API Version 3

We have a new and exciting release of the Screenshot API with many improvements, a brand new rendering engine and new features.

In order to switch to the new version you will need to change your API url from v2 to v3, as in https://restpack.io/api/screenshot/v3/capture.

It is mostly backwards compatible so you should be able to switch without any issues.

Faster Rendering: The version 3 of screenshot API is around twice as fast compared to v2.

Better Engine: Our rendering engine now uses the latest Chromium releases, providing better standards compliance.

New Wait Modes: In previous versions the API would wait for the window load event before rendering the screenshot. Now you have an option to wait for network to become idle using wait=network parameter to ensure pages load completely even with a lot of async resources.

Shutter: If you need to control the precise moment of capture, you can use shutter=<css selector> parameter to wait for a DOM element before capture. Combined with js injection, you can control the render time as you wish.

Media Emulation: Now it’s possible to emulate print css media using emulate_media=print parameter if you wish to capture pages in printing mode.

Better Retina: While the previous version had a retina mode, it came with some caveats regarding to retina image loading, now retina=true parameter creates true retina images with device scale factor of 2.

More Metadata: Using the json=true parameter now returns details regarding to the page and server response, as well as the CDN url of the captured image as it always did.

Better Error Reporting: The new API is more transparent regarding to the errors caused by the remote server or on our end. You can work around errors more easily due to this granular error information.

Ability To Capture Error Pages: The previous API would only capture pages with status code of 200-299, now you can override this behavior using allow_failed=true parameter.
