Screenshots by Snapshot Site is Now Available on Zapier

The official Screenshots by Snapshot Site integration is now available on Zapier. It brings website capture, visual comparison, rendered-page analysis, and change detection into the same visual workflow builder teams already use for Slack, Google Sheets, Notion, email, storage, and thousands of other apps.

You no longer need to assemble the basic request with a generic webhook. Connect your Snapshot Site account, choose a trigger or action, map the URL from an earlier Zap step, and route the result into the next app.

Open Screenshots by Snapshot Site on Zapier or create a Snapshot Site account before building your first Zap.

What the Zapier integration includes

The integration exposes one trigger and three actions:

Zapier event	Type	What it does	Useful outputs
Website Changed	Trigger	Captures a page on Zapier's polling schedule and compares it with the previous capture	Change percentage, before image, after image, diff image
Capture Screenshot	Action	Renders a URL as an image, PDF, base64 payload, or HTML	Hosted asset URL, image data, rendered HTML, dimensions
Compare Pages	Action	Compares two URLs or an existing image with a live page	Pixel mismatch metrics and before, after, and diff assets
Analyze Page	Action	Captures and analyzes the rendered page	Summary, metadata, screenshot, readability and quality signals

These events map to the same core operations documented in the Screenshot API, Visual Diff API, and AI website analysis pages. Zapier provides the orchestration layer: another app supplies the URL, Snapshot Site processes the page, and a later step decides where the evidence or structured result should go.

1. Capture screenshots without an HTTP step

Use Capture Screenshot when a Zap already has a page URL and needs a visual asset. Common triggers include a new CMS item, a Google Sheets row, a form submission, a deployment event, or a scheduled review.

The action supports:

• hosted PNG, JPEG, WebP, or PDF output;
• base64 image output;
• rendered HTML;
• viewport width and height;
• full-page capture;
• a post-load delay;
• cookie-banner hiding;
• CSS selectors to hide;
• custom JavaScript before capture;
• language and country settings.

A straightforward workflow looks like this:

1. Trigger: a new campaign URL is added to a Google Sheet.
2. Action: Capture Screenshot renders the full landing page as PNG.
3. Action: Slack posts the page URL and hosted screenshot link to a review channel.
4. Action: Google Sheets stores that link beside the source URL.

If you previously built this flow with Webhooks by Zapier, the dedicated action removes the manual endpoint, header, and JSON configuration. The existing Slack and Google Sheets walkthrough remains useful for the routing pattern; replace its webhook step with Capture Screenshot.

2. Trigger a Zap when a website changes visually

Website Changed turns visual monitoring into a Zap trigger. On each check, the integration captures the configured URL, compares it with the previous capture, and emits an event when the mismatch reaches your minimum change percentage.

The first check behaves differently by design: it creates the initial baseline and does not trigger the downstream steps. The next check has two page states to compare.

Configure two separate controls carefully:

• Minimum Change (%) decides how much of the page must change before the Zap fires.
• Pixel Sensitivity controls how different individual pixel colors must be before they count as changed.

Start with a stable viewport and hide known volatile regions such as timestamps, rotating banners, or live counters. Otherwise, harmless motion can generate noisy alerts. The website monitoring guide explains how to choose representative pages and maintain useful baselines.

A practical monitoring Zap can be as small as:

1. Trigger: Website Changed monitors a pricing or product page.
2. Filter: continue only when the mismatch is above the team's review threshold.
3. Action: send the before, after, and diff links to Slack.
4. Action: append the timestamp and mismatch percentage to an audit sheet.

The trigger performs screenshot work whenever Zapier polls it, even when no change event is emitted. Choose the number of monitored URLs and your Snapshot Site plan with that recurring usage in mind. Review pricing before activating a large monitoring set.

3. Compare pages inside any Zap

Use Compare Pages when another event should initiate the check rather than the integration's polling trigger. For example, run a comparison after a deployment, when a QA ticket changes status, or when a content editor publishes a page.

Each side can be:

• a live URL with its own viewport and rendering options; or
• an existing image URL used as a fixed reference.

The action returns the mismatch percentage, mismatched pixel count, dimension check, and links to the before, after, and generated diff images. That makes the result useful for both machine routing and human review.

For deployment QA, a Zap could receive a release webhook, compare staging with production, and create a review task containing all three images. A mismatch is evidence that the pixels differ; it is not automatically evidence of a defect. Keep a reviewer in the loop when the decision affects a release. See the visual comparison workflow for guidance on separating detection from interpretation.

4. Analyze a rendered page and route the result

Analyze Page is useful when the workflow needs information about the rendered result rather than only an image. It can return:

• an AI-generated content summary;
• the page title and meta description;
• a screenshot link;
• a readability score;
• blank-page detection;
• CAPTCHA detection;
• HTTP status;
• whether a cached analysis was used.

This supports workflows such as sending new landing pages to an editorial review queue, logging metadata in a spreadsheet, or flagging pages that rendered blank before their screenshots reach an archive.

Treat the output as a structured review signal, not as proof that a page is correct or compliant. For an endpoint-level explanation of the response, read Turn Rendered Web Pages into Structured Data with the Analyze API.

How to connect Snapshot Site to Zapier

1. Visit the Screenshots by Snapshot Site integration page.
2. Start a Zap and select one of the Snapshot Site events.
3. Connect your Snapshot Site account using an API key from the console.
4. Map the page URL and configure the relevant capture, comparison, or analysis options.
5. Test the step with a representative public URL.
6. Map the returned links, metrics, or analysis fields into the next app.
7. Publish the Zap and inspect its first runs in Zap History.

Use a dedicated API key for automation when your account setup permits it, and do not paste secrets into URL fields, messages, spreadsheets, or other downstream content. The API authentication guide covers safer key handling.

Dedicated app or Webhooks by Zapier?

Use the dedicated app for the supported capture, compare, analyze, and visual-change workflows. Its fields and outputs are already mapped into Zapier, which makes the Zap easier to read and maintain.

Use Webhooks by Zapier only when you need a Snapshot Site endpoint or request option that the current integration does not expose. The REST API remains available, so a specialized workflow is not blocked by the app's current field set. Refer to the API documentation and screenshot API examples before constructing a custom call.

Start with one useful workflow

The best first Zap is a small, observable workflow with a clear owner: capture a newly submitted URL, monitor one important page, compare staging after a release, or analyze a newly published landing page. Confirm its output and recurring capture usage before expanding it across many pages.

Explore Screenshots by Snapshot Site on Zapier, then start with a free Snapshot Site account. If your automations run in a different environment, Snapshot Site also provides a verified n8n node, hosted MCP server, and direct REST API.
