Have you ever wondering if you could quickly take a screenshot of a webpage using just a single request?

RenderForm API allows you to not only create images using templates and API but also take a screenshots using REST API.

There are plenty use cases of that:
- Post it on social media
- Make a list of websites
- Detect branding based on colors
- Test or health-check your webpage
- Read texts from screen


## How to take a screenshot with API?

Generate your API key in RenderForm by signing up to the system. Get the API key from your account section and then you can make a request like below.

```shell
curl
    --location
    --request POST 'https://api.renderform.io/api/v1/screenshots' \
    --header 'X-API-KEY: <API_KEY>' \
    --header 'Content-Type: application/json' \
    --data-raw '{
        "url": "https://renderform.io"
        "width": 1366,
        "height": 768,
    }'
```

RenderForm API will respond after a couple of seconds with link where you can download the screenshot. Example successful response is shown below.

```json
{
  "requestId": "ed39c85ac41f4c54b95e4caaad4ebff8",
  "href": "https://cdn.renderform.io/.../image.png",
  "request": {
    "width": 1366,
    "height": 768,
    "url": "https://renderform.io"
  }
}
```

## Screenshot API parameters

As you seen above we passed `url` of the website, `width` and `height` of the screenshot. These parameters are required but you can add more options:

- `url` (required) - website URL of which RenderForm should take a screenshot
- `height` (required) - screenshot height
- `width` (required) - screenshot width,
- `expires` (optional) - add expiration time in seconds for the image, available values from `1` to `604800`
- `waitTime` (optional) - add wait time in milliseconds before taking a screenshot, available values from `500` to `5000`
- `webhookUrl` (optional) - send response to the given webhookUrl as POST request

## Does it integrate with other tools?

Yes! RenderForm is integrated with Zapier and Make.com (Integromat). Soon we will add more integrations like n8n.io. Please also notice that
every request supports a webhook. Taking a screenshot takes time because it's very resource demanding and complex process for servers.
You can pass a URL in `webhookUrl` field, thanks to that RenderForm API will accept your request and immediately
 return you a response. Once RenderForm finish processing your request a new request will be sent to the given URL in `webhookUrl`.

## Can I set an expiration date?

Yes, you can set expiration date on every screenshot from 1 second up to 7 days. Add a field `expires` and put there
an expiration value in seconds. RenderForm API return you a link in `href` field which will be valid for requested period of time.
