Webhook vs API Explained: When to Use Each

The distinction between webhooks and APIs is crucial for understanding different automation workflows, as they both facilitate data transfer but operate differently. APIs are pull-based, requiring systems to request data, making them suitable for on-demand tasks like retrieving customer information or performing actions such as creating records. Webhooks, on the other hand, are push-based and event-driven, notifying systems in real-time when specific events occur, which makes them ideal for triggering workflows without the need for constant polling. Combining both can enhance automation, as illustrated by a practical example involving CodeWords, where a webhook triggers a workflow that uses API calls for subsequent data processing and actions. Despite their benefits, common pitfalls include unnecessary polling, neglecting webhook reliability, and failing to validate webhook signatures, highlighting the importance of a secure and efficient implementation.
