Same options as for a URL
-------------------------

 Send `html` in place of `url`. Every other option works the same way, so you can choose the output and the size.

 ParameterWhat it does  `html`The markup to render, up to 2,000,000 characters. Send either `html` or `url`. `file_type` `png`, `jpg`, `webp` or `pdf`. `window_width` `window_height`Size of the browser window in pixels. Use 1200 × 630 for social cards. `device_scale_factor`Pixel density. Use 2 for sharp images. `selector`Capture one element, such as `.card`, instead of the whole window. `paper_format`For PDFs: A4, Letter and more. See the [PDF page](https://3.screeenly.com/features/pdf). `delay`Wait this many milliseconds before the capture, for example while a chart animates.  

Code examples
-------------

 curl 

```
curl --request POST \
  --url https://3.screeenly.com/api/v1/shots \
  --header "authorization: Bearer $token" \
  --data-urlencode html='Hello' \
  --data window_width=1200 \
  --data window_height=630
```

 php 

```
$imageUrl = Http::withToken($token)
    ->asForm()
    ->post('https://3.screeenly.com/api/v1/shots', [
        'html' => view('social-card', ['post' => $post])->render(),
        'window_width' => 1200,
        'window_height' => 630,
    ])
    ->json('data.shot_url');
```

Images, fonts and CSS
---------------------

 The HTML has no address of its own, so relative paths such as `/logo.png` do not resolve. Put your CSS in a `` tag, and use full URLs for images and fonts. Everything you reference has to be publicly reachable. Small images can be inlined as `data:` URIs.

What you can build with it
--------------------------

Social and open graph images

One template, a fresh image for every blog post or product.

Invoices and receipts

Render the page you already email, as a PDF with the right paper size.

Charts and reports

Turn a chart library's output into an image for emails and chat.

Email previews

See how a template looks in a browser before you send it.

screeenly is not a web scraper

screeenly loads pages the way a regular browser does. It cannot get past bot protection such as Cloudflare challenges, CAPTCHAs or other checks that decide a visitor is not human, and it does not try to. Use it on your own pages and on pages you are allowed to load.

Questions
---------

   Does JavaScript run in my HTML?  Yes. Scripts run in Chrome like on any page. Use `delay` if you need to wait for a chart or animation.

   Do I need a public URL for my template?  No. The HTML travels in the request. Only the things it references, such as images and fonts, have to be publicly reachable.
