Errors

There is a detailed guide on how to handle the ScreenshotOne API errors.

The request might return an error due to an internal error, invalid options or when the limit is reached. Our screenshot API follows the HTTP status code semantic and returns JSON in case of an error:

GET https://api.screenshotone.com/?[options]

Content-Type: application/json
{
    "is_successful": false,
    "error_code": "an_error_code",
    "error_message": "An error message",
    "documentation_url": "..."
}

The API will always return a human-readable error message, error code as a string key, and suitable HTTP status code.

Codes with explanations

Error Code	HTTP Status	Explanation
access_key_required	400	The “access_key” parameter is required. Please, check out the access page to get the access key.
access_key_invalid	400	The “access_key” parameter is given, but it is not correct. Please, check out the access page to check the access key.
signature_is_required	400	The “signature” parameter is required. Because signing requests is required in the access page. Make sure you use the correct signing algorithm.
signature_is_not_valid	400	You provided the “signature” parameter, but it is not valid. Make sure you use the correct signing algorithm.
screenshots_limit_reached	400	The usage quota has been exceeded. Please, either upgrade to a plan with more quota or change the maximum allowed limit (if possible) in the ScreenshotOne dashboard. If it is a mistake, please, reach out at `support@screenshotone.com.`
concurrency_limit_reached	400	You reached the request concurrency limit, retry after a while. Or feel free to upgrade you current plan.
request_not_valid	400	The request parameters are not valid. You can look at the `error_details` response field to get the details.
selector_not_found	400	If selector is specified and `error_on_selector_not_found=true`, the error will be returned if the element by selector is not visible or it took more than `timeout` seconds to render it, but not more than 30 seconds.
name_not_resolved	400	Usually, the error happens when the domain name of the requested URL is not resolved. If you are trying to take a screenshot of the new site, please, wait a bit until the DNS records are refreshed.
network_error	500	The error happens when the API can’t connect to the provided URL. It might mean that the site blocks the API or is temporarily unavailable. Generally, you can safely retry to take a screenshot.
invalid_storage_configuration	400	If you haven’t created the bucket in the `us-east-1` AWS region, please, specify your bucket region through an endpoint in a format like `https://s3.<your-region>.amazonaws.com`.

host_returned_error	500	If the host doesn’t respond successfully within the range of 200-299 status codes, the API won’t take a screenshot. You can force the API to take a screenshot of the error page by specifying ignore_host_errors=true. You can get the returned status code from the site by reading the `returned_status_code` field.
timeout_error	500	The screenshot couldn’t be taken within the specified timeout. Either the site doesn’t respond quickly, or rendering takes longer than expected. Play with the `timeout` or the `navigation_timeout` options or reach the support for the investigation.
