The fastest way to get NOCK running on your site is a single ` ``` Your project token is unique to each project. If you have multiple projects in NOCK, make sure you copy the token for the correct one. ## Attribute reference | Attribute | Required | Description | | --------------- | -------- | --------------------------------------------------------------------------------------------------------------------------- | | `data-token` | **Yes** | Your project token, found in **Settings → Widget** in the Dashboard. | | `data-api-base` | No | The NOCK API base URL. Defaults to `https://nocknock.cloud` — you only need to set this if you are on a custom domain plan. | ## Framework examples ### Plain HTML Add the snippet inside your main layout file or any HTML page where you want the widget to appear, just before ``. ```html theme={null} My App ``` ### Next.js (App Router — `layout.tsx`) In the App Router, add the script to your root `app/layout.tsx` so it loads on every page. Use Next.js's built-in ` ``` ### CMS and website builders Most CMS platforms (WordPress, Webflow, Framer, Squarespace, and similar) have a **custom code** or **footer scripts** section in their site settings. Paste the NOCK snippet there to load it on every page without editing individual templates. ## Verifying the installation Once you've added the snippet, open your site in a browser. The NOCK feedback button should appear in the corner of the page. Click it to open the widget and submit a test ticket — then check your Dashboard to confirm the ticket arrived. If the button doesn't appear, open your browser's developer console and look for any errors related to `nock.js`. The most common causes are a missing or incorrect `data-token` and a script tag placed outside the `` element. See the [Troubleshooting](/widget/troubleshooting) guide for more help. Customize the button's appearance, position, categories, and behavior from the Dashboard. Widget not showing up? Step through common installation problems.
