Some reCAPTCHA v2 widgets have no submit button at all. Instead the page defines a callback function that runs automatically the moment the challenge is solved, and that callback is what actually submits the form or unlocks the next step. This is where a lot of automation quietly breaks: you get a perfectly valid token, paste it into the g-recaptcha-response field, and nothing happens, because nothing on the page is listening for it.
CapSkip is a reCAPTCHA v2 callback solver that handles both halves of the job. It solves the challenge locally on your own Windows machine or VPS at 90-100% accuracy and hands back a valid g-recaptcha-response token, and the browser extension fires the page callback for you so the form behaves exactly as it would for a real visitor. No remote human farm, no per-solve meter, and image challenges clear in about 0.1 seconds.
Where 2Captcha, Anti-Captcha and CapSolver bill per 1,000 solves, CapSkip is flat and unlimited: a $1 seven-day trial, then $10/month for unlimited solving with unlimited threads, plus a $99 one-time lifetime license. Use the no-code Chrome and Firefox extension, drive it from the Python, Node.js, PHP or .NET SDK, or point existing 2Captcha or Anti-Captcha client code at CapSkip's local API emulation and keep the code you already wrote.
No coding required. Run the CapSkip app and the browser extension connects automatically, then solves CAPTCHAs right in the page. Already using another service? Migrating is easy: CapSkip is a drop-in captcha solver that emulates 2Captcha, RuCaptcha, Anti-Captcha, CapMonster Cloud, CapSolver, DeathByCaptcha, SolveCaptcha and Captchas.io. Add your service to the hosts file in the CapSkip app and your existing code is routed to CapSkip and solved locally, with no changes.

Three ways to solve callback reCAPTCHA
from capskip import CapSkip
from selenium import webdriver
solver = CapSkip(host="127.0.0.1", port=8080)
driver = webdriver.Chrome()
driver.get("https://example.com/signup")
result = solver.recaptcha(
sitekey="6Lc_your-site-key",
url="https://example.com/signup",
)
token = result["code"]
# No submit button: set the token, then call the page callback with it.
driver.execute_script(
'document.getElementById("g-recaptcha-response").innerHTML = arguments[0];'
'myCallbackFunction(arguments[0]);',
token,
)Solve the challenge, drop the token into the response field, then run the callback the page normally fires on success.
No-code browser extension
Install the CapSkip extension and it detects the widget on any page and solves it for you, with nothing to script.
Official SDKs
Automate solving from your own code with the Python, Node.js, PHP and C# clients. A few lines returns a valid token.
Local HTTP API
Prefer raw HTTP? CapSkip exposes a local endpoint with 2Captcha and Anti-Captcha API emulation, so any HTTP client works.

We host live, interactive demo pages for every CAPTCHA type. Load the real widget, run CapSkip, and watch the token come back.

How to find and fire the reCAPTCHA callback
The callback is usually named in the widget's data-callback attribute, for example data-callback="myCallbackFunction". If the widget is built in JavaScript instead, look for the callback property passed to grecaptcha.render(). When neither is visible you can read it straight off the reCAPTCHA config object in the browser console at ___grecaptcha_cfg.clients[0].aa.l.callback, remembering that the aa.l path varies between pages and that a page with several widgets will have clients[1], clients[2] and so on to check. Once you know the name, solving is two steps: write the CapSkip token into the g-recaptcha-response field, then call the callback, passing the token as its argument if it expects one. The CapSkip browser extension does all of this for you in the page, so for no-code workflows there is nothing to look up at all.
What is a reCAPTCHA callback?
It is a JavaScript function the page registers with the widget, which reCAPTCHA runs automatically once the challenge is solved. On forms with no submit button, that callback is what actually submits the data or unlocks the next step.
Why does my token not work when there is no submit button?
Because setting g-recaptcha-response only stores the answer; it does not tell the page that verification succeeded. The page is waiting on its callback, so you have to run the callback yourself after injecting the token.
How do I find the reCAPTCHA callback function?
Check the data-callback attribute on the widget first, then the callback property passed to grecaptcha.render(). Failing both, inspect ___grecaptcha_cfg.clients[0].aa.l.callback in the browser console, and check clients[1] and beyond if the page has more than one widget.
Do I need to pass the token to the callback?
Often yes. Many callbacks accept the solved token as their only argument, so calling myCallbackFunction(token) is the safe default. Some take no argument at all, in which case calling it bare is enough.
Does the CapSkip extension handle callbacks automatically?
Yes. Run the CapSkip app and the free Chrome or Firefox extension detects the widget, solves it, injects the token and fires the callback in the page, so no-code workflows need nothing looked up or scripted.
Can I solve callback reCAPTCHA in Selenium or Python?
Yes. Get a token from the CapSkip Python SDK, then use driver.execute_script to set g-recaptcha-response and invoke the callback. The Node.js, PHP and .NET SDKs work the same way with their own browser drivers.
Does invisible reCAPTCHA use a callback too?
Usually, yes. Invisible reCAPTCHA has no checkbox and normally runs a callback once the challenge completes, so the same technique applies. See the invisible reCAPTCHA solver page for the details specific to that mode.
How much does solving callback reCAPTCHA cost?
CapSkip is flat unlimited: $1 for a 7-day trial, then $10/month Bronze, $17 Silver, $20 Gold, plus a $99 one-time lifetime license, with no per-1,000-solve charges however many widgets you clear.
