A 429 Too Many Requests error occurs when an application exceeds the allowed rate of requests to a server within a given timeframe. This issue can arise from various factors, including a high volume of users or rapid script execution.
When this error is received, it usually signifies that the API request has been blocked due to exceeding the limit. The exact behavior and impact vary depending on the specific service, its configuration, and the application using it.
Common strategies for handling 429 errors include implementing rate limiting, increasing the allowed requests per unit of time, or employing techniques such as idempotent requests and caching to reduce the load on the server.
