An event parameter is the detail attached to an event sent to the measurement system: product ID, category, amount, currency, payment method. The event answers what happened; the parameters answer under what conditions. Measurement built without parameters cripples reporting from the start.
GA4 and the advertising platforms' pixels work on this structure. The most common mistake is not sending the value and currency parameters; ROAS then cannot be calculated and bid strategies cannot optimize on value. The second common mistake is writing parameter names differently from page to page: "kategori" and "category" accumulate as two separate dimensions and the report splits in half. An event and parameter dictionary should be written before setup, then verified against a real order once live. In server-side setups the same dictionary is applied on both lines.
