Best practices to preserve campaign attribution when payment happens through PIX.
01
Preserve parameters from the first click
UTMs, fbclid, gclid and internal identifiers should follow the buyer all the way to checkout. Otherwise, the sale appears in finance but disappears from media analysis.
Use links that preserve parameters and avoid redirects that clean the URL before checkout.
02
Payment confirmation is also an event
With PIX, the buyer may pay after leaving the page. Payment status must be tracked and sent to pixels, webhooks and reports when confirmation arrives.
