The score is based on interactions with your site and enables you to take an appropriate action for your site. Register reCAPTCHA v3 keys on the [reCAPTCHA Admin console](https:\/\/www.google.com\/recaptcha\/admin\/create).\n\nThis page explains how to enable and customize reCAPTCHA v3 on your webpage.\n\n## Placement on your website\nreCAPTCHA v3 will never interrupt your users, so you can run it whenever you like without affecting conversion. reCAPTCHA works best when it has the most context about interactions with your site, which comes from seeing both legitimate and abusive behavior. For this reason, we recommend including reCAPTCHA verification on forms or actions as well as in the background of pages for analytics.\n\n**Note:** reCAPTCHA tokens expire after two minutes. If you're protecting an action with reCAPTCHA, make sure to call `execute` when the user takes the action rather than on page load.\n\nYou can execute reCAPTCHA on as many actions as you want on the same page.\n\n## Automatically bind the challenge to a button\nThe easiest method for using reCAPTCHA v3 on your page is to include the necessary JavaScript resource and add a few attributes to your html button.\n\n1. Load the JavaScript API.\n   ```\n    <script src=\"https:\/\/www.google.com\/recaptcha\/api.js\"><\/script>\n   ```\n2. Add a callback function to handle the token.\n   ```\n    <script>\n   function onSubmit(token) {\n     document.getElementById(\"demo-form\").submit();\n   }\n <\/script>\n   ```\n3. Add attributes to your html button.\n   ```\n   <button class=\"g-recaptcha\" \n        data-sitekey=\"reCAPTCHA_site_key\" \n        data-callback='onSubmit' \n        data-action='submit'>Submit<\/button>\n   ```\n## Programmatically invoke the challenge\nIf you wish to have more control over when reCAPTCHA runs, you can use the `execute` method in `grecaptcha` object. To do this, you need to add a `render` parameter to the reCAPTCHA script load.\n\n1. Load the JavaScript API with your sitekey.\n   ```\n   <script src=\"https:\/\/www.google.com\/recaptcha\/api.js?render=reCAPTCHA_site_key\"><\/script>\n   ```\n2. Call `grecaptcha.execute` on each action you wish to protect.\n   ```\n      <script>\n      function onClick(e) {\n        e.preventDefault();\n        grecaptcha.ready(function() {\n          grecaptcha.execute('reCAPTCHA_site_key', {action: 'submit'}).then(function(token) {\n              \/\/ Add your logic to submit to your backend server here.\n          });\n        });\n      }\n  <\/script>\n   ```\n3. Send the token immediately to your backend with the request to [verify](https:\/\/developers.google.com\/recaptcha\/docs\/verify).\n## Interpreting the score\nreCAPTCHA v3 returns a score (1.0 is very likely a good interaction, 0.0 is very likely a bot). Based on the score, you can take variable action in the context of your site. Every site is different, but below are some examples of how sites use the score. As in the examples below, take action behind the scenes instead of blocking traffic to better protect your site.\n\n| Use case | Recommendation |\n|---|---|\n| homepage | See a cohesive view of your traffic on the admin console while filtering scrapers. |\n| login | With low scores, require 2-factor-authentication or email verification to prevent credential stuffing attacks. |\n| social | Limit unanswered friend requests from abusive users and send risky comments to moderation. |\n| e-commerce | Put your real sales ahead of bots and identify risky transactions. |\n\nreCAPTCHA learns by seeing real traffic on your site.

By default, you can use a threshold of 0.5.\n\n## Actions\nreCAPTCHA v3 introduces a new concept: actions. When you specify an action name in each place you execute reCAPTCHA, you enable the following new features:\n\n- A detailed break-down of data for your top ten actions in the [admin console](https:\/\/g.co\/recaptcha\/admin\/)\n- Adaptive risk analysis based on the context of the action, because abusive behavior can vary.\n\nImportantly, when you verify the reCAPTCHA response, you should verify that the action name is the name you expect.\n\n**Note:** Actions might contain only alphanumeric characters, slashes, and underscores. Actions must not be user-specific.\n\n## Site Verify Response\nMake the request to [verify the response token](https:\/\/developers.google.com\/recaptcha\/docs\/verify) as with reCAPTCHA v2 or Invisible reCAPTCHA.\n\nThe response is a JSON object:\n```\n{\n  \"success\": true|false,      \/\/ whether this request was a valid reCAPTCHA token for your site\n  \"score\": number             \/\/ the score for this request (0.0 - 1.0)\n  \"action\": string            \/\/ the action name for this request (important to verify)\n  \"challenge_ts\": timestamp,  \/\/ timestamp of the challenge load (ISO format yyyy-MM-dd'T'HH:mm:ssZZ)\n  \"hostname\": string,         \/\/ the hostname of the site where the reCAPTCHA was solved\n  \"error-codes\": [...]        \/\/ optional\n}\n```\n### Tips\n1. `grecaptcha.ready()` runs your function when the reCAPTCHA library loads. To avoid race conditions with the `api.js`, include the `api.js` before your scripts that call grecaptcha, or continue to use the [onload callback](https:\/\/developers.google.com\/recaptcha\/docs\/display#explicit_render) that's defined with the v2 API.\n2. Try hooking the `execute` call to interesting or sensitive actions like Register, Password Reset, Purchase, or Play.\n3. Use `https:\/\/www.google.com\/recaptcha\/api.js?trustedtypes=true` to load code compatible with [Trusted Types](https:\/\/web.dev\/trusted-types\/).\n\nWas this helpful?\n\nExcept as otherwise noted, the content of this page is licensed under the [Creative Commons Attribution 4.0 License](https:\/\/creativecommons.org\/licenses\/by\/4.0\/), and code samples are licensed under the [Apache 2.0 License](https:\/\/www.apache.org\/licenses\/LICENSE-2.0).

