Consultants selling packages from Webflow
A consultant lists three packages on Webflow. Each package adds a different tag, and an ActiveCampaign automation books the kickoff call for that tag.

Webflow hosts the page, Plandalf takes payment, and a Send Webhook step can create the buyer in ActiveCampaign with a tag.
No credit card required. No coding required.
Webflow
ActiveCampaignPlandalf has no native ActiveCampaign steps, and it does not read Webflow forms. A Webflow button opens the Plandalf checkout; after payment a Send Webhook step can call ActiveCampaign's contact sync API. ActiveCampaign automations can post to a Plandalf catch URL to enrol people in a promo.
| Event | From and to | Through | What happens |
|---|---|---|---|
| Checkout opened | Webflow → Plandalf | The button carries data-plandalf-present, and the SDK script sits once in the site's Footer code. | |
| Checkout completed | Plandalf → ActiveCampaign | Webhook | Send Webhook posts to /api/3/contact/sync on your ActiveCampaign account URL, with an Api-Token header and a contact object holding the email, name and tags. |
| Tag added or form submitted | ActiveCampaign → Plandalf | Webhook | An automation with a Webhook action can call a Plandalf Webhook Trigger URL. Plandalf's own notes say ActiveCampaign sends form-encoded data, so check the payload in the trigger's Test tab. |
| Countdown in an email | Plandalf → ActiveCampaign | By hand | A countdown image tag goes into an HTML block in a campaign, with %EMAIL% filling the ref value for each recipient. |
You need your ActiveCampaign API URL and API token, found in the account's developer settings.
Add your Plandalf script to Footer code, set data-plandalf-present on the buy button in Element settings, Custom attributes, and publish.
Note your account's API URL and create or copy an API token from its developer settings. Check ActiveCampaign's developer docs for the current location of both.
In Automation, My Sequences pick Plandalf, Checkout Completed and the Webflow offer. Pick a recent checkout as the sample on the Test tab.
Add Plandalf, Send Webhook. Use POST, your account's contact sync URL, an Api-Token header, and a JSON payload shaped as a contact object with email set to {{trigger.customer_email}}, firstName and a tags list such as customer.
Run the test. ActiveCampaign answers 201 for a new contact and 200 for an existing one. Then build an ActiveCampaign automation that starts when the tag is added.

A site offering a paid trial adds the buyer to a list and starts a nurture automation. A Plandalf countdown image in the final email pushes the upgrade.
