BinanceTaskProxyless

websiteURL<string>required

The address of the main page where the captcha is solved.

websiteKey<string>required

A unique parameter for your website's section. The value of the parameter bizId, bizType, or bizCode. It can be taken from the traffic (see the description below).

How to obtain websiteKey and validateId​

Enable Developer Tools, go to the Network tab, activate the CAPTCHA, and look at the requests. Some of them will contain the required parameter values. For example, the parameters:

bizCode: "CMC_register", securityId: "09295759baca4d4fbeae80d9ffeaefd8"

or

bizId: "CMC_register", securityCheckResponseValidateId: "09295759baca4d4fbeae80d9ffeaefd8"

or

bizType: "login", validateId: "ff965ea6216b46f3825fa827ecaf297f"

or

bizId: "login", securityCheckResponseValidateId: "ff965ea6216b46f3825fa827ecaf297f"

The necessary parameters to solve the captcha can be obtained by executing JavaScript:

	let originalBCaptcha = window.BCaptcha;
	let BCaptchaData;
	Object.defineProperty(window, 'BCaptcha', {
		get: function() {
			return function(args) {
				const BCaptcha = new originalBCaptcha(args);
				let BCaptchaShow = BCaptcha.__proto__.show
				BCaptcha.__proto__.show = function(args) {
					BCaptchaData = args;
					return 1;
				};
				return BCaptcha;
			}
		}
	});

Then, you can retrieve the parameters, for example, like this BCaptchaData.securityCheckResponseValidateId.
