Overview
Integrating ActiveCampaign with FlexiFunnels allows you to automatically collect leads, add contacts to lists, apply tags, and trigger email automation whenever someone submits a form or purchases a product.
There are two ways to connect ActiveCampaign with FlexiFunnels:
- Standard API Integration (Recommended) – Connect ActiveCampaign using your API URL and API Key.
- Custom HTML Form Integration – Embed an ActiveCampaign form using its HTML code.
The Standard API Integration is recommended because it offers better automation, tagging, list management, and product rule support.

Before starting the integration, make sure you have:
- An active ActiveCampaign account.
- Access to your ActiveCampaign API URL and API Key.
- Access to your FlexiFunnels Dashboard.
- Administrator permissions for both accounts.
Step 1: Open Autoresponder Integrations

How to Find Your ActiveCampaign API URL & API Key
