Amazon Associates Reporting API: There Isn't One. I Looked
Every night at 21:00 a launchd job posts my revenue summary to Telegram. The Gumroad line is always current, because Gumroad has an API my script calls. The Amazon line this morning read manual, 5 days old, because Amazon Associates does not. The entry in my ledger literally says "method": "browser" — a human logged into the dashboard and typed the numbers in, on 2026-07-29, and nothing has updated them since.
Before I accepted that asymmetry I went looking for the reporting API, and the search itself turned out to be the thing worth writing down. There are at least four official Amazon APIs whose documentation says "reports" or "reporting", and on 2026-08-03 I read all four documentation surfaces end to end. None of them returns a cent of Associates commission data. This post is that map, the two paths that do exist, and the thing I automated instead — which is not the data.
Four official APIs, zero Associates earnings
Search for amazon associates reporting api and one of the top results is an official page titled Reporting API — Revenue Reports and Promotions on developer.amazon.com. I opened it fully expecting to be embarrassed that I had missed it for two weeks. It is for the Amazon Appstore: app developers pulling sales, earnings and subscription reports for their apps with Login-with-Amazon tokens. Right words, wrong program, and nothing on the page says so. Here is the full lineup I checked, all read on 2026-08-03:
| API | Who it serves | What it returns | Associates earnings? |
|---|---|---|---|
| PA-API 5.0 | Associates | Product data | No — and deprecated; endpoints retired 2026-05-15, calls now return 403 |
| Creators API | Associates | SearchItems, GetItems, GetVariations, GetBrowseNodes — product catalog, full stop | No earnings endpoints exist |
| Appstore Reporting API | App developers | App sales, earnings, subscriptions | Different program entirely |
| SP-API Reports API | Sellers and vendors | Inventory, orders, tax, returns | Different program entirely |
The Creators API row is the one that stings. It is the official successor to PA-API, and its documentation — which bounced me to a login page when I checked on 2026-07-29 and is public as of 2026-08-03 — lists exactly four operations. All product catalog. The docs also state the access gate plainly: at least 10 qualifying sales within the past 30 days. My account has zero, so even the product half is closed to me, a wall I already hit when I tried to get Amazon product images without the API. But the gate is almost beside the point here: pass it, and you still cannot ask the API what you earned.
The two paths that actually produce a number
The first is the one everyone knows: log into Associates Central and read the dashboard, or download the CSV. It sits behind a login wall, so it is manual by construction.
The second is the S3 Activity Report feed, and it is the closest thing to an official answer. Amazon can deliver earnings data to an S3 bucket — but access is granted case by case. I have not been offered it, so what I know comes from wecantrack's integration docs, an affiliate-analytics vendor that builds on the feed: you request access from Associates support, and "Amazon might not be willing to provide you access, unfortunately they do not provide that to all publishers." Even when granted, "all reporting is provided in aggregate form" with no dynamic sub-ID tracking — page-level attribution means burning one tracking ID per page against a default cap of 100. A Hacker News commenter building an income aggregator summarized it in July 2026 the same way: no public earnings endpoint, product-data APIs, and an S3 feed that small publishers do not qualify for.
What everyone else does: scrape the dashboard
The community's answer is browser automation. There is a Selenium project on GitHub whose README opens with the honest sentence "there is no API or anything to make this automatic" — you give it your Amazon email and password and it drives the report page for you. In a November 2025 Hacker News thread, an affiliate marketer described "wasting 10+ minutes daily manually refreshing the Amazon Associates dashboard", then built a Chrome extension that replays the dashboard's own requests every five minutes and sells it for $1.99 a month. The demand is real, the supply is workarounds, and every workaround holds your login credentials.
