Checkify
JavaScript SDK available

Build Checkify into your own app or website.

Add one Checkify Pass to your site, choose a request type such as human or age verification, and drop the SDK snippet into your page.

Quickstart 
<script src="https://checkify.me/sdk/v1/checkify.min.js"></script>
<div data-checkify-pass="YOUR_PASS_ID" data-checkify-request="human"></div>

Register your website domain when creating the site in Checkify. The embed works from that domain immediately. Optional DNS/meta/file verification increases your business assurance level.

How it will work

SDK integration flow

The developer flow is based around one Checkify Pass ID, a request type, and a verifiable result on your backend.

Step 1

Create a Checkify Pass

Create a Checkify Pass in the business panel or app. The Pass defines what proof is required, such as human verification, age threshold, or multiple proofs together.

Example Pass

“Confirm the user is human and over 18 before continuing.”

Available now: Checkify Pass creation

Step 2

Add the SDK to your product

Add the JavaScript SDK to your website, app shell, or custom flow. Pass your Checkify Pass ID and request type to launch the correct verification request.

Live example
<script src="https://checkify.me/sdk/v1/checkify.min.js"></script>
<div data-checkify-pass="YOUR_PASS_ID" data-checkify-request="human"></div>
Available now: JavaScript embed

Embed snippet

<script src="https://checkify.me/sdk/v1/checkify.min.js"></script>

<div
  data-checkify-pass="YOUR_PASS_ID"
  data-checkify-request="human"
  data-checkify-text="Verify with Checkify"
></div>

See the integration guide for form binding and server-side verification.

Step 3

Launch the Checkify verification flow

The SDK will open the correct Checkify Pass when the user starts the flow. Depending on the use case, this may use a launch link, QR code, app handoff, or embedded verification prompt.

✓ Open a Checkify Pass from your own UI.
✓ Support website and mobile handoff flows.
✓ Request the proof configured in the Pass.
Available now: Pass start + QR / magic link

Possible launch options

Button launch
User clicks “Verify with Checkify”.
QR launch
User scans a QR code with their phone.
App handoff
User opens Checkify from a mobile experience.

Step 4

Receive and check the verification result

Your product will receive a result when the verification flow completes. Backend checks will help confirm the result before you allow the user to continue.

Planned result examples
{
  "human_verified": true,
  "age_over_18": true,
  "status": "approved"
}
Available now: server verify SDKs

Result handling

Frontend callback
Update your UI when the user completes verification.
Backend status check
Confirm the result server-side before granting access.
Business decision
Continue checkout, allow signup, unlock content, or approve the action.

JavaScript SDK is live. Server SDKs are next.

You can embed Checkify on any registered domain today. Backend helper libraries and webhooks are planned for a later release.

Use now

JavaScript embed, server verify SDKs, WordPress connector, and Checkify Pass setup.

Coming soon

npm publish, webhooks, and signed webhook delivery.
