I tried using delay(50) on each API call, but I still get 429 Too Many Requests. Back-end is Laravel, what’s the best way to prevent this in Angular or should this be handled by back-end Laravel?

this is my first time posting a question here. I am a beginner here. I am searching about how to use laravel in my angular project, but I can’t seem to find a tutorial that do this. All of the tutorials that I watched is from years ago, can you provide me resources or steps that I can follow? Preferably a youtube tutorial.
