Article Summary
✅ Amazon Advertising API does not have a fee, but the real cost is the build: approval, OAuth, access tokens, report requests, parsing, retries, field mapping, and maintenance.
✅ Access tokens are valid for 60 minutes, so a direct build needs working refresh-token logic before it can run as a weekly reporting process.
✅ Gorilla ROI connects Amazon Ads data to Google Sheets through a point-and-click sidebar, handling authentication and attribution re-pulls automatically.
Free API access is not the same as a working ad data connection
Amazon Advertising API doesn't have any additional fees yet.
The only fees Amazon lists are the standard account fees and the campaign costs tied to advertising products. Amazon Ads API
But free access does not mean free implementation.
Before you can get a single row of data lands in your spreadsheet, someone still has to get access approved, handle Login with Amazon authentication, refresh tokens, request the right report, wait for the report to finish, download it, parse it, map the fields, and put the data somewhere your team can use.
You think you are signing up for an API. What you are actually signing up for is a small reporting system your team has to own and maintain.
The Amazon Advertising API gives you access to ad data, not a finished report
The Amazon Advertising API is useful when your team needs programmatic access to Amazon Ads data or campaign operations.
Amazon’s reporting docs say the API supports report types based on campaign structure, and performance can be broken down by campaign, ad group, ad, keyword, and target. Amazon Ads report types
For this article, I am only talking about the reporting side.
Campaign creation, bid changes, keyword pausing, and campaign management are separate jobs. If that is what you need, you are building or buying PPC software. If your goal is weekly ad analysis in Google Sheets, stay focused on report data.
The reporting side can help you pull data such as:
- Sponsored Products campaign performance
- Sponsored Brands campaign performance
- Sponsored Display campaign performance
- Campaign and ad group data
- Keyword and target data
- Search term data where available
- Product or ASIN-level performance where available
- Spend, sales, orders, clicks, impressions, ACoS, ROAS, CTR, CPC, and conversion fields where the report supports them
For metric definitions, use the Amazon advertising metrics guide. This article is about the API decision, not PPC strategy.
The build cost shows up after the first successful pull
A direct API build gets expensive because the first successful pull is only the beginning.
Here is the work your team owns if you build directly:
Amazon Ads says access tokens are valid for 60 minutes.
If your developer only gets the first pull working, the setup may look finished. Then the token expires, the next scheduled pull fails, and your team opens a stale sheet on Monday.
V3 reporting works like a report job, not a spreadsheet export
Amazon Ads V3 reporting requires your system to request a report, wait for Amazon to generate it, download it, and then process it into your destination.
Amazon Ads V3 reporting overview says you can request performance data broken down at levels such as campaign, ad group, ad, keyword, and target.
Plain English: the API does not hand you a clean workbook.
You still have to decide:
- Which ad products you want: SP, SB, SD, or some mix.
- Which report level you want: campaign, ad group, keyword, target, product, or search term.
- Which fields should land in the sheet.
- Which date ranges need to refresh.
- Which raw tab receives the data.
- Which calculation tab reads from it.
That is why I would not build the API connection first. I would design the sheet first.
Start with the tab structure, then decide whether the API is worth owning.
Recent ad numbers can move after you pull them
Amazon ad reporting can change after the first pull because attribution is still being updated.
This is the part that makes self-built sheets feel broken even when the API is doing what Amazon says it will do.
Amazon’s V3 reporting FAQ says that if the attribution window is 14 days, restatement can update attribution up to 42 days after the report date. Amazon Ads attribution restatement page also says attribution metrics may be updated throughout the life of a campaign as Amazon runs restatements.
So your sheet needs a rolling refresh window.
A one-time pull is a snapshot. It is like taking a photo of a scoreboard before the game is over. It is just not final.
For weekly analysis, I would refresh recent dates before your team trusts ACoS, ROAS, attributed sales, or TACoS.
The first sheet should separate SP, SB, and SD data
A useful Amazon Ads sheet keeps Sponsored Products, Sponsored Brands, and Sponsored Display data in separate raw tabs before rolling anything up.
I would start with this structure:
Our Gorilla ROI supported data page lists supported Amazon advertising fields such as CampaignID, Campaign Name, Adgroup ID, Adgroup Name, Spend, Sales, Orders, ROAS, ACOS, Clicks, CTR, Impressions, CPC, and Conversion.
I would keep raw ad data boring. No notes, no manual edits, no formulas.
