#How to use

In your visualforce page include the component in the form you want to ensure it is completed by a human being

<c:reCaptcha/> <!-- Use your rendering condition -->

In your controller when validating the form

Boolean isSuccess;
// First parameter is the user recaptcha answer transmitted to the form
// Second parameter is a string,string map with the headers values
isSuccess = reCaptcha.verify(
  ApexPages.currentPage().getParameters().get('g-recaptcha-response'),
  new map<String,String>{'headerKey'=>'headerValue'}
);

// Here is a shortcut to directly
// deal with the Current page headers
isSuccess = reCaptcha.verify(
  ApexPages.currentPage().getParameters().get('g-recaptcha-response')
);

// Then check isSuccess to validate the human filled form
if(isSuccess) {
  // then validate the form
} else {
  // handle the error
}

#How to configure

If you deployed via the "deploy to Salesforce" button, Remote Site Settings to google and custom settings should be added. You just have to configure the Custom Settings accordingly to your Google reCaptcha account

You have to define the default value of the custom settings "reCaptchaGoogle".

Go to Setup => Quick Find Box => Custom Settings => reCaptchaGoogle => Manage Set the default organisation level value :

• PublicKey : Put the value of your google recaptcha public key account
• PrivateKey : Put the value of your google recaptcha private key account
