Webhook
A webhook is an HTTP callback mechanism where a system sends an automated HTTP request to a specified URL whenever a defined event occurs, enabling real-time notification and integration between services without polling.
理解する Webhook
Webhooks are often called 'reverse APIs.' Instead of your application periodically asking a service 'has anything changed?' (polling), the service proactively calls your application when something changes. This event-driven model is more efficient and more real-time. A webhook is set up by providing a URL to the service you want to receive events from. When the event occurs (a new email arrives, a payment succeeds, a task is completed, a form is submitted), the service sends an HTTP POST request to your URL with a payload describing the event. Your server processes the payload and takes action. Webhooks power most modern integrations. When a GitHub PR is merged, GitHub sends a webhook to your CI system. When a Stripe payment succeeds, Stripe webhooks trigger order fulfillment. When a Calendly event is booked, Calendly webhooks can trigger CRM updates. Webhook reliability requires handling failure cases: retries when the receiving server is down, signature verification to confirm the webhook is authentic, idempotency to handle duplicate deliveries, and queue-based processing to handle high event volumes.
GAIAの活用方法 Webhook
GAIA uses webhooks to receive real-time events from connected tools. When a new email arrives in Gmail, a task is updated in Linear, or a Calendly event is booked, webhooks notify GAIA immediately so it can act — creating a task, sending a notification, or triggering a workflow — without the latency or overhead of periodic polling.
