# DNI script 101: how to install and configure it

Setting up Dynamic Number Insertion (DNI) involves configuring your account first, then publishing the script to your website. Complete the steps below in order.

# The 5-step setup process

Before your script can go live, you must complete the account configuration workflow.

### Step 1. Acquire your tracking number

* Go to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
* Click **+ Add**. 
* Choose the source you want to track.
* Pick a number type (Local or Toll-Free).
* Select a number from the list.

### Step 2. Name your tracking number

* Give your number a descriptive name. 
* You can set this during setup or later by clicking the edit (pencil) icon next to any number in [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).

### Step 3. Add a destination number

* Go to [Tracking > Destinations](https://app.nimbata.com/tracking/destinations).
* Click **+ Add**. 
* Enter the phone number where calls should be forwarded. 
* This is where your business receives the call.

### Step 4. Set up a call flow

* Go to [Tracking > Call Flows](https://app.nimbata.com/tracking/call-flows).
* Create a new call flow using the **Simple Call Flow** template. 
* Select your **Destination Number** and save. 
* Then go back to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
* Assign the call flow to your tracking number.

### Step 5. Test your setup

* Then, check [Activity > Calls](https://app.nimbata.com/activity/calls) to verify the test call appears in your logs.

# Publishing the DNI Script

Once your account is configured (all five steps above are complete), you're ready to go live.

### Step 6. Open the script page

Go to [Tracking > Tracking Code](https://app.nimbata.com/tracking/tracking-code) in Nimbata.

### Step 7. Configure your swap targets

This is the most critical step. 
You need to tell Nimbata which phone number on your website to replace.
* **Auto-detection:** Nimbata can scan your page automatically.
* **Span tag (recommended for accuracy):** Wrap your website number in a span tag: `<span class="nimbata">123-456-7890</span>`

You can also toggle additional options here, such as **Single Page Application (SPA)** support or adjusting the **cookie duration**.

# Verifying the Installation

* **Live test:** Visit your site; if you're tracking all channels, the number should swap immediately.
* **Google Ads test:** Visit `www.yoursite.com/?gclid=test` to force a swap for paid search numbers.
* **Built-in checker:** Use Nimbata's website URL checker, located just below the DNI script in Tracking > Tracking Code.

🎉 Numbers swapping correctly? You're live. Next, consider setting up swap groups if you want to track multiple numbers or channels independently.
