Overview

Blitapp is a screenshot-as-a-service API that lets you capture full-page or viewport screenshots of any web page on a schedule, then automatically sync them to cloud storage like Dropbox or Google Drive. An API key is required and available after account registration. It is useful for monitoring web page changes, generating visual reports, or archiving web content over time.

💡

Beginner Tip

After signing up, get your API key from the Blitapp dashboard. Start with a simple screenshot request by specifying a URL and your desired screen size before setting up scheduled captures.

Common Errors & Troubleshooting

401 Unauthorized / Invalid API key API key is missing or incorrect in the request.
✓ Include your API key in the request as specified in the Blitapp docs (typically as a query parameter or header), and verify it matches the key in your account dashboard.
Screenshot timeout The target web page takes too long to fully load before the screenshot is captured.
✓ Increase the delay parameter in your request to give the page more time to render JavaScript before capturing.
Quota exceeded You have used all the screenshots available in your current plan.
✓ Upgrade your Blitapp plan or wait for your quota to reset at the start of the next billing period.
