For WIC accounts, add a button that prompts a visitor for their number, then have Invoca call them and connect them to your call treatment.
For accounts using Invoca’s legacy Web Integration Code (WIC), you can place a button on your landing page that prompts visitors to enter their phone number when clicked. Invoca then places a call to that visitor — when they answer, they’re connected to your Invoca campaign’s call treatment. This feature, “online click-to-call,” is different from “mobile click-to-call,” which hyperlinks directly to a mobile visitor’s phone app instead.

Setting up an online click-to-call button

  1. Log in to Invoca. In the sidebar menu, click Settings. If you’re on a network account, use the account switcher dropdown to select the Advertiser tied to the campaign you want to use.
  2. In the Advertiser section of Settings, click Web Integration.
  3. Click Advanced Tracking Settings, then scroll to the Tracking Preferences section. In the Display Format dropdown, select Show online click-to-call button, then click Update.
  4. Finish setting up your WIC deployment by following How to Deploy Invoca on an Advertiser’s Landing Page for Affiliate Marketing Using Invoca Web Integration Code (WIC). That article also covers customizing your click-to-call button further using the ctcButtonContent parameter.
Once your WIC code is set up and your landing page is live, visitors will see your click-to-call button as part of your display ad.
