Introduction: The Challenge of Whitelisting Parameters

Firebase Dynamic Links provide a powerful way to create short links that can redirect users based on various conditions such as device type or whether the app is installed. However, many developers encounter difficulties when trying to include query parameters in their dynamic links.

One common issue is the inability to whitelist specific parameters. For instance, consider the case where a developer tries to create a dynamic link like:

[[See Video to Reveal this Text or Code Snippet]]

This URL should redirect to a deeper link within the app, but when tested, the developer receives a warning that the format of the parameter invitedBy is not whitelisted for the domain.

In this post, we'll explore the problem and provide effective solutions to manage parameters in Firebase Dynamic Links.

Understanding the Problem

The primary issue lies in Firebase Dynamic Links' handling of query parameters. When you set up your dynamic link configuration for a specific domain, you need to ensure that all components, including parameters, are properly whitelisted. Here are key points to remember:

Dynamic Links: Designed to be short and static, typically not allowing for custom query parameters.

Whitelisting Requirements: Firebase requires specific format and matching patterns for whitelisting parameters.

As indicated in the example, even after setting the rule, parameters like invitedBy may still trigger warnings, indicating they're not recognized by Firebase.

Dealing with Dynamic Link Limitations

Given that Firebase Dynamic Links do not support query parameters directly, what can you do? Here are some approaches:

1. Create Individual Links Programmatically

If your use case demands that you pass different values for a parameter like invitedBy, you might need to create individual short links for each unique value. This can be done using the Firebase API programmatically:

Fetch the parameter value you want to include.

Programmatically generate a unique link for each value to be whitelisted.

2. Implement a Custom Redirecting Server

Since whitelisting parameters in Firebase Dynamic Links can be cumbersome, consider creating your own solution:

Set Up a Web Server: Implement a custom server that can handle the short link logic more flexibly. This server can accept your custom short link containing parameters and redirect to the appropriate long URL in Firebase Dynamic Links.

Redirection Logic: When a user accesses https://links.myapp.com/invite?invite..., your web server can process the request and generate the actual Firebase link. This method allows you to:

Maintain social media tags.

Detect installed apps for deep linking.

Redirect non-mobile users to specific landing pages.

Example of a Redirection Logic:

User clicks on your custom short link.

The server extracts the invitedBy parameter and formats it into the Firebase link.

The server then redirects the user to the actual deep link based on the logic you've set up.

Conclusion: Navigating Firebase Dynamic Links with Parameters

While Firebase Dynamic Links offer great capabilities, managing them effectively when it comes to parameters like invitedBy can be tricky. By either creating individual links or implementing a custom redirection server, you can work around the limitations imposed by Firebase.

Remember, the goal is to create a seamless experience for your users while ensuring that all necessary information can be passed through your links. With these strategies, you can confidently utilize Firebase Dynamic Links without running into parameter whitelisting issues.
