The “Too Many Requests” error with code 429 typically occurs in web development when an application receives an excessive number of API requests within a specified timeframe. This often happens due to insufficient rate limiting measures, overwhelming server resources, or misconfigured APIs.
To address this issue, developers should implement effective rate limiting strategies such as exponential backoff and/or request batching. Additionally, upgrading underlying infrastructure with high-performance servers is crucial for handling increased traffic without degradation in service quality. Proactive error handling and monitoring are essential to prevent system overload and ensure smooth operation under varying loads.
