Description: A Fallback URL is a web address used as a backup in case the primary URL fails or is unavailable. This concept is especially relevant in the context of REST (Representational State Transfer) APIs, where the availability and accessibility of resources are fundamental to the operation of web and mobile applications. Fallback URLs allow developers and applications to continue accessing necessary data even if the primary source experiences technical issues, such as server outages or changes in URL structure. This redundancy strategy not only enhances application resilience but also optimizes user experience by minimizing downtime and loading errors. In an environment where connectivity and availability are crucial, Fallback URLs become an essential tool for ensuring service continuity and data integrity.
