Version: v2

Backend Integration

1. Change the field name in your forms​

The default name of the field in HTML forms was frc-captcha-solution. The new name is frc-captcha-response. Find and replace any old occurences.

2. Change to the new siteverify endpoint URL​

Update the siteverify endpoint URL from

https://api.friendlycaptcha.com/api/v1/siteverify

to

https://global.frcapi.com/api/v2/captcha/siteverify

# or in case you prefer to talk to our EU endpoint from your backend
https://eu.frcapi.com/api/v2/captcha/siteverify

3. Replace the secret and solution field.​

The secret field is no longer used, instead you send your API key in the following header:

Header NameHeader Value
X-API-KeyYour API Key (A1...)

The solution field has been renamed to response in the request body.

4. Handle the new response layout​

In v1 the response from siteverify would look like this:

{
  "success": true|false,
  "errors": [...] // optional
}

The most notable change is that in v2 the errors array is removed, and replaced by a single error object:

{
  "success": false,
  "error": {
    "error_code": "response_invalid",
    "detail": "..." // A human description of the error.
  }
}

For possible values of error_code, see the documentation page. The status codes are unchanged.
