VerifiedA webhook is essentially an HTTP callback: after a repository detects an event such as a code push, it sends a POST request to a pre-configured URL.84% similarUnverifiedWebhooks use a push model, actively sending an HTTP POST request to a target URL when an event occurs in the source system, with significant advantages over polling in terms of latency and resource consumption.83% similarVerifiedWebhook is a 'reverse API' mechanism—traditional APIs use active polling, whereas Webhooks are event-driven, with the server proactively pushing new data.82% similarUnverifiedCallback is the standard pattern for asynchronous communication between web services, also known as Webhook; after receiving a callback request, the server typically needs to return an HTTP 200 status code within 30 seconds.71% similarUnverifiedStreaming responses push model tokens to the client incrementally via Server-Sent Events or WebSocket, which can improve perceived latency.70% similar
