Firebase dynamic link support custom parameters?

Question

I am writing a App for a Open Source Conference.

Originally each attendees will receive different link via email or SMS like

https://example.com/?token=fccfc8bfa07643a1ca8015cbe74f5f17

then use this link to open app, we can know the user is which attendee by the token.

Firebase release a new feature Dynamic Links in I/O 2016, it provide better experience for users.

I had try that, but I can't find any way to pass the custom parameters (the token) in dynamic links, how to use the same link with different parameters to my users?

Thanks.

Denny, have you get the solution for this? Same scenario I am facing. — Pankaj Battise

I don't think you can use the short url: https://<my app>.app.goo.gl/Gk3m unless you create one for each user, but you can use the long url: https://<my app>.app.goo.gl/?link=https://example.com/?token=fccfc8bfa07643a1ca8015cbe74f5f17 ...(add other parameters as needed) and set new token for each user.

I assume you generate the tokens automatically. In that case you can use this to shorten the links.

@diidu how can i use in c#? please help

diidu Over a year ago

@BrijeshMavani I am not expert with C#, but my answer is completely language independent, so you can use it in any language.

sreekanth kuriyala Over a year ago

I tried in this way: https://<my app>.app.goo.gl/?link=example.com/[email protected] This is giving shortlink as https://<my app>.app.goo.gl/abcd, after decoding this short url it is coming like https://<my app>.app.goo.gl/?link=example.com/?name=test?email%[email protected] %3D is coming in place of = after decoding it.

diidu Over a year ago

@OliverDixon You don't. You change it on the long url and generate a short one if needed.

THE-E Over a year ago

Important if you want to pass more than one parameter: You have to encode your parameter list in URL e.g. param1=123&param2=321 in param1%3D123%26param2%3D321. Link: emn178.github.io/online-tools/url_encode.html

1) From https://console.firebase.google.com/ (no need for custom parameter here.)

2) Create link somewhere, f.e. on your confluence page (here we add our parameter):

https://PROJECTNAME.page.link/?link=https://PROJECTNAME.page.link/LINKNAME?PARAMETER=1&ofl=https://www.PROJECTNAME.com/

PARAMETER is your custom parameter.

ofl is a link where to go if click the link from another platform (PC, Mac).

3) Getting link data from android project Kotlin code:

Firebase.dynamicLinks
        .getDynamicLink(intent)
        .addOnSuccessListener { pendingDynamicLinkData ->
            val parameter: String =
                pendingDynamicLinkData?.link?.getQueryParameter("PARAMETER").orEmpty()
        }

That did not work for me. Maybe because I am using FirebaseDynamicLinks.getInstance() instead of Firebase.dynamicLinks?

Eugene P. Over a year ago

They have changed something (firebase guys). Now when constructing a link to click use LINKNAME?PARAMETER Instead of LINKNAME/?PARAMETER

Aleksander Niedziolko Over a year ago

This worked for me in 2021. Make sure you add your custom params after the inner link, not at the end of the main link: https://<domain>/<path>/?link=https://<domain>/<path>?PARAMETER=VALUE&apn=<appId> I was adding it after the apn, but apn is a parameter of the outer URL, and PARAMETER should be in the query of the inner URL under "link"

Aleksander Niedziolko Over a year ago

You can find your long-version dynamic link by clicking the ⋮ menu next to the link on the console, going in Link Details and using your 'Long Dynamic Link'. Add parameters to the inner link and they will come through in the app

AmitP Over a year ago

It worth mentioning the source document for this firebase.google.com/docs/dynamic-links/create-manually

Create a dynamic link
Go to link details
Copy the long dynamic link and add your parameter in the link parameter of the URL, e.g., PARAMETER=132323

https://link.projectname.com/?link=https://link.projectname.com/LINK?PARAMETER=132323&apn=com.projectname.app&afl=https://link.projectname.com/LINK

Paulo Ricardo Over a year ago

this was the right answer to me (in 2022), you have to pay attention to the whole long link and put your custom parameter at the place of PARAMETER on above URL

James Over a year ago

though it does redirect, it did not forward the custom parameters for a web url

If you want to use dynamic links with custom arguments with REST, here is an example of a payload:

{
  "dynamicLinkInfo": {
        "dynamicLinkDomain": "example.app.goo.gl",
        "link": "http://someurl.com?my_first_param=test&my_second_param=test2"
  },
  "suffix": {
     "option":"UNGUESSABLE"
    }
}

Make sure your remove 'https://' from your dynamicLinkDomain

After decoding the short URL, params afrer & symbol is not coming

Case A. If you want the short link to expand to a link with multiple parameters:

In the part where you setup a dynamic link, any parameter you append to the deep link URL will go on all platforms (web, iOS, android)

Case B. If you want to use dynamic parameters, you should use the api to create a short link

see documentation

But then customParam1 will always be 'abc' when passed to the app. How can this be dynamic?

@Silas did you find the solution, or know how to achieve dynamic parameters?

Ajinkya Taranekar Over a year ago

@Silas were you able to achieve dynamic parameters?

