ActiveCampaign Form Builder — Build & Sync

Why build ActiveCampaign forms in ConvertFlow

ActiveCampaign's built-in forms work well when the form is a straightforward opt-in feeding an automation. They get limiting when you want the form to qualify the lead before it asks for an email, or route different answers into different automations.

ConvertFlow forms sync into the same ActiveCampaign contact record and trigger the same automations, but add multi-step funnels, conditional paths, custom field values written on every answer, and A/B testing with attribution.

The contacts still live in ActiveCampaign. ConvertFlow is the capture and qualification layer in front of it.

1. Connect ActiveCampaign to ConvertFlow

Head to your ConvertFlow website's Integrations area and click to connect with ActiveCampaign.

In ActiveCampaign, go to Settings → Developer to find your API URL and API key. Both are needed — and note that the API URL is account-specific rather than a shared endpoint, so copy it rather than typing it from memory.

Copy and paste both into ConvertFlow's integration fields.

ActiveCampaign and ConvertFlow are now connected. ConvertFlow starts pulling in your lists and tags, so you can trigger automations and segment leads as visitors submit your forms, landing pages and surveys.

2. Add a form to your campaign

Add your ActiveCampaign form to a ConvertFlow landing page, popup or embed. Click to add an element and choose the "form" element type — start from a form template or build from scratch.

3. Toggle the contact fields you want

Select the form element and switch on the contact fields to request. ConvertFlow's preset fields are already configured to send to your integration's contact fields — first name and email address map to ActiveCampaign automatically.

Each field can be edited from the builder panel — placeholder text, label, required state and more.

4. Verify emails and phone numbers before they reach ActiveCampaign

ConvertFlow can check that an entered email address exists with its provider before the contact syncs. A fake address costs you twice: it triggers an automation that goes nowhere, and it counts toward your ActiveCampaign contact tier.

Pro tip: toggling email validation also exposes an option to allow business emails only — useful on a B2B form.

Phone verification does the same for numbers and formats them to the international E.164 standard.

5. Add consent checkboxes

Scroll below the preset contact fields to find compliance checkboxes:

• Privacy consent: link to your privacy policy and terms of service alongside a required checkbox.
• Marketing consent: if your form gates content but also opts the contact into ongoing marketing, collect consent for it.
• SMS consent: require consent to SMS marketing with the required disclosures.

6. Add custom fields and map them to ActiveCampaign

By clicking to add a field at the end of the fields list, you can add as many custom fields as you'd like.

When naming the field, select from "ActiveCampaign fields" — a dropdown of the custom fields that already exist in your account. ConvertFlow will send the value collected by this form into that field.

The field needs to exist in ActiveCampaign first. If you're building a form around a new attribute, create it there before you start and it'll be waiting in the dropdown.

Choose the field type — text, dropdown, radio selection, paragraph or hidden. Dropdown and radio options can carry score values, useful for qualifying a lead before it reaches an automation.

7. Map survey and quiz answers to ActiveCampaign

Survey elements have a "Map to custom field" dropdown in the builder panel, where you select from your ActiveCampaign custom fields. Each answer is written to the contact's record — which is what makes answer-based segmentation possible.

8. Map ConvertFlow's preset fields to ActiveCampaign

With ActiveCampaign connected, your Integrations page shows a Fields button. Click it to map ConvertFlow's preset contact fields to ActiveCampaign custom fields.

Here's the ActiveCampaign-specific detail worth getting right: copy the field's personalization tag name from ActiveCampaign and paste it into ConvertFlow without the % characters. A field whose tag shows as %JOB_TITLE% goes in as JOB_TITLE. Leaving the percent signs in is the most common reason a mapping silently fails to write.

9. Style the form to match your site

In the Design tab, set spacing, field layout, width, fonts, button colour and roundness, field colour and shadows — so the form looks native to your site rather than bolted on.

10. Configure what happens on submit

In the Actions tab, choose what follows submission — redirect to a URL, jump to another funnel step, display a thank-you message, or open a popup.

Alongside the default action, add automations that fire on submit — including adding the contact to an ActiveCampaign list or applying an ActiveCampaign tag. Both are in the dropdown because ConvertFlow pulled them in when you connected.

Conditional actions are where this earns its place: route by field value so a qualified lead gets a different tag — and therefore enters a different automation — than someone downloading a guide.

11. Report on submissions

The funnel breakdown report shows how many people saw, converted and completed the form, where they dropped off, and which answers they selected — so you can see which qualifying question is costing you leads before the contact ever reaches ActiveCampaign.

12. Segment and personalize for ActiveCampaign contacts

Once answers are landing on ActiveCampaign contact records, build segments on those field values and target your automations against them.

ConvertFlow can also read your ActiveCampaign contact segments and personalize your website for them — so a returning contact already in an automation sees the next step rather than the same capture form.
