Voluum on your landing pages
Voluum sends each visitor to your LanderLab page with its click ID on the URL. A hidden field saves it with the lead, and when the form is sent, the page's Webhook integration calls your Voluum postback URL with it, so the lead counts for the source, landing page and offer the visitor came through.
There's no Zap and no extra script to keep running. The lead itself stays in LanderLab's Leads tab, and goes on to your CRM or buyer as usual.
Voluum conversions from the form
The postback goes out on submit with the click ID a hidden field saved from the URL. The webhook is set per page, so each page posts to its own campaign, and only a sent form counts as a lead.
Leads and later stages kept apart
A form fill is rarely the last event: the buyer approves the lead, the offer records a sale. Post the form fill from the page as the lead, let your buyer or network post the later stage, and Voluum can report the two separately by source.
Every lead kept in LanderLab
The lead is also stored in LanderLab's Leads tab with its click ID, page, variant and answers, unless Lead Compliance Delivery is on, so a conversion Voluum is missing can be traced back to the submit.
