Working on a plugin integrating with the Active Campaign API.
What I have is a folder inside third_party containing pi.ActiveCampaign.php with a lib folder containing the API. The class describing the plugin is "Active_Campaign" and the function I want to use with it is "insert_contacts." The plugin appears in the add-ons section just fine, with all my documentation, but when I try to use it in a template:
It appears to not be detecting it. I've tried just using "exp:insert_contacts" as well, same result.
Here's the PHP file, as it is now, if needed (bitbucket repo): https: https://goo.gl/Shm4JN
And for reference, here's the doc I'm following: https://ellislab.com/expressionengine/user-guide/development/plugins.html
