Your first 24 hours - what syncs when
Backfill timelines so you know what is normal.
Connecting starts a large backfill. Some data appears in minutes, some takes days - all of it is normal.
| Data | First appears | Full history |
|---|---|---|
| Campaigns and ad performance | within the first hour | up to ~65 days (Amazon's limit for ads reports) |
| Orders and sales | first hours | up to ~2 years, filling progressively |
| Settlements (actual fees) | first day | Amazon posts settlements on its own two-week cycle |
| Sessions and traffic | first day | backfills day by day (Amazon allows one report per day) |
| Inventory | first hours | current snapshot, then daily history builds |
| Brand Analytics (search terms, market basket) | first day | weekly data, backfills gradually |
What this means practically
- Recent numbers firm up before old ones. The last 30 days are reliable within a day or two; deep history keeps filling in the background.
- Fees start as estimates. Until a settlement covers a period, fees are estimated from your account's own trailing rates and marked as such. When the settlement lands, actuals replace estimates automatically - see Why numbers differ from Seller Central.
- Check progress any time on the connection's data freshness view in Settings, or ask your AI assistant "how fresh is my data?"
