Recaptcha

Frequently Asked Questions

• How to distinguish between v2 and v3?

  • Unlike other platforms, we only differentiate between the regular version and the enterprise version. The differences between v2 and v3 are:

    • v3 ends at the reload interface, and its size parameter is typically invisible (please refer to the web interface). It also requires the action parameter. Open f12, search for grecaptcha.execute and find the action value in the argument object of this function. Input it into the action parameter.

    • After the v2 reload interface, you need to request the userverify interface. Its size is usually normal (please refer to the web interface), and there’s no need to pass the action parameter.

    • The regular and enterprise versions have identical interface parameters. The only difference is the request route.

• How to differentiate between the Regular Version and the Enterprise Version?

  • Regular Version: anchor interface route: /recaptcha/api2/anchor

  • Enterprise Version: anchor interface route: /recaptcha/enterprise/anchor

• For enterprise versions with an s value (like steam), why doesn’t the token obtained from the interface work?

  • It’s related to the quality of the proxy you’re using. Please try using your local IP or switch the proxy. If it still doesn’t work, contact customer service.

Why Choose Us

• Universality: Currently known websites can pass the verification (including enterprise versions with an s value that other platforms can’t handle, like steam). The interface is unified for v2 and v3.

• Ultimate speed: Most interfaces on the market are asynchronous. You need to first create a task, then obtain the task ID, and constantly poll to get the verification result. Sometimes, this can take up to 1 minute, which is unacceptable. Our interface uses pure algorithm calculations, protocol submissions, and provides synchronous returns. The average return for v3 invisible and v2 is 1s, while v2 other image-click types are fastest at 2s and will not exceed 10s (this also depends on the speed of the proxy).

• High Availability: The v3 score is high. For most high-risk control sites (such as various enterprise versions), the token value produced by our interface can successfully pass risk control and obtain target data.

• Stability: Timely updates (no more than two hours) to better support your business.

Parameter Name	Description	Required
x-api-key	User key, obtained from the homepage	Yes
Content-Type	application/json	Yes

POST Data (JSON):

Parameter Name	Type	Description	Required
sitekey	String	Google verification docking key (k value of the anchor/reload interface)	Yes
referer	String	🚨🚨🚨 Trigger page address. ✅Please copy the full address displayed on the browser✅. Do not alter it, and definitely don't search for it in developer tools❌.	Yes
size	String	Validation type (e.g. invisible/normal, usually there are only these two choices, specifically check the size value of the anchor interface, they must match).	Yes
title	String	Trigger the page's title (open the console with F12, type in document.title).	Yes
action	String	For the verification code trigger page, search grecaptcha.execute(client, {action: action}), where the action value is only required for v3.	No
ubd	Boolean	Check whether the verification route is the special 'ubd' type. The default is false.	No
s	String	Steam project's 's' value. It's generally not required to be filled in. Currently, only the Steam project needs it to be filled in.	No
sa	String	some website anchor interface route has 'sa'. It's generally not required to be filled in. Currently. only some Enterprise Version needs it to be filled in.	No
version	universal | enterprise | steam		Default is universal

Parameter Lookup Steps

1. Get parameters Inside the Developer Tools.

• Search for the anchor interface and obtain the k, size, and hl parameters. The k value is the sitekey. Fill in the corresponding field accordingly. If hl is zh-CN, you can leave it blank, as shown in the picture below:

  • 

• Switch to the console, type in document.title, and fill the output value into the title field.

  • 

• If, according to the aforementioned v2/v3 differentiation method, you determine that the verification is v3, you will also need to find and fill in the action parameter. The method to find it is as follows:

  • Method 1: Press F12, search for .execute( in the standard version or .enterprise.execute( for the enterprise version. Look for the action parameter in the code, as shown in the picture below. If you can’t find it, please use Method 2.

    • 

  • Method 2: Press F12, enter debug(grecaptcha.execute) for the standard version or debug(grecaptcha.enterprise.execute) for the enterprise version. Click on login or complete the verification, and wait for the breakpoint to trigger. Copy the value of action from the Scope, as shown in the picture below:

    • 

    • 

• Check if the verification route is of the ubd type (currently only seen in the enterprise version of one website). If it is ubd, please fill in the ubd parameter as true. Otherwise, fill in false or leave it blank:
