Captcha API

Getting the captcha

Using captchas are currently free of usage. The API module is quite simple built: Requesting a captcha from https://api.tornevall.net/2.0/captcha/ will return a hash and an image url. You can also call for the captcha with /captcha/getCaptcha.

The getCaptchaResponse looks like this:

"response": {
        "captchaResponse": {
            "imageUrl": "https:\/\/api.tornevall.net\/2.0\/captcha\/getImage\/hash\/b437802a590d7fb50030eb5e4d3522ed61369f0c",
            "imageHash": "b437802a590d7fb50030eb5e4d3522ed61369f0c"
        }
    }

Example of a captcha rendered by the captchaApi:

"response": {
        "getCaptchaResponse": {
            "imageUrl": "https:\/\/api.tornevall.net\/2.0\/captcha\/getImage\/hash\/f3d5f4f46bbf12cefda8398eb09d07e42b117245",
            "imageHash": "f3d5f4f46bbf12cefda8398eb09d07e42b117245"
        }
    }

Test the captcha string

Testing this string against the captchaApi is being made either through (example): https://api.tornevall.net/2.0/captcha/testcaptcha/hash/<imageHash>/response/q23lqctg or https://api.tornevall.net/2.0/captcha/testcaptcha and the rest as POST-content or JSON.

In this case, the response of this query will be:

{
    "response": {
        "testCaptchaResponse": "1"
    }
}

If the control instead fails, the response will throw back an exception with error code 2003: TAPI_PLUGIN_CAPTCHA_STRING_MISMATCH

{
    "response": {
        "responseString": ""
    },
    "errors": {
        "success": "",
        "faultstring": "Captcha test failed",
        "action": "",
        "code": "2003"
    },
    "api": {
        "endPoint": "captcha",
        "verb": "testCaptcha"
    },
    "request": [],
    "client": []
}
