How can we help?

Paste one script tag before the closing </body> tag on every page. Replace YOUR_KEY with your API key from the portal.

<script src="https://cdn.incluxa.com/widget.js" data-key="inc_live_YOUR_KEY" async></script>

That's it. The widget appears in the bottom-right corner on every page.

Sign into the INCLUXA Portal and go to API Keys in the sidebar. Click "Create API key", give it a name, and copy the key — it is shown exactly once. If you lose it, revoke it and create a new one.

The script loads asynchronously from our CDN (cdn.incluxa.com). First paint is typically under 500ms on a fast connection. The widget button appears in the bottom-right corner as soon as the script executes — no page reload required.

No. The script tag uses the async attribute, which means it loads in parallel without blocking your page render. The bundle is ~17KB gzipped and served from Bunny CDN with edge nodes worldwide.

No. The entire widget UI is rendered inside a Shadow DOM, which completely isolates its styles from your page. Nothing the widget does will leak into your CSS, and nothing in your CSS will affect the widget.

Three options: (1) Install the free "Insert Headers and Footers" plugin (1M+ installs) and paste the script tag in the footer section — no code required. (2) Add it to your theme's functions.php with wp_footer hook. (3) Edit footer.php directly. The INCLUXA WordPress plugin is also available and adds the widget sitewide without editing code.

Go to Online Store → Themes → Actions → Edit code → Layout → theme.liquid. Find the closing </body> tag near the bottom and paste the script tag immediately before it. Save and your storefront will display the widget. A native Shopify app is coming soon.

In the Webflow Designer, click the gear icon to open Site Settings → Custom Code → Footer Code. Paste the script tag and click Save Changes. You must publish the site after saving — Site Settings changes do not take effect until you publish. A native Webflow extension is coming soon. A native Webflow extension is coming soon.

Paste the script tag into the site's custom code setting. Wix: Settings → Custom code → Add Custom Code, placed in Body - end. Squarespace: Settings → Advanced → Code Injection → Footer. Both need a plan that allows custom code. Native Wix and Squarespace apps are coming soon.

Use next/script with strategy="afterInteractive" in app/layout.tsx (App Router) or pages/_app.tsx (Pages Router). Do not use strategy="beforeInteractive" — the widget depends on the DOM being ready.

Not yet — the @incluxa/a11y-sdk npm package is coming soon. Use the script tag today: it works in React, Next.js, Angular, Vue and plain HTML. When the package ships it will add A11yProvider and useA11y() for React and an IncluxaA11y class for vanilla JS, for teams that need programmatic control.

Use data-key — that is the correct attribute name read by the widget. The attribute data-api-key is not recognized. If your widget is not loading, check that your script tag uses data-key="inc_live_...".

Yes. Add data-position="left" to the script tag:

<script src="https://cdn.incluxa.com/widget.js" data-key="inc_live_YOUR_KEY" data-position="left" async></script>

Yes. Add data-preset="dyslexia-friendly" (or any other preset code) to auto-apply a preset for all visitors before they interact with the widget. Built-in presets: wcag-2.2-aa, dyslexia-friendly, low-vision, adhd-focus, motor-assistance, reading-support.

Yes. Add data-exclude-paths="/checkout,/admin" to the script tag with a comma-separated list of paths where the widget should not render.

1. Open the browser console (F12) and look for errors mentioning cdn.incluxa.com — this indicates a CSP or network block. 2. Confirm your API key starts with inc_live_ and is from the portal API Keys section. 3. Check that the attribute is data-key (not data-api-key). 4. Ensure the script is included on the specific page you are testing. 5. On Webflow, confirm you published the site after saving.

https://api.incluxa.com/api/v1 — all endpoints are prefixed with this URL. Include your API key in every request as the X-Api-Key header.

Your API key is missing, incorrect, or revoked. Check: (1) The X-Api-Key header is present in the request. (2) The key value starts with inc_live_. (3) The key is not revoked in the portal. (4) The key belongs to the correct tenant.

You have hit the rate limit or AI call quota for your plan. The response includes a Retry-After header — wait that many seconds before retrying. For AI calls, check your monthly quota remaining in the portal under Analytics.

Go to Settings → Organization in the portal and enter your HTTPS endpoint URL. INCLUXA will POST JSON events to that URL. Always verify the X-INCLUXA-Signature header using HMAC-SHA256 before processing.

Yes. All list endpoints accept page (default 1) and pageSize (default 50, max 100) query parameters. Responses include totalCount, page, pageSize, and totalPages.

Your plan's page count refers to the number of unique URL paths on your website — not visits or pageviews. INCLUXA counts pages by crawling your sitemap once per month. Homepage + 500 product pages = 501 pages.

The widget keeps running. If your sites stay over your page limit for 30 days, the portal asks you to upgrade before you can keep using it. Going over your page limit never pauses the widget.

Yes. Upgrades take effect immediately. Downgrades take effect at the end of your current billing period. Go to Billing in the portal to change your plan.

Log into the portal and go to Billing → Manage subscription. This opens the Stripe customer portal where you can download invoices, update payment methods, and view billing history.

Yes. Every self-serve plan (Solo, Starter, Pro) starts with a 14-day free trial of every Pro feature. A card is required at sign-up, but nothing is charged until the trial ends: your chosen plan bills automatically on day 15, and we email you a reminder 3 days before the first charge. Cancel any time before then from Billing and you won't be charged. If the trial ends without an active plan, your website widget pauses (your account and settings are kept) until you choose a plan. Looking for something free? The INCLUXA browser extension is free — personal accessibility tools on every website you visit, no account needed.

No accessibility tool makes a site automatically compliant. The widget adds preference tools that help users with disabilities, which improves accessibility and can reduce risk — but ADA compliance requires addressing structural issues in your HTML, which the WCAG Scanner and AI Remediation tools are designed to help with.

The VPAT (Voluntary Product Accessibility Template) documents your site's conformance against WCAG 2.1 AA criteria. It is generated from your most recent WCAG scan data and includes a conformance status (Supports / Partially Supports / Does Not Support) per criterion.

Yes. INCLUXA is built to align with GDPR. The widget does not set tracking cookies. User preference data is stored only if you use the profile API with a student/user ID. We offer a Data Processing Agreement for business customers. See our Privacy Policy for full details.

Yes. Our Data Processing Agreement is available to business customers at no extra cost; see /dpa, and email privacy@incluxa.com for a countersigned copy. Schools and districts sign the district agreement in the portal under Settings → Schools instead.
