Async APIs: The 202 Accepted + Polling Pattern for Long-Running Operations

async-apirestpollingapi-design

The article covers the 202 Accepted + Polling pattern for async APIs, focusing on long-running operations. It details the use of HTTP 202 Accepted status code to acknowledge a request without immediate completion, along with a Location header pointing to a status endpoint for polling. The pattern is presented as a standard RESTful approach for asynchronous tasks, enabling clients to poll for completion. The source text is primarily CSS styling for a retro theme challenge, with minimal substantive content about the API pattern itself. No specific tools, versions, or benchmarks are mentioned.