The score is based on interactions with your site and enables you to take an appropriate action for your site. Register reCAPTCHA v3 keys on the [reCAPTCHA Admin console](https:\/\/www.google.com\/recaptcha\/admin\/create).\n\nThis page explains how to enable and customize reCAPTCHA v3 on your webpage.\n\n## Placement on your website\nreCAPTCHA v3 will never interrupt your users, so you can run it whenever you like without affecting conversion. reCAPTCHA works best when it has the most context about interactions with your site, which comes from seeing both legitimate and abusive behavior. For this reason, we recommend including reCAPTCHA verification on forms or actions as well as in the background of pages for analytics.\n\nYou can execute reCAPTCHA on as many actions as you want on the same page.\n\n## Automatically bind the challenge to a button\nThe easiest method for using reCAPTCHA v3 on your page is to include the necessary JavaScript resource and add a few attributes to your html button.\n\n1. Load the JavaScript API.\n   ```\n    <script src=\"https:\/\/www.google.com\/recaptcha\/api.js\"><\/script>\n   ```\n2. Add a callback function to handle the token.\n   ```\n    <script>\n   function onSubmit(token) {\n     document.getElementById(\"demo-form\").submit();\n   }\n <\/script>\n   ```\n3. Add attributes to your html button.\n   ```\n   <button class=\"g-recaptcha\" \n        data-sitekey=\"reCAPTCHA_site_key\" \n        data-callback='onSubmit' \n        data-action='submit'>Submit<\/button>\n   ```\n## Programmatically invoke the challenge\nIf you wish to have more control over when reCAPTCHA runs, you can use the `execute` method in `grecaptcha` object. To do this, you need to add a `render` parameter to the reCAPTCHA script load.\n\n1. Load the JavaScript API with your sitekey.\n   ```\n   <script src=\"https:\/\/www.google.com\/recaptcha\/api.js?render=reCAPTCHA_site_key\"><\/script>\n   ```\n2. Call `grecaptcha.execute` on each action you wish to protect.\n   ```\n      <script>\n      function onClick(e) {\n        e.preventDefault();\n        grecaptcha.ready(function() {\n          grecaptcha.execute('reCAPTCHA_site_key', {action: 'submit'}).then(function(token) {\n              \/\/ Add your logic to submit to your backend server here.\n          });\n        });\n      }\n  <\/script>\n   ```\n3. Send the token immediately to your backend with the request to [verify](https:\/\/developers.google.com\/recaptcha\/docs\/verify).\n## Interpreting the score\nreCAPTCHA v3 returns a score (1.0 is very likely a good interaction, 0.0 is very likely a bot). Based on the score, you can take variable action in the context of your site. Every site is different, but below are some examples of how sites use the score. As in the examples below, take action behind the scenes instead of blocking traffic to better protect your site.\n\n| Use case | Recommendation |\n|---|---|\n| homepage | See a cohesive view of your traffic on the admin console while filtering scrapers. |\n| login | With low scores, require 2-factor-authentication or email verification to prevent credential stuffing attacks. |\n| social | Limit unanswered friend requests from abusive users and send risky comments to moderation. |\n| e-commerce | Put your real sales ahead of bots and identify risky transactions. |\n\nreCAPTCHA learns by seeing real traffic on your site. For this reason, scores in a staging environment or soon after implementing may differ from production. As reCAPTCHA v3 doesn't ever interrupt the user flow, you can first run reCAPTCHA without taking action and then decide on thresholds by looking at your traffic in the [admin console](https:\/\/g.co\/recaptcha\/admin). By default, you can use a threshold of 0.5.\n\n## Actions\nreCAPTCHA v3 introduces a new concept: actions. When you specify an action name in each place you execute reCAPTCHA, you enable the following new features:\n\n- A detailed break-down of data for your top ten actions in the [admin console](https:\/\/g.co\/recaptcha\/admin\/)\n- Adaptive risk analysis based on the context of the action, because abusive behavior can vary.\n\nImportantly, when you verify the reCAPTCHA response, you should verify that the action name is the name you expect.\n\n## Site Verify Response\nMake the request to [verify the response token](https:\/\/developers.google.com\/recaptcha\/docs\/verify) as with reCAPTCHA v2 or Invisible reCAPTCHA.