# Glean Webhooks & Events ## Overview Glean uses an event-driven indexing model where source system webhooks trigger incremental updates to the Glean Indexing API. Instead of emitting its own webhooks, Glean receives document changes from platforms like GitHub, Confluence, and Notion. You can also monitor internal Glean events such as document indexing completion, permission changes, connector sync status, and search anomalies through the admin API. ## Webhook Registration ```typescript // Register a source system webhook that pushes to Glean Indexing API const response = await fetch("https://yourapp.com/admin/webhooks", { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ url: "https://yourapp.com/webhooks/glean-indexer", events: ["document.indexed", "permission.changed", "connector.synced", "search.anomaly"], secret: process.env.GLEAN_WEBHOOK_SECRET, }), }); ``` ## Signature Verification ```typescript import crypto from "crypto"; import { Request, Response, NextFunction } from "express"; function verifyGleanSignature(req: Request, res: Response, next: NextFunction) { const signature = req.headers["x-glean-signature"] as string; const expected = crypto.createHmac("sha256", process.env.GLEAN_WEBHOOK_SECRET!) .update(req.body).digest("hex"); if (!crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(expected))) { return res.status(401).json({ error: "Invalid signature" }); } next(); } ``` ## E...
