How to Integrate PopupKit with SendFox #

So, get the PopupKit Pro version first.

Step 1: Get Your SendFox API Key #

To authorize the connection, you will need an clé API from your SendFox account.

  • Click on your Profile icon in the top-right corner of the dashboard.
  • From the dropdown, select Paramètres du compte.

  • Copy your unique clé API.

Now you have your API Key ready. Let’s move to finding your List ID.

Step 2: Find Your SendFox List ID #

SendFox organizes your subscribers into lists. You will need the List ID of the list where you want your PopupKit leads to be added.

Note: In the current version of SendFox, the Lists option is no longer available as a separate menu item. It is now found inside the Audience section. Follow the steps below to locate it.

  • From the top navigation menu, click on Audience.
  • Inside the Audience section, click on the Lists languette.

Conseil: If you don’t have a list yet, click “+ Create list” in the top-right corner to create one before proceeding.

Step 3: Add SendFox Credentials to PopupKit Settings #

Once you have your API Key and List ID, you need to link them to the PopupKit plugin on your WordPress site.

  • De ton Tableau de bord WordPress, go to PopupKit > Integrations.
