What does the payload look like?

Every change-detected event sends a POST with this JSON body shape: { "event": "competitor_change", "timestamp": "2026-05-13T17:29:45.812Z", "competitor": { "id": "68a1c4d2f3...", "name": "Stripe", "domain": "stripe.com" }, "change": { "id": "6a04f7232751f380...", "type": "pricing", "importance": 9, "page": { "title": "Pricing", "path": "/pricing", "url": "https://stripe.com/pricing" }, "summary": "Standard plan rate increased from 2.9% + 30c to 3.0% + 30c.", "detected_at": "2026-05-13T17:29:45.812Z", "view_url": "https://app.spyglow.com/changes/6a04f7232751f380..." } } The top-level "event" field is always "competitor_change" for change detections. Slack-format payloads and Microsoft Teams-format payloads have different shapes; this is the generic format used when you point a webhook at your own endpoint.

Do you retry on failure?

No. Each change is sent once, and a failed delivery is not retried.

Can I have multiple webhooks?

Yes. Add as many endpoints as you need, each with its own URL and filter rules. A common pattern is one webhook for high-impact changes routed to PagerDuty and another for everything routed to a data warehouse.

Can I filter by change type?

Yes. Per-endpoint filters let you scope a webhook to pricing changes only, or feature launches only, or any combination. The same importance threshold from your account also applies, so low-impact noise stays out.

Is this rate-limited?

Realistically no. Even on Teams plans with 25 competitors and 3-hourly scans, most accounts see fewer than a hundred high-impact changes a month. We will not throttle your endpoint unless something is producing thousands of changes a day, in which case we will reach out first.

Does this work on the Free plan?

No, webhooks are included on Pro, Growth, and Teams. Free users get email and in-app alerts.

Pipe competitor signals into your own stack

Webhook alerts to any endpoint.

Yes, SpyGlow has a native webhook integration. Receive JSON payloads at your endpoint the moment a tracked change happens. Pipe SpyGlow intelligence into your data warehouse, your CRM, your Discord server, or anything else that speaks HTTP.

The intelligence layer

A polling job tells you wakes up every hour and asks "anything new?". SpyGlow gives you a POST the moment a change is classified, no polling required.

What you get

Everything packed into one workspace.

Per-event filtering

Configure which change types and impact thresholds trigger your webhook. A finance team can get only pricing changes; a product team can get only feature launches.
