Best Way to Receive Updates from APIs Without Webhooks (Without Building Polling Systems)
Blog post from Unified.to
APIs lacking native webhook support often rely on incremental polling, which involves building and maintaining a complex synchronization system to manage updates. This method, though common, requires significant infrastructure to handle scheduling, cursor storage, retry logic, and rate-limit coordination, frequently leading teams to create a system that converts polling into an event-driven model. Unified offers a more scalable solution by centralizing change detection and event delivery, effectively transforming pull-based APIs into event-driven systems without needing additional polling infrastructure in applications. Unified achieves this by utilizing native webhooks when available and employing timestamps or cursors to detect and deliver changes as events when webhooks aren't supported, allowing applications to remain event-driven while offloading the complexities of polling infrastructure.
