Send screenshots to web service

Send web page screenshots to any URL as you take them by clicking the extension's icon. Users can be authenticated in the backend service. If the web service URL is secured, e.g. Google Cloud function requiring authentication, an ID token with the user's Google identity, i.e. email address and Google ID, is can be added into requests as the Authorization header. You can specify your own Google OAuth client ID providing scopes other than email. The screenshots are sent as POST requests in multipart form data format. Besides the screenshot, posted data includes the captured web page URL and timestamp. Any custom parameters, e.g. Google Drive ID or Sheet ID can be added to request bodies. Screenshots can be optionally downloaded or copied to clipboard.
