Where to Find Your API URL and API Key
Log in to your ActiveCampaign account.
Click the gear icon (bottom left) to go to Settings.
Click Developer in the left menu.
Copy your API URL (it looks like https://youraccountname.api-us1.com).
Copy your API Key (a long string of letters and numbers).
Paste both values into the ActiveCampaign card on the plugin's Autoresponder tab and click Connect.
How to Find Your List ID
In ActiveCampaign, go to Lists from the main menu.
Click on the list you want to use.
Look at the URL in your browser — the number at the end is your List ID (e.g., .../lists/1 means your List ID is 1).
Tip: Once connected, use the default list dropdown on the ActiveCampaign card to select your list instead of entering the ID manually. Click Refresh Lists if you just created a new list and it does not appear yet (lists are cached for 24 hours).
