Claude webhooks refer to integrating Claude into webhook-driven workflows where external events automatically trigger Claude to process, analyze, or respond to incoming data without manual intervention. When a customer submits a form, a GitHub issue is created, or a Slack message arrives, a webhook fires and Claude receives that event, processes the content, and routes a response back to the originating system. <\/p>\n\n\n\n
How Claude Webhooks Work<\/strong><\/h2>\n\n\n\n![\"How](\"https:\/\/www.guvi.in\/blog\/wp-content\/uploads\/2026\/08\/How-Claude-Webhooks-Work-1200x633.webp\" "\\"\\"")
<\/figure>\n\n\n\nA webhook<\/a> is an HTTP POST request that an external service sends to your server when a specific event occurs. Adding Claude to this flow creates a three-stage pipeline:<\/p>\n\n\n\nExternal event occurs<\/p>\n\n\n\n
\u2192 Webhook fires to your endpoint<\/p>\n\n\n\n
\u2192 Your server extracts relevant data<\/p>\n\n\n\n
\u2192 Claude processes the data with your prompt<\/p>\n\n\n\n
\u2192 Response routes to destination (Slack, database, email, API)<\/p>\n\n\n\n
This pattern runs without any human in the loop, making it suitable for high-volume time-sensitive workflows like support ticket classification, content moderation, and automated notifications.<\/p>\n\n\n\n

For local testing, install ngrok and run ngrok http 5000 to create a public URL that forwards to your local Flask server.<\/p>\n\n\n\n
