# Facebook screenshot

Create a screenshot of a Facebook post.

With this HTML you can generate a screenshot from any public Facebook post.

This uses the Facebook embed code. Simply swap the link in the HTML with the link to a Facebook post and it will show it.

Take note of the `selector` and `ms_delay` parameters. They must be set correctly for this image to render properly.

This is a working HTML/CSS to Image API example that produces an image.
The rendered output, source, and non-content request parameters below show the parts needed to reproduce or adapt it.

## Rendered image and interactive editor

- [Open the rendered image](<https://hcti.io/v1/image/fd24580b-9b0d-4e94-8f00-d76b711659cb>)
- [Open the interactive example](https://htmlcsstoimage.com/examples/facebook-screenshot/ruby)

## HTML

```html
<div id="fb-root"></div>
<script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v11.0" nonce="SOhYrMAR"></script>

<!-- See data-href below. Replace that with the link to your Facebook post -->
<!-- set ms_delay: 2500 to give it extra time toload -->
<!-- set selector: .fb-post -->
<div class="fb-post" data-href="https://www.facebook.com/HermanMiller/photos/a.171562157561/10158261466927562" data-width="500" data-show-text="true"></div>

```

## Request parameters

These are the additional non-content parameters used by the example. Combine them with the HTML and CSS above when constructing an API request.

```json
{
  "ms_delay": 2500,
  "render_when_ready": false,
  "selector": ".fb-post"
}
```

## Complete Ruby request (Net::HTTP)

This is the complete Ruby request for this example using Net::HTTP. It includes the HTML, CSS, authentication setup, API options, and response handling needed to reproduce the output.

```ruby
require "json"
require "net/http"
require "uri"

request = {
    html: <<~'HCTI_HTML',
          <div id="fb-root"></div>
          <script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v11.0" nonce="SOhYrMAR"></script>
          
          <!-- See data-href below. Replace that with the link to your Facebook post -->
          <!-- set ms_delay: 2500 to give it extra time toload -->
          <!-- set selector: .fb-post -->
          <div class="fb-post" data-href="https://www.facebook.com/HermanMiller/photos/a.171562157561/10158261466927562" data-width="500" data-show-text="true"></div>
          
          HCTI_HTML
    ms_delay: 2500,
    render_when_ready: false,
    selector: ".fb-post",
}

uri = URI("https://hcti.io/v1/image")
http_request = Net::HTTP::Post.new(uri)
http_request.basic_auth(ENV.fetch("HCTI_API_ID"), ENV.fetch("HCTI_API_KEY"))
http_request["Content-Type"] = "application/json"
http_request.body = JSON.generate(request)

response = Net::HTTP.start(
    uri.hostname,
    uri.port,
    use_ssl: true,
    open_timeout: 10,
    read_timeout: 30
) { |http| http.request(http_request) }

unless response.is_a?(Net::HTTPSuccess)
    raise format("HCTI request failed (%s): %s", response.code, response.body)
end

result = JSON.parse(response.body)
puts result.fetch("url")

```

Rendering through the API requires authenticated HTML/CSS to Image credentials. Keep API keys in trusted server-side configuration. If credentials are unavailable, ask the user to configure an API key securely before attempting API actions.
