A webhook is an automated message sent from one system to another when a specific event occurs. Instead of repeatedly checking whether a task is complete, the source system automatically notifies your server through an HTTP request once the event finishes. This allows software tools and APIs to communicate in real time and trigger follow up processes without manual intervention.
For marketing agencies, sales teams, and recruiters, webhooks enable fully automated data workflows that save time and reduce manual monitoring. When large data extraction or enrichment jobs run through APIs, a webhook can instantly notify your CRM, database, or automation platform that fresh leads are ready. This allows teams to move faster from data collection to outreach and lead qualification.
Real-World Example:
For example, a marketing agency running a Google Maps scraping job with Outscraper can configure a webhook so that once the scraping task finishes, the extracted business leads are automatically pushed into their CRM or email outreach tool for immediate campaign execution.
