Webhooks are an efficient method of real-time data sharing across applications, triggered by specific events in a source application that send POST requests to designated endpoints in a destination application. Unlike traditional APIs, which typically require regular polling to exchange data, webhooks operate unidirectionally and provide immediate updates, making them ideal for scenarios where time-sensitive responses are crucial. Common use cases include notifying sales teams of new leads, updating ecommerce inventories post-purchase, creating tickets for client-reported issues, and facilitating timely employee gift deliveries. Setting up webhooks involves identifying the relevant event, configuring the source application, testing the setup, and documenting the process for organizational clarity. Merge's Unified API platform offers versatile webhook integrations, allowing users to send and receive data payloads across a wide array of applications, enhancing integration efficiency and effectiveness.