Example: Calculate in AD_CALCS. Display the data in PPC_ANALYSIS.
Easy Way to Pull Amazon Ad Data into Google Sheets
Build direct when the API connection is part of the product
A direct Amazon Advertising API build makes sense when your team is building software, not when you only need a recurring sheet.
Use the direct API path when you need:
- Internal ad software
- Custom campaign workflows
- Bid automation
- Campaign creation or editing
- Proprietary reporting logic inside a database or warehouse
- A developer already assigned to maintain Amazon Ads data
That last part matters. “We can build it” is not the same as “we will maintain it.”
I would use the direct API if the connection itself becomes part of your company’s software. I would avoid it if the end result is just a spreadsheet your manager opens every Monday.
For the larger Google Sheets structure beyond ad data, use the Amazon seller data to Google Sheets hub.
Use a connector when the output is a working Google Sheet
A connector makes more sense when your goal is recurring Amazon Ads data inside Google Sheets.
Here is the clean decision:
None of these paths is wrong. They solve different jobs.
If your team manages campaigns inside Amazon Ads or a PPC tool, keep doing that. I would not manage PPC from a spreadsheet. I would analyze PPC from one.
For the sales context behind TACoS and product movement, use the Amazon sales tracker in Google Sheets article. For spend planning, use the Amazon advertising budget guide.
Where Gorilla ROI fits
Gorilla ROI fits when your team wants Amazon Ads data in Google Sheets without owning the Amazon Advertising API connection.
Gorilla ROI is a Google Sheets data connector and hub for ecommerce operations. For this use case, it pulls supported Amazon advertising data into Sheets so your team can build analysis tabs without maintaining OAuth, token refresh logic, report jobs, parsing, and field mapping.
The workflow is simple:
- Connect the Amazon account.
- Choose the advertising data pull.
- Send the data to a raw ad tab.
- Build calculations in separate tabs.
- Refresh the same structure again.
That still leaves the thinking to your team. You still choose the date range, decide how to calculate TACoS, separate raw tabs from analysis tabs, and read the numbers.
But the repeated API work stops being your problem.
Claire Davies at GNO Partners, an Amazon agency, said,
“It has saved my team over 40 hours per month by automating the exact data pulls we used to do manually.”
That is where I think Gorilla ROI earns its place. The value is not that you have access to an API. The value is that the ad data lands where your team already works.
When Gorilla ROI is the wrong choice
I would not recommend Gorilla ROI if your team needs to write campaign changes back through the API.
Use the direct Amazon Advertising API if you are building custom bid automation, campaign editing workflows, or an internal ad platform. Use manual exports if your ad reporting is a once-a-month check and one person owns the file.
Use Gorilla ROI when your team already works from Google Sheets and the painful part is getting current Amazon Ads data into the workbook without rebuilding the same report.
That is the line I would draw.
Amazon Advertising API FAQ
What is the Amazon Advertising API?
The Amazon Advertising API gives approved advertisers and partners programmatic access to Amazon Ads data and campaign operations. For reporting, it can provide campaign, ad group, ad, keyword, target, and performance data depending on report type.
Is the Amazon Advertising API free?
Amazon says there are no additional fees from Amazon Ads to use the API. The real cost is implementation and maintenance: approval, OAuth, token refresh, report jobs, parsing, field mapping, monitoring, and fixes.
Do I need a developer to use the Amazon Advertising API?
Yes, for a direct build. Your team needs someone to handle API access, authentication, report requests, parsing, refresh logic, and maintenance.
Why do ACoS and ROAS change after I pull the report?
Amazon can restate attribution after the first report pull. If the attribution window is 14 days, Amazon says restatement can update attribution up to 42 days after the report date. Refresh recent dates before using the sheet for weekly spend analysis.
What ad data can I pull into Google Sheets?
You can pull supported campaign, ad group, keyword, target, product, and performance data such as impressions, clicks, spend, sales, orders, CTR, CPC, ACoS, and ROAS, depending on ad type, report type, and connector support.
Should I build my own API connection or use Gorilla ROI?
Build your own API connection if the connection is part of your software or internal ad system. Use Gorilla ROI if the output you need is Amazon Ads data in Google Sheets for recurring analysis.
Does Gorilla ROI write back to Amazon campaigns?
No. Gorilla ROI pulls advertising performance data into Google Sheets. Campaign changes stay in Amazon Ads or your PPC tool.
