
}

Is there a way to copy the console behaviour through the API?

Answer 1

I was able to create persisting link in firebase dynamic link using API in node. I did the following.

1. Create oauth2 client

import {google} from "googleapis";

const oauth2Client = new google.auth.GoogleAuth({
    keyFile: "path to service account json file",
    scopes: ['https://www.googleapis.com/auth/firebase']
})

2. Create link data object

    const data = {
        "dynamicLinkInfo": {
            "domainUriPrefix": "https://myapp.page.link",
            "link": "my deeplink",
            "androidInfo": {
                "androidFallbackLink": "",
                "androidLink": "",
                "androidMinPackageVersionCode": "",
                "androidPackageName": bundleName // android package name, fe my.app.io
            },
            "iosInfo": {
                "iosAppStoreId": `${isi}`, // app store app id
                "iosBundleId": bundleName, // ios app bundle id, fe my.app.io
                "iosCustomScheme": "",
                "iosFallbackLink": "",
                "iosIpadBundleId": "",
                "iosIpadFallbackLink": ""
            },
            "navigationInfo": {
                "enableForcedRedirect": false
            },
            "analyticsInfo": {
                "googlePlayAnalytics": {
                    "utmCampaign": "",
                    "utmMedium": "",
                    "utmSource": ""
                },
                "itunesConnectAnalytics": {
                    "at": "",
                    "ct": "",
                    "mt": "",
                    "pt": ""
                }
            },

            "socialMetaTagInfo": {
                "socialDescription": "",
                "socialImageLink": "",
                "socialTitle": ""
            },
        },
        "name": "Link name column from FDL",
        "suffix": {
            "customSuffix": "URL_prefix_during_link_creation_from_FDL, "option": "CUSTOM"
        }
    }

3. Call the API

oauth2Client.request({
        method: "POST",
        url: "https://firebasedynamiclinks.googleapis.com/v1/managedShortLinks:create",
        data: data
    })

As far as I know, you cannot use any direct REST API since you need appropriate oauth2 access_token for specific scope. I was trying to spoof FDL requests and reflect it behaviour without success, but this works.
