Frequently Asked Questions

Can I Use Progressive Profiling for My Forms in Knak?
Yes. You can use progressive profiling to hide or show fields based on user input. However, this feature must be configured in Marketo. Knak will display the form behavior based on your Marketo configuration.
Can I Add a Form Redirect URL in Knak?
Yes. You can configure a custom redirect URL in Knak after a form submission. This setting in Knak will override the redirect URL set in Marketo.

This is especially useful if you use one Marketo form across multiple landing pages. You can direct each page to a different thank-you URL without needing to clone the form in Marketo.

🔔 Note: Google Tag Manager (GTM) may interfere with the JavaScript used to set form redirect URLs in Knak.
If you need both GTM and a specific redirect URL:
- Keep the GTM script in Knak
- Sync your landing page to Marketo
- Then update the redirect URL directly in Marketo
Why are Pre-fill settings not working in my Marketo Landing Page?
Why Is Pre-fill Not Working in My Marketo Landing Page?
Pre-fill allows you to automatically populate fields with known user data. This improves conversion rates by reducing form effort for returning users. Knak fully supports form pre-population. However, your form must be configured with pre-fill data in Marketo. Pre-fill setup is not available within Knak.

If pre-fill is not working, check to see if you have a url in your embedded form domain override field in your integration. This forces Marketo to load the form via embed code, which disables pre-fill. Marketo’s official documentation confirms that form pre-fill will not work with embedded forms. The embed method uses the older MktoForms script, which lacks pre-fill logic.

How to Fix It:
- Go to your Marketo integration settings
- Clear the embedded form domain override field
- Apply a small change to your landing page and re-sync
- Or sync the landing page as new
This should restore pre-fill functionality.