Shirane85 · Accepted Answer · 2017-06-21 08:43:03Z

Now you can create short links using the Firebase SDK through the FirebaseDynamicLinks.getInstance().createDynamicLink(): https://firebase.google.com/docs/dynamic-links/android/create

Sample code:

Task shortLinkTask = FirebaseDynamicLinks.getInstance().createDynamicLink()
    .setLink(Uri.parse("https://example.com/"))
    .setDynamicLinkDomain("abc123.app.goo.gl")
    // Set parameters
    // ...
    .buildShortDynamicLink()
    .addOnCompleteListener(this, new OnCompleteListener() {
        @Override
        public void onComplete(@NonNull Task task) {
            if (task.isSuccessful()) {
                // Short link created
                Uri shortLink = task.getResult().getShortLink();
                Uri flowchartLink = task.getResult().getPreviewLink();
            } else {
                // Error
            }
        }
    });

1 First Change your Dynamic Link in firebase console from http://exampleandroid/test to http://exampleandroid/test?data 2. You send the query paramter data with this

 DynamicLink dynamicLink = FirebaseDynamicLinks.getInstance().createDynamicLink()
                   // .setLink(dynamicLinkUri)
                    .setLink(Uri.parse("http://exampleandroid/test?data=dsads"))
                    .setDomainUriPrefix("https://App_Name.page.link")
                    // Open links with this app on Android
                    .setAndroidParameters(new DynamicLink.AndroidParameters.Builder().build())
                    // Open links with com.example.ios on iOS
                    .setIosParameters(new DynamicLink.IosParameters.Builder("com.appinventiv.ios").build())
                    .buildDynamicLink();

            dynamicLinkUri = dynamicLink.getUri();

You can add extra parameter to your link to generate Short URL from Firebase. Here I given example of Short URL generation using Firebase API. Here ServiceRequestHelper(this).PostCall is my generic class to make API request

String url = "https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=YOUR_KEY";

    try {
        PackageManager manager = this.getPackageManager();
        PackageInfo info = manager.getPackageInfo(this.getPackageName(), 0);
        JSONObject jsonObject = new JSONObject();
        JSONObject androidInfoObject = new JSONObject();
        androidInfoObject.put("androidPackageName", getApplicationContext().getPackageName());
        androidInfoObject.put("androidMinPackageVersionCode",String.valueOf(info.versionCode));

        JSONObject iosInfoObject = new JSONObject();
        iosInfoObject.put("iosBundleId", "tettares.Test_ID");
        JSONObject dynamicLinkInfoObj = new JSONObject();
        dynamicLinkInfoObj.put("dynamicLinkDomain", "wgv3v.app.goo.gl");
        dynamicLinkInfoObj.put("link", "https://test.in/?UserId=14&UserName=Naveen");  // Pass your extra paramters to here
        dynamicLinkInfoObj.put("androidInfo", androidInfoObject);
        dynamicLinkInfoObj.put("iosInfo", iosInfoObject);

        JSONObject suffixObject = new JSONObject();
        suffixObject.put("option" , "SHORT");
        jsonObject.put("dynamicLinkInfo", dynamicLinkInfoObj);
        jsonObject.put("suffix", suffixObject);

        Log.d("JSON Object : " , jsonObject.toString());

        new ServiceRequestHelper(this).PostCall(url, jsonObject, false, new CallBackJson() {
            @Override
            public void done(JSONObject result) throws JSONException {

                try {
                    if (result.has("shortLink")) {
                        DEEP_LINK_URL = result.getString("shortLink");                                                   }
                } catch(Exception e)
                {
                    e.printStackTrace();
                }

            }
        });


    } catch (JSONException | PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }

In Your Receiving Activity:

boolean autoLaunchDeepLink = false;
    AppInvite.AppInviteApi.getInvitation(mGoogleApiClient, this, autoLaunchDeepLink)
            .setResultCallback(
                    new ResultCallback<AppInviteInvitationResult>() {
                        @Override
                        public void onResult(@NonNull AppInviteInvitationResult result) {
                            if (result.getStatus().isSuccess()) {
                                // Extract deep link from Intent
                                Intent intent = result.getInvitationIntent();
                                String deepLink = AppInviteReferral.getDeepLink(intent);

                                // Handle the deep link. For example, open the linked
                                // content, or apply promotional credit to the user's
                                // account.

                                // [START_EXCLUDE]
                                // Display deep link in the UI
                                Log.d(TAG, "deeplink URL: " + deeplink); // Here you get https://test.in/?UserId=14&UserName=Naveen
                                // [END_EXCLUDE]
                            } else {
                                Log.d(TAG, "getInvitation: no deep link found.");
                            }
                        }
                    });

I tried all above but none work. So I think you should change the link http://example.com/?userid=123tohttp://example.com/userid/123

No need of all the hustle

Don't shorten the url if you want to pass parameters

Write the links like this.

//APP_CODE is firebase link
String link = "https://APP_CODE.app.goo.gl/?refferer=" + userId;

Intent intent = new AppInviteInvitation.IntentBuilder(getString(R.string.invitation_title))
                .setMessage(getString(R.string.invitation_custom_message)))
                .setDeepLink(Uri.parse(link))
                .setCustomImage(Uri.parse(getString(R.string.invitation_custom_image)))
                .setCallToActionText(getString(R.string.invitation_cta))
                .build();

startActivityForResult(intent, REQUEST_INVITE);

For web apps, which generating dynamic links..

const data = {
  dynamicLinkInfo: {
    domainUriPrefix: 'subdomain.page.link',
    link: url,
  },
  suffix: {
    option: 'SHORT'
  }
};
return fetch(`https://firebasedynamiclinks.googleapis.com/v1/shortLinks?key=${environment.firebaseConfig.apiKey}`, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify(data),
}).then(res => res.json()).then(response => response.shortLink).catch(console.error);
