How to Connect adsfox with Systeme.io?

The Systeme.io integration with adsfox allows you to fully automate the sending of leads from your sales funnels and send contact quality data to all major ad systems via server-side tracking / Conversion API. adsfox enables full conversion tracking of sales funnels, including sending events to GA4, Google Ads, and Meta Ads via server-side tracking.
After adding the dedicated script in the Edit header code section, adsfox automatically captures every form in your funnel, saves it in the panel, and then forwards the data to CRM and ad platforms.
This allows you to track not only submitted forms but also qualify leads, analyze their business value, and teach Meta, Google Ads, TikTok, LinkedIn, and GA4 algorithms which contacts actually lead to sales.
The entire process is quick and intuitive, no programming or tools like Zapier, Make, or Stape required, and the setup takes just a few minutes.
How to Connect adsfox with Systeme.io?
1. Log in to your Systeme.io account.
2. Go to the Sites -> Sales funnels tab and then click on the name of your funnel.
3. In the next step, select “Edit page”.

4. Go to settings and then “Edit header code”.

5. Paste the script you download from your adsfox panel and save changes.

You can find the dedicated adsfox script in your adsfox panel under the Lead Acquisition tab, then website script:

Next, from the list, select the platform you use to manage your website. For Systeme.io, this will be “others”. If your site uses reCAPTCHA or GA4, check those options before downloading the script.
If you’re using multiple domains or your form is on a subdomain, also check the 3rd option, i.e., Cross-domain:

After clicking “download script”, the following view will appear:

In the case of using multiple domains or a subdomain, enter them according to the panel view (separated by commas).
Then download the appropriate script. You have two options:
- Copy the embed and add it directly in your system (in this case, Systeme.io—as described in the previous steps).
- You can implement Custom HTML via Google Tag Manager added to your page.
Regardless of which option you choose, remember to save the changes.
After pasting the script in the Edit header code section and saving changes, your Systeme.io site is fully connected to adsfox.
From this point, all new leads are automatically:
- Captured by adsfox,
- Saved in the panel under the Retrieved contacts tab,
- Forwarded to your CRM,
- Marked as new lead / qualified / non-qualified / sales,
- Sent as server-side events via Meta CAPI, Google Ads CAPI, TikTok API, LinkedIn API, and GA4.
This allows you to analyze lead quality, create precise audiences, exclude low-quality leads, and optimize campaigns based on real sales value, not just form cost.
To confirm the integration is correct, perform a test form submission and check if the contact appears in the Retrieved contacts tab in the adsfox panel.
The Systeme.io integration with adsfox enables full conversion tracking—from form to sales—and server-side sending of conversion values, allowing you to optimize ad campaigns for quality and real business results.
