XLSX or Allegro API — where to get sales data

When Sales Center exports are enough, and when to connect read-only API sync in SalesAmplifier.

Allegro sellers today have two main data sources for offers and sales: XLSX exports from Sales Center and the official API (OAuth, read-only). SalesAmplifier stores both as parallel history streams — not as an either/or choice.

What XLSX still does best

Sales Center reports remain essential where the API does not expose the same metrics:

  • visits and conversion from traffic reports,
  • Allegro Ads (spend, clicks, ROAS) from campaign exports,
  • historical sales by offer and sales by day — especially for long ranges without API window limits.

What the Allegro API adds

After connecting your account (read-only OAuth), sync complements exports with fresher data:

  • offer state (price, stock, status) — snapshots every few hours,
  • orders and checkout lines — for the Live (API) view in Sales,
  • offer change journal (/sale/offer-events) — events from roughly the last 24 hours,
  • billing — fee lines linked to offers.

The API does not replace Ads reports or visits. Combine both sources and use in-app reconciliation when numbers disagree.

Getting started in SalesAmplifier

  1. Connect Allegro in account settings.
  2. Run a manual sync or wait for the schedule (every 3 hours).
  3. In Sales, toggle Live (API) alongside XLSX-based charts.
  4. Keep uploading XLSX where the API has no equivalent (Ads, visits).
