To change the Redis vector store retriever memory to a specific user, send a request to the following endpoint:

localhost:8000/api/{username}

Replace {username} with the desired username. This action ensures that the chatbot will only retrieve data from the Redis database specific to that user.

For detailed documentation on how to interact with the APIs in the application, visit: localhost:8000/docs

This endpoint provides comprehensive guidance on utilizing the APIs effectively.

You can seamlessly integrate this backend into your existing application, providing your users with access to a dedicated vector-based database chatbot. Remember to generate the repsective API keys.
