Building a universal/app link application

Let's specify our requirements.

I would like to build a simple web application to serve as a replacement for Firebase's dynamic link functionality. 
Here are the requirements:

1. App Link Generation Endpoint
Input: API Key, Fallback URL, Additional Data
Output: A unique app link in the format https://domain.name/<unique_code>, 
where <unique_code> is an 8-character alphanumeric string.

The mapping should be stored in a database table with relevant indexing.

2. App Association Endpoints
The application should serve the following files for app association:
Android: https://domain.name/.well-known/assetlinks.json
iOS: https://domain.name/.well-known/apple-app-site-association

3. App Link Retrieval Endpoint
If mobile apps successfully intercept the link, they use this endpoint to retrieve Fallback link and Additional data.
Input: API Key, Unique Code
Output: Fallback URL, Additional Data

4. Redirection Logic
If the app link is not intercepted by a mobile app, users should be redirected to the specified fallback URL.
