How Custom URL parameters work

Custom URL parameters allow Nimbata to capture additional context from a visitor’s page URL and attach it to tracked calls. This is useful when standard attribution (such as source or campaign) isn’t enough. In essence:

• Nimbata reads specific parameters from the page URL
• The parameter values are stored with the call when a tracking number is used
• The data becomes available in call details and exports

How custom URL parameters are captured

Custom URL parameter tracking works when:

• A visitor lands on a page that contains a Nimbata tracking number
• The page URL includes the parameters you’ve configured (for example, UTM parameters)
• The visitor places a call using that tracking number

At the time of the call, Nimbata stores the parameter values alongside the call record.

How to set up custom URL parameters in Nimbata

Step 1. Go to Data Tools > Sources and go to the 'Custom' tab. Click on the '{ } custom url parameter' button.

Step 2. Name your custom URL parameter and then click on the check mark button.

Your custom URL will appear above it and Nimbata will also display informing you of the successful creation of your custom tracking parameter.

Step 3. Go to Activity > Calls.

Step 4. Click on the three-dotted menu and select 'Edit columns'.

Step 5. Find your custom URL parameter in the 'Edit Columns for Completed Calls' view, in this case 'salesleadscampaign'.

Step 6. Click on the blue arrow button to transfer your custom URL parameter from the 'Available' column to the 'Selected' one and exit the menu.

Step 7. Go back to Activity > Calls. Your custom URL parameter will appear on the last column to the right.

And that was it! From now on, whenever Nimbata tracks a call that contains the keyword in your URL, you will be able to see it here.
