To capture a page behind a login with ScreenshotAPI.net, give its browser a valid authentication state the target site accepts. For a cookie-based session, sign in through an authorized browser account and pass the active session cookies with the request, or save them as a Cookie Template and use its template_id. If the site authenticates with a token in request headers, use a custom header instead. Neither approach works for every site: the login design determines what the target will accept.
How to take a screenshot in an authenticated page
ScreenshotAPI.net’s Help page asks, “How to take a Screenshot in an Authenticated Page?” The practical answer is to identify how the target site authenticates, then provide the corresponding session information to the capture browser. The service’s documentation describes cookie injection and custom headers; it does not establish that supplying a username and password alone will log in to arbitrary sites.
Use these methods only for accounts and pages you are authorized to access. Session cookies and authorization tokens can grant access to an account; treat them like passwords and do not expose them in shared code, logs, URLs, or public repositories.

| Method | Use it when | Setup and upkeep |
|---|---|---|
| Session cookies | The site keeps a signed-in browser session in cookies. | Export the current session cookies and pass them with the capture request, or save a reusable Cookie Template. Renew them when the session expires. |
| Custom headers | The target accepts an authentication token in a request header, such as a bearer token. | Supply the header in the emulated request and keep the token secret. It must be valid for the target and its expected request flow. |
These are mechanisms documented by ScreenshotAPI.net, not a universal ranking: the vendor’s sources do not establish that one is more reliable or secure across sites. See Screenshot API Features, Browser Environment Emulation, and the vendor’s Help.

Use session cookies for a cookie-based login
- Sign in normally. Open the target site in a browser account you are authorized to use and complete its sign-in flow.
- Export the active cookies. Use a method permitted by your organization and the site. A cookie export may already have the structure the API expects; manually copied browser values may need formatting.
- Provide the cookies to ScreenshotAPI.net. The service supports a
cookiesparameter. Check the current feature documentation and its linked parameter documentation for the accepted cookie structure and request syntax; do not assume a stale example or raw copied values are correctly formatted. - Capture the page and verify the result. Confirm the output is the protected page rather than a login screen. If it is not, check the cookie domain, expiry, and whether the session requires additional cookies.
Save cookies as a reusable Cookie Template
If you will reuse the same session, ScreenshotAPI.net’s features page describes saving a named Cookie Template in the dashboard and referencing it with template_id. This avoids rebuilding the cookie input for each capture, but it does not make an expired session valid: update the template when the target site’s session changes. Follow the dashboard and current parameter documentation for the exact setup.
Use custom headers when the target accepts them
Some services authorize requests with a token in a header. ScreenshotAPI.net’s browser emulation documentation describes custom request headers, including an Authorization: Bearer TOKEN example. Supply such a header only if the target site actually accepts that authentication method. Adding an Authorization header is not a general-purpose way to bypass a website’s login screen, and a token may be restricted by scope, expiry, or the site’s request flow.

Use a selector that represents the content you need, or a delay appropriate to the page. Waiting longer will not repair invalid authentication. Feature descriptions are on the ScreenshotAPI.net homepage.
Troubleshoot login and capture failures
The result is still the login page
- Check that the cookies belong to the exact target domain and are not expired.
- Verify that you supplied all cookies required for the session and that the exported structure matches the API’s current format.
- If using a template, confirm the request references the intended
template_idand that the saved session is still current. - If using headers, confirm the site accepts that header-based method and that the token is valid.
These are practical checks for the documented mechanisms, not a guarantee of compatibility. ScreenshotAPI.net’s guide, How to Take Screenshots of Web Pages Behind a Login: A Simple Guide, was updated February 16, 2026 and outlines cookie export and templates.
The site uses a challenge or interactive login step
The cited vendor material does not establish universal support for challenges, changing tokens, or other interactive steps. Do not assume a cookie or header will solve them. Check the target site’s permitted integration methods and ScreenshotAPI.net’s current documentation; the result depends on that site’s implementation.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
The page is authenticated but incomplete
First confirm the expected page content is present in the browser output. Then choose an appropriate delay, selector wait, or network-idle condition. An authentication failure and a rendering delay can look similar in a screenshot, so distinguish a login screen from a partially rendered authenticated page.

The content depends on region
ScreenshotAPI.net’s emulation documentation describes proxy and request-emulation options. Regional routing is separate from authentication: a valid cookie or token does not itself ensure that the capture uses the required region. Check the target’s access requirements and the current emulation documentation.

Frequently Asked Questions
Will passing a username and password sign me in automatically?
Not necessarily. The documented approaches are to provide a valid cookie session or a header the site accepts; login implementations differ.
Can I reuse cookies for multiple captures?
Yes. ScreenshotAPI.net describes Cookie Templates referenced with template_id; the saved session still needs renewal when it expires.