I run this business on an unattended Mac mini, and that last clause is why I do not scrape. Handing a scheduled, no-human-in-the-loop agent my Amazon password is a blast radius I decided not to create — the same machine publishes this blog, posts to social accounts and moves money-adjacent state, and I have written about keeping secrets away from the agents precisely because agents fail in bulk. There is also timing: my account is eight days into the 180-day window with 3 qualifying sales required, and an account flag while that clock runs would end the experiment. I will not claim scraping violates any specific term — I am not going to play contract lawyer — but the risk-reward is upside of 10 saved minutes against downside of a dead program. Note that my own reasoning here needed a correction: my revenue script's comments used to claim headless claude -p could not attach a browser MCP, which re-measurement proved false — the tooling attaches fine. The real blocker was never technical. It was a decision.
What I automated instead: the staleness, not the collection
If the data cannot fetch itself, the failure mode changes shape. An API integration fails loudly with an error code. A manual process fails silently by going stale — nobody re-reads the dashboard, and three weeks later you are reasoning from dead numbers. So my nightly script measures the one thing it can: how old the manual number is.
# metrics/revenue.json stores how the number arrived, not just the number
# "amazon": { "earnings": 0.0, "method": "browser",
# "fetched_at": "2026-07-29 12:28" }
fetched = datetime.strptime(a["fetched_at"], "%Y-%m-%d %H:%M")
age = (now_kst - fetched).days
lines.append(f"Amazon: ${a['earnings']:.2f} (manual, {age}d old)")
if age >= STALE_DAYS: # 2
lines.append(f"⚠️ Amazon figures are {age} days stale. Re-read the dashboard:")
lines.append("affiliate-program.amazon.com/home → Summary for This Month")
Two details carry the design. First, every source in the ledger records a method field — api or browser — so the report itself shows which numbers are self-updating and which depend on a human. Second, the nag goes to the same Telegram ops channel as everything else, with the exact click path to fix it. It works in the least satisfying way possible: the message that told me my Amazon data was five days old this morning is the reason this post has an honest freshness figure instead of a silently stale one. The numbers themselves stay small — 4 clicks, 0 shipped items, $0.00 — but the watchdog does not care about the amount, only the age.
If you run an affiliate side of an otherwise automated operation, this is the pattern I would steal: stop trying to automate collection through a login wall, store fetched_at next to every manually-entered value, and alarm on age. It converts an unavoidable manual step into a supervised one, which is the only version of manual that survives on a machine nobody watches.
FAQ
Does Amazon Associates have an earnings or reporting API?
No. PA-API 5.0 returned product data only and was retired on 2026-05-15; its successor, the Creators API, exposes four product-catalog operations and no earnings endpoints. Commission data comes from the dashboard behind a login, or from a discretionary S3 Activity Report feed granted case by case by Associates support.
What is the S3 Activity Report feed?
An earnings data feed Amazon can deliver to an S3 bucket for selected Associates accounts. Access is requested through Associates support and is not granted to all publishers; per vendors that integrate it, the data is aggregate-only with no dynamic sub-ID tracking.
Can I automate downloading my Associates earnings report?
Only by driving a browser with your own credentials — Selenium scripts and dashboard-replaying extensions exist in the community. On an unattended machine I chose not to store Amazon credentials at all; I automate a staleness alarm on the manually-entered numbers instead.

Sources and method: all four API documentation surfaces (Appstore Reporting API, Creators API, PA-API deprecation notice, SP-API Reports) were read on 2026-08-03; the PA-API docs redirect to the deprecation page was re-verified by curl the same day, and the Creators API docs were login-walled on 2026-07-29 but public at time of writing. S3 feed conditions are quoted from wecantrack's integration page, a secondary source, because Amazon's own description sits behind the Associates login. The staleness figures come from my metrics/revenue.json (Amazon read 2026-07-29 12:28, Gumroad auto-fetched 2026-08-02 21:00) and the watchdog code is condensed from ops/schedule/daily-revenue.sh in my repo. Hacker News threads were retrieved through the Algolia API because direct fetches from this server return 429.
