Which Unified API Solutions Have Virtual Webhooks or Scheduled Polling to Access Data?

Unified API solutions address the challenge of synchronizing with third-party APIs that lack native webhooks through two main approaches: virtual webhooks and scheduled polling. Virtual webhooks simulate the behavior of native webhooks by regularly polling source APIs, detecting changes, and pushing events to applications without storing customer data. Scheduled polling involves fetching data at fixed intervals, and may require either pushing events to users or allowing them to pull updated records. Different providers implement these methods with varying intervals and data architectures, impacting data freshness, storage, and delivery models. For example, Unified.to offers virtual webhooks with configurable polling intervals and no data storage, while Apideck and Merge.dev use scheduled polling with different storage strategies. Understanding these differences is crucial for product teams focusing on real-time features, as they influence not only the synchronization frequency but also the complexity, compliance, and security of data handling.
