How can I make an API call to a website, obtain a Bearer token, store it in the browser, and use it for subsequent requests? [closed]

I’m working on a web application where I need to make an API call to a website, obtain a Bearer token from the response, store it in the browser (e.g., in local storage), and then use this token for subsequent API requests.

Could someone guide me through the best practices for implementing this securely and efficiently? Any code examples or detailed explanations would be greatly appreciated!

I have implemented an API call using fetch in JavaScript and successfully retrieved the Bearer token from the response. I stored the token in local storage using localStorage.setItem(‘token’, token). However, I’m unsure if this is the most secure approach, and I’m also having trouble figuring out how to use the stored token in subsequent API requests.

I was expecting to securely store the token and seamlessly use it for future API calls without manually passing it every time. I’m looking for best practices on how to achieve this, especially considering security concerns like token expiration and potential vulnerabilities.
