Iframe Setup Guide
This page shows details about how to set up and use the Arkose Bot Manager in the context of an iframe.
Please note that Arkose Bot Manager can host the domain/iframe for use by a customer. Please contact your CSM (Customer Success Manager) or SE for additional information.

How to Use the iframe
The code below shows a full example of how to load the hosted Arkose Bot Manager iframe in lightbox mode.
Before implementation, please reach out to your CSM, as you will need to set up any required public keys to use a hosted iframe template with lightbox mode enabled.
Once setup the customer can then use the hosted iframe url that we provide to them in their implementation.
Example Implementation
This example shows an event listener added to a button that will open load the hosted Arkose Bot Manager iframe in lightbox mode when clicked.

CSS Required
For lightbox mode to work, you need to either add CSS or dynamically update style properties on the hosted iframe DOM element.
The default CSS for the iframe should hide the iframe completely, in our example above we are setting both the height
and width
to 0
and display
to none
to ensure the iframe is not visible unless lightbox mode is activated.
With this we have a CSS class setup that is appended to the iframe when we want to trigger lightbox mode. This class sets the height
and width
of the iframe to 100%
, makes the iframe visible, and positions the iframe on top of the current page. These styles are required to make lightbox mode work correctly.
Inline Mode
Inline mode for our Enforcement Challenge is not a recommended integration approach as it is not a standard integration but there are use cases that may be applicable to you.
The code below shows a full example of how to load the hosted Arkose Bot Manager iframe.

Iframe Events
The iframe events are listed below. Please note the appropriate name and description depends on whether you are using our enforcement or detection components.
Event | Type | Description (Enforcement) | Description (Detection) |
---|---|---|---|
challenge-loaded | event | Challenge has finished loading. | Detection has finished loading. |
challenge-suppressed | event | Challenge will not be presented to the user (Good User Case). | Detection is running and analyzing the user intent. |
challenge-complete | event | Challenge solved / user is validated as good. | Detection is complete. |
challenge-shown | event | Challenge is presented to the user. | Not applicable. |
challenge-iframesize | event | Height and Width of the content within the iframe (For Dynamic Styling). | Not applicable. |
challenge-failed | event | When a challenge is failed more than a configured number of tries. Defaults to no limit value for the trigger. | Not applicable. |
challenge-error | event | Challenge has encountered an error. | Detection or Challenge has encountered an error. |
challenge-warning | event | Challenge has encountered a warning. | Detection or Challenge has encountered a warning. |
challenge-show | event | Before Challenge is presented to the user, only applicable in lightbox mode. | Not applicable. |
challenge-hide | event | After Challenge has been closed or hidden, only applicable in lightbox mode. | After Detection is completed. |
URL Reference
This is a breakdown of the URL which needs to be loaded in the iframe:
- Domain: https://iframe.arkoselabs.com
- Path Options:
- public key: In the examples above this is 11111111-1111-1111-1111-111111111111. Replace this with the public key Arkose Labs gives you.
- URL Params:
- mkt: This is the parameter for passing in a language code. For a list of our supported language codes see Supported Languages.
Please note that Arkose Labs can host the iframe for merchants.
Hosting your Own iframe
Although Arkose Labs generally hosts customer iframes, customers may choose to host their own iframe.
Creating the Iframe Page and Domain
When using this solution:
- A separate domain must be set up.
- A page with the Arkose Bot Manager code must be hosted from it.
Creating the Domain
Create and host the domain using your standard process. An example domain name is <https://iframe.arkoselabs.com
>.
Creating the Hosted Page
The following is example code that could be used to load the Arkose Bot Manager iframe. Please see our Client-Side Instructions for more information on the Arkose Bot Manager implementation. Please select the code view for either our enforcement and detection components, depending on which one you are using.
Please note that some accessibility tools (e.g. Windows narrator) will use the words in the
title
section as spoken text for this iframe. Update the title to comply with your branding strategy.

Please note the following regarding the above sample code:
getAllUrlParams
- A reference function for parsing url parameters if you need to pass any important information through the iframe. An example of important information is language code. See the URL reference section later in this page for more information about URL parameters.
parent.postMessage
- Pass event data back to the parent domain. For example, passing back the session token to submit to the server-side.
challenge-iframeSize
- Not applicable for detection component. This runs on an interval for dynamic resizing of the iframe on the parent element. This data can also be parsed and passed through as part of the Arkose Bot Manager loaded event.
Important Styling
There are a couple styles that will need to be added in order to make the challenge fully accessible and responsive to zooms/smaller screens when the implementation shows the challenge in a Modal fashion. The following code snippet displays the required styles/setup.
<div class="arkose-modal-wrapper" style="display: flex; flex-direction: column;">
<div class="arkose-iframe-holder" style="overflow: auto;">
<iframe title="Arkose Challenge" src="{{hosted iframe url}}">
</div>
</div>
The parent wrapper, arkose-modal-wrapper
, will need to have display: flex
and flex-direction: column
applied to allow the child div to grow within. To arkose-iframe-holder
, overflow: auto
is needed to allow for scrolling.
Accessibility
Due to the nature of iframes, the out of the box accessibility of Arkose’s Challenge can be impacted. This is because iframes cannot hi-jack the focus of the parent page. It is recommended that focus is manually set on the Challenge Loaded
event. Example code:
<script>
window.addEventListener('message', function(event) {
var eventData = JSON.parse(event.data);
if (eventData.eventId === 'challenge-loaded') {
var iframe = document.getElementById('arkoseFrame');
if(iframe) iframe.focus();
}
})
</script>
<body>
<iframe src="https://iframe.arkoselabs.com/<PUBLIC_KEY>/index.html" id="arkoseFrame"></iframe>
