How do I connect Amazon Ads, and what if my ad spend is missing or wrong?
Open Settings › Organization › Amazon connections, click the … menu on the account and choose Connect Amazon Ads, or Re-authorize Amazon Ads if it is already connected. Sign in with the Amazon login that manages the account's campaigns. Only an Admin can do this. How the connection works is explained in Connect Amazon Ads.
Checked against Nova's code on November 9, 2026
How do I see what Nova reads?
The PPC column of Amazon connections shows Connected, No data or Not connected. No data means no advertising report came back in the last two days, or the login has expired, was paused or cannot see the account. Click the account's line: the panel names the login used and lists the Profiles Nova reads, each with its spend over 30 days. Compare that list with the profiles in your Amazon Ads console.
A Vendor Central account needs its own Ads connection: a Seller Central account's does not cover it.
I reconnected and see "We could not find the advertising account of seller … with this Amazon login"
The login you used cannot see this account's advertising. The message lists the accounts it does see. Your previous connection is kept. Sign in again with the login that manages the campaigns, or ask the account owner to give your login the Campaign Manager permission in Seller Central, Settings, User Permissions.
If you cannot get that login, click Ask the owner to connect, choose Advertising, pick the account and click Create link. The owner connects from the link without a Nova login.
"Amazon did not list the advertising accounts of this login" means Amazon did not answer in time. Nothing changed: try again a minute later.
Why is ad spend missing or different from Amazon?
| You see | Why | Fix |
|---|---|---|
| Advertising authorization expired | Amazon rejected the connection | Re-authorize Amazon Ads |
| Advertising data missing for a country | Your login has no permission on that marketplace | Give it Campaign Manager on that marketplace, one at a time. Nova picks it up within a day |
| No ad cost before a certain date | Nova loads about 2 months of ads before your Ads connection, 60 days for Sponsored Brands | Import older months (below) |
| The last few days are lower than the console | Amazon revises ad data for about 14 days | Compare older days |
| P&L advertising cost is higher than the console | It adds DSP and Creator Connections to sponsored ads | Compare the console with PPC Spend |
| Amounts differ slightly | Nova shows your organization's currency, converted at each day's rate | See Currencies |
| Advertising data collection is paused | Nova paused it | Write to us in the chat |
Re-authorizing loads the last 2 months of ads again, which fills a gap left by an expired connection.
Can I get advertising costs from before my connection?
Yes, back to the oldest month the Amazon Ads console offers, about 15 months. Ask us in the chat: you export the months from the console and we load them. The imported spend shows in the P&L, the Cockpit and your AI assistant. Campaign, keyword and search term views still start from your connection. See History depth.

For each of my accounts, from which date does Nova hold advertising data? Then show last month's ad spend by marketplace so I can compare it with the Amazon Ads console.
