How to take a screenshot of a website in Zapier (Webhooks)

If you automate with Zapier and need a screenshot of a web page inside a Zap (a link thumbnail, a preview), it can be done. There's no native step to "capture a website", but with Webhooks by Zapier and the Cofferdock API you can set up the call without coding.

One honest thing to know before you start: Zapier handles images returned by APIs less smoothly than tools like n8n or Make. It works, but if your flow will move lots of screenshots or you need to chain them easily, n8n or Make will make your life easier. Still, for simple cases Zapier gets the job done. Here's the straight story.

What you'll get

You send the URL of a public website and the API returns the screenshot. In Zapier the usual pattern is to receive it and pass it to the next step (for example, upload it to Google Drive or attach it to an email).

What you need

A Cofferdock account. The free plan gives 50 uses a month with no card.
Your API key, which you create in your dashboard with "+ Create key" (shown once, save it).
Webhooks by Zapier, which is a feature of Zapier's paid plans.

Step by step with Webhooks by Zapier

In your Zap, add an action step and choose Webhooks by Zapier.
In Event, choose Custom Request.
Set up the request:

- Method: POST - URL: https://api.cofferdock.com/screenshot?width=1280&height=800 - Data Pass-Through?: No - Data: paste the URL of the site you want to capture (or bring it in from a previous step). - Headers: add x-api-key with your key, and Content-Type with the value text/plain.

Test the step and check what it returns.

The tricky part: the image coming back

This is where Zapier is more limited. The API can return the screenshot in two ways, and in Zapier it pays to choose well:

As a binary file (the default). Zapier sometimes exposes that file to the next step, but it doesn't always handle it cleanly.
As base64 text, which is easier to work with in Zapier. For that, instead of text/plain, send the request in JSON mode: set the Content-Type header to application/json and put an object in Data like {"url":"https://cofferdock.com","width":1280,"height":800}. The response carries the image in the image field as base64, which you can use in steps that accept base64.

If your destination app (Google Drive, for example) doesn't handle either one well, the easiest route is to do this part in n8n or Make, which hand back the file ready for the next step with no fuss.

Options you can tweak

Add them to the URL, after the ?, separated by &:

Option	Default	What it does
`width`	`1280`	Viewport width in pixels.
`height`	`800`	Viewport height in pixels.
`full_page`	`false`	Set it to `true` to capture the full page, not just the visible part.
`format`	`png`	Format: `png` or `jpeg`.
`output`	per mode	`image` forces the binary; `json` forces base64.

Prefer to see it in code?

The same call with curl, in case you want to try it before building it in Zapier:

curl -X POST "https://api.cofferdock.com/screenshot?width=1280&height=800" \
  -H "x-api-key: YOUR_KEY" \
  -H "Content-Type: text/plain" \
  --data-binary "https://cofferdock.com" \
  -o screenshot.png

How much does it cost?

Each screenshot spends 1 credit from your Cofferdock plan. All tools share the same pool of credits.

FAQ

Does Zapier have a native step to capture a website? No. You do it with Webhooks by Zapier (a paid feature) calling the Cofferdock API.

Why do you recommend n8n or Make for images? Because they hand back the image file ready for the next step, while in Zapier handling the returned file is more awkward.

Can I get the screenshot as base64? Yes. Send the request in JSON mode (Content-Type: application/json) and the response will carry the image in the image field as base64.
