Create assessments for websites

This page explains how to create an assessment to allow your backend to verify the authenticity of the token that reCAPTCHA Enterprise sends. reCAPTCHA Enterprise sends an encrypted response, the reCAPTCHA response token (also known as token), when the end user triggers an HTML action.

For any type of reCAPTCHA key integration (checkbox or score), you must create an assessment to assess the results of execute() in your backend by submitting the generated token to the assessment endpoint. reCAPTCHA Enterprise processes the submitted token and reports the token's validity and score.

The first 1 million reCAPTCHA Enterprise monthly assessments are free. To continue creating assessments after you reach the free monthly usage limit (1 million assessments per month), you must enable billing for your Google Cloud project. For more information about billing for reCAPTCHA Enterprise, see Billing information.

Before you begin

  1. Prepare your environment for reCAPTCHA Enterprise.
  2. Ensure that you have the following Identity and Access Management role: reCAPTCHA Enterprise Agent (roles/recaptchaenterprise.agent).
  3. Install score-based keys or checkbox keys on your website.
  4. Set up authentication to reCAPTCHA Enterprise.

    The authentication method you choose depends on the environment where reCAPTCHA Enterprise is set up. The following table helps you choose the appropriate authentication method and the supported interface to set up authentication:

    Environment Interface Authentication method
    Google Cloud
    • REST
    • Client libraries
    Use attached service accounts.
    On-premises or a different cloud provider REST Use API keys or Workload identity federation.

    If you want to use API keys, then we recommend securing the API keys by applying API key restrictions.

    Client libraries

    Use the following:

Retrieve a token

Retrieve a token from web pages in one of the following ways:

  • The resolved value of the promise returned by the call to grecaptcha.enterprise.execute().
  • Use the g-recaptcha-response POST parameter when a user submits a form on your site.
  • As a string argument to your callback function if data-callback is specified in either the g-recaptcha HTML tag attribute or the callback parameter in the grecaptcha.enterprise.render method.

You can access each user's token only once. If you need to assess a subsequent action that a user takes on your site, or if a token expires before an assessment is created, you must call execute() again to generate a new token.

Create an assessment

After you set up authentication, create an assessment by sending a request to the reCAPTCHA Enterprise API or by using the reCAPTCHA Enterprise Client Libraries.

To improve detection, we recommend that you pass the following additional values when creating assessments: userAgent, userIpAddress, and ja3.

The way you create an assessment is the same for score-based and checkbox keys.

REST API

Create an assessment by sending a request to the reCAPTCHA Enterprise API. You can use either the gcloud CLI or API key for authentication.

Use the gcloud CLI

Create an assessment using the projects.assessments.create method. Send this request to the v1 API endpoint.

Before using any of the request data, make the following replacements:

  • PROJECT_ID: your Google Cloud project ID
  • TOKEN: token returned from the grecaptcha.enterprise.execute() call
  • KEY_ID: the reCAPTCHA key associated with the site or app. For more information, see reCAPTCHA keys.
  • USER_AGENT: the user agent in the request from the user's device.
  • USER_IP_ADDRESS: the IP address in the request from the user's device.
  • JA3: JA3 fingerprint for the SSL client. We recommend using salesforce/ja3 for computing JA3.
  • USER_ACTION: the user-initiated action that you specified for action in the grecaptcha.enterprise.execute() call, such as login.

    For more information, see Action names.

HTTP method and URL:

POST https://recaptchaenterprise.googleapis.com/v1/projects/PROJECT_ID/assessments

Request JSON body:

{
  "event": {
    "token": "TOKEN",
    "siteKey": "KEY_ID",
    "userAgent": "USER_AGENT",
    "userIpAddress": "USER_IP_ADDRESS",
    "ja3": "JA3",
    "expectedAction": "USER_ACTION"
  }
}

To send your request, choose one of these options:

curl

Save the request body in a file named request.json, and execute the following command:

curl -X POST \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
"https://recaptchaenterprise.googleapis.com/v1/projects/PROJECT_ID/assessments"

PowerShell

Save the request body in a file named request.json, and execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
-Method POST `
-Headers $headers `
-ContentType: "application/json; charset=utf-8" `
-InFile request.json `
-Uri "https://recaptchaenterprise.googleapis.com/v1/projects/PROJECT_ID/assessments" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

{
  "tokenProperties": {
    "valid": true,
    "hostname": "www.google.com",
    "action": "homepage",
    "createTime": "2019-03-28T12:24:17.894Z"

    "expectedAction": "USER_ACTION"
  },
  "name": "projects/PROJECT_NUMBER/assessments/b6ac310000000000"
}

We recommend using any JSON parsers in the non-strict parsing mode to prevent any outages if any additional fields are introduced to the JSON response.

Use an API key

Create an assessment using the projects.assessments.create method. Send this request to the v1 API endpoint.

Before using any of the request data, make the following replacements:

  • API_KEY: API key associated with the current project
  • PROJECT_ID: your Google Cloud project ID
  • TOKEN: token returned from the grecaptcha.enterprise.execute() call
  • KEY_ID: the reCAPTCHA key associated with the site or app. For more information, see reCAPTCHA keys.
  • USER_AGENT: the user agent in the request from the user's device.
  • USER_IP_ADDRESS: the IP address in the request from the user's device.
  • JA3: JA3 fingerprint for the SSL client. We recommend using salesforce/ja3 for computing JA3.
  • USER_ACTION: the user-initiated action that you specified for action in the grecaptcha.enterprise.execute() call, such as login.
