**Automating Refresh Tokens for Improved User Experience**

In a recent blog post, developer difficultworld24 shared a clever solution to automate refresh tokens in Axios interceptors. The issue arose while working on a React.js project interacting with the Salesforce API, where access tokens are valid for only 24 hours. To overcome this limitation, the author implemented a middleware that checks for 401 responses from API endpoints and re-initiates the access token by calling the refresh token API.

**Key Takeaways:**

* Automating refresh tokens eliminates unnecessary API calls to Salesforce OAuth.
* The solution involves attaching a middleware to every request made by Axios, checking for 401 responses, and re-initiating the access token when necessary.
* This approach improves user experience by avoiding interruptions and prompts to reload the page.