\n\nThe response is a JSON object:\n```\n{\n  \"success\": true|false,      \/\/ whether this request was a valid reCAPTCHA token for your site\n  \"score\": number             \/\/ the score for this request (0.0 - 1.0)\n  \"action\": string            \/\/ the action name for this request (important to verify)\n  \"challenge_ts\": timestamp,  \/\/ timestamp of the challenge load (ISO format yyyy-MM-dd'T'HH:mm:ssZZ)\n  \"hostname\": string,         \/\/ the hostname of the site where the reCAPTCHA was solved\n  \"error-codes\": [...]        \/\/ optional\n}\n```\n### Tips\n1. `grecaptcha.ready()` runs your function when the reCAPTCHA library loads. To avoid race conditions with the `api.js`, include the `api.js` before your scripts that call grecaptcha, or continue to use the [onload callback](https:\/\/developers.google.com\/recaptcha\/docs\/display#explicit_render) that's defined with the v2 API.\n2. Try hooking the `execute` call to interesting or sensitive actions like Register, Password Reset, Purchase, or Play.\n3. Use `https:\/\/www.google.com\/recaptcha\/api.js?trustedtypes=true` to load code compatible with [Trusted Types](https:\/\/web.dev\/trusted-types\/).\n\nExcept as otherwise noted, the content of this page is licensed under the [Creative Commons Attribution 4.0 License](https:\/\/creativecommons.org\/licenses\/by\/4.0\/), and code samples are licensed under the [Apache 2.0 License](https:\/\/www.apache.org\/licenses\/LICENSE-2.0).

The score is based on interactions with your site and enables you to take an appropriate action for your site. Register reCAPTCHA v3 keys on the [reCAPTCHA Admin console](https://www.google.com/recaptcha/admin/create). This page explains how to enable and customize reCAPTCHA v3 on your webpage. ## Placement on your website reCAPTCHA v3 will never interrupt your users, so you can run it whenever you like without affecting conversion. reCAPTCHA works best when it has the most context about interactions with your site, which comes from seeing both legitimate and abusive behavior. For this reason, we recommend including reCAPTCHA verification on forms or actions as well as in the background of pages for analytics. Note: reCAPTCHA tokens expire after two minutes. If you're protecting an action with reCAPTCHA, make sure to call `execute` when the user takes the action rather than on page load. You can execute reCAPTCHA on as many actions as you want on the same page. ## Automatically bind the challenge to a button The easiest method for using reCAPTCHA v3 on your page is to include the necessary JavaScript resource and add a few attributes to your html button. 1. Load the JavaScript API. ``` <script src="https://www.google.com/recaptcha/api.js"></script> ``` 2. Add a callback function to handle the token. ``` <script> function onSubmit(token) { document.getElementById("demo-form").submit(); } </script> ``` 3. Add attributes to your html button. ``` <button class="g-recaptcha" data-sitekey="reCAPTCHA_site_key" data-callback='onSubmit' data-action='submit'>Submit</button> ``` ## Programmatically invoke the challenge If you wish to have more control over when reCAPTCHA runs, you can use the `execute` method in `grecaptcha` object. To do this, you need to add a `render` parameter to the reCAPTCHA script load. 1. Load the JavaScript API with your sitekey. ``` <script src="https://www.google.com/recaptcha/api.js?render=reCAPTCHA_site_key"></script> ``` 2. Call `grecaptcha.execute` on each action you wish to protect. ``` <script> function onClick(e) { e.preventDefault(); grecaptcha.ready(function() { grecaptcha.execute('reCAPTCHA_site_key', {action: 'submit'}).then(function(token) { // Add your logic to submit to your backend server here. }); }); } </script> ``` 3. Send the token immediately to your backend with the request to [verify](https://developers.google.com/recaptcha/docs/verify). ## Interpreting the score reCAPTCHA v3 returns a score (1.0 is very likely a good interaction, 0.0 is very likely a bot). Based on the score, you can take variable action in the context of your site. Every site is different, but below are some examples of how sites use the score. As in the examples below, take action behind the scenes instead of blocking traffic to better protect your site. \| Use case \| Recommendation \| \|---\|---\| \| homepage \| See a cohesive view of your traffic on the admin console while filtering scrapers. \| \| login \| With low scores, require 2-factor-authentication or email verification to prevent credential stuffing attacks. \| \| social \| Limit unanswered friend requests from abusive