![]() | Using our API web service, upload the CAPTCHA image either by form or base64 format. On how to upload using HTML form please refer to our document here https://api.captchas.io/document/#/endpoints?id=inphp-send-or-upload . |
![]() | From the API endpoint https://api.captchas.io/in.php you will recieve a text based or json based answer that looks like this; OK|91239572 or {'status': 1, 'request': 91239572}. The request value is the CAPTCHA ID which you will use to get the CAPTCHA solved answer using the https://api.captchas.io/res.php API endpoint. |
![]() | Now that we have the CAPTCHA ID, we will now try to get or retrieve the CAPTCHA answer or token. This is done by sending an HTTP request to https://api.captchas.io/res.php with data parameters as key={API_KEY}, action=get, and id={CAPTCHA_ID}. |
