Webhook
A Webhook is an automated, real-time HTTP notification that a CRM sends to an external system when a defined event occurs, such as a deal closing, a form being submitted, a contact record being created, or a support case being escalated. Unlike polling-based integrations that check for updates at scheduled intervals, webhooks push data to the receiving system immediately when the triggering event happens, enabling real-time data flow between the CRM and connected platforms. For enterprise integration architectures, webhooks are the mechanism that makes event-driven automation possible: when a deal closes in the CRM, a webhook can simultaneously trigger contract generation in a DocSign system, order creation in the ERP, and onboarding task creation in the project management tool.
A webhook is an automated message a system sends to another system when an event happens, pushing data in real time rather than waiting to be asked. Where an API call is a request you make, a webhook is a notification you receive. In CRM, webhooks trigger downstream actions, such as notifying another system the moment a deal closes, enabling real-time, event-driven integration.