users and send risky comments to moderation. \| \| e-commerce \| Put your real sales ahead of bots and identify risky transactions. \| reCAPTCHA learns by seeing real traffic on your site. For this reason, scores in a staging environment or soon after implementing may differ from production. As reCAPTCHA v3 doesn't ever interrupt the user flow, you can first run reCAPTCHA without taking action and then decide on thresholds by looking at your traffic in the [admin console](https://g.co/recaptcha/admin). By default, you can use a threshold of 0.5. ## Actions reCAPTCHA v3 introduces a new concept: actions. When you specify an action name in each place you execute reCAPTCHA, you enable the following new features: - A detailed break-down of data for your top ten actions in the [admin console](https://g.co/recaptcha/admin/) - Adaptive risk analysis based on the context of the action, because abusive behavior can vary. Importantly, when you verify the reCAPTCHA response, you should verify that the action name is the name you expect. Note: Actions might contain only alphanumeric characters, slashes, and underscores. Actions must not be user-specific. ## Site Verify Response Make the request to [verify the response token](https://developers.google.com/recaptcha/docs/verify) as with reCAPTCHA v2 or Invisible reCAPTCHA. The response is a JSON object: ``` { "success": true\|false, // whether this request was a valid reCAPTCHA token for your site "score": number // the score for this request (0.0 - 1.0) "action": string // the action name for this request (important to verify) "challenge_ts": timestamp, // timestamp of the challenge load (ISO format yyyy-MM-dd'T'HH:mm:ssZZ) "hostname": string, // the hostname of the site where the reCAPTCHA was solved "error-codes": [...] // optional } ``` ### Tips 1. `grecaptcha.ready()` runs your function when the reCAPTCHA library loads. To avoid race conditions with the `api.js`, include the `api.js` before your scripts that call grecaptcha, or continue to use the [onload callback](https://developers.google.com/recaptcha/docs/display#explicit_render) that's defined with the v2 API. 2. Try hooking the `execute` call to interesting or sensitive actions like Register, Password Reset, Purchase, or Play. 3. Use `https://www.google.com/recaptcha/api.js?trustedtypes=true` to load code compatible with [Trusted Types](https://web.dev/trusted-types/). Was this helpful?

The score is based on interactions with your site and enables you to take an appropriate action for your site. Register reCAPTCHA v3 keys on the [reCAPTCHA Admin console](https://www.google.com/recaptcha/admin/create). This page explains how to enable and customize reCAPTCHA v3 on your webpage. ## Placement on your website reCAPTCHA v3 will never interrupt your users, so you can run it whenever you like without affecting conversion. reCAPTCHA works best when it has the most context about interactions with your site, which comes from seeing both legitimate and abusive behavior. For this reason, we recommend including reCAPTCHA verification on forms or actions as well as in the background of pages for analytics. You can execute reCAPTCHA on as many actions as you want on the same page. ## Automatically bind the challenge to a button The easiest method for using reCAPTCHA v3 on your page is to include the necessary JavaScript resource and add a few attributes to your html button. 1. Load the JavaScript API. ``` <script src="https://www.google.com/recaptcha/api.js"></script> ``` 2. Add a callback function to handle the token. ``` <script> function onSubmit(token) { document.getElementById("demo-form").submit(); } </script> ``` 3. Add attributes to your html button. ``` <button class="g-recaptcha" data-sitekey="reCAPTCHA_site_key" data-callback='onSubmit' data-action='submit'>Submit</button> ``` ## Programmatically invoke the challenge If you wish to have more control over when reCAPTCHA runs, you can use the `execute` method in `grecaptcha` object. To do this, you need to add a `render` parameter to the reCAPTCHA script load. 1. Load the JavaScript API with your sitekey. ``` <script src="https://www.google.com/recaptcha/api.js?render=reCAPTCHA_site_key"></script> ``` 2. Call `grecaptcha.execute` on each action you wish to protect. ``` <script> function onClick(e) { e.preventDefault(); grecaptcha.ready(function() { grecaptcha.execute('reCAPTCHA_site_key', {action: 'submit'}).then(function(token) { // Add your logic to submit to your backend server here. }); }); } </script> ``` 3.
