# 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/csharp)

## 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 C# request (HttpClient)

This is the complete C# request for this example using HttpClient. It includes the HTML, CSS, authentication setup, API options, and response handling needed to reproduce the output.

```csharp
using System.Net.Http.Headers;
using System.Net.Http.Json;
using System.Collections.Generic;
using System.Text;
using System.Text.Json.Nodes;

var apiId = Environment.GetEnvironmentVariable("HCTI_API_ID")!;
var apiKey = Environment.GetEnvironmentVariable("HCTI_API_KEY")!;
using var client = new HttpClient();
var credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes($"{apiId}:{apiKey}"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);

var request = new
{
    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>
           
           """,
    ms_delay = 2500,
    render_when_ready = false,
    selector = ".fb-post",
};

using var response = await client.PostAsJsonAsync("https://hcti.io/v1/image", request);
response.EnsureSuccessStatusCode();
var result = await response.Content.ReadFromJsonAsync<JsonObject>();
var imageUrl = result?["url"]?.GetValue<string>();
if (imageUrl is not null)
{
    Console.WriteLine(imageUrl);
}

```

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.
