Braintree → Amazon Ads · Conversion tracking
Connecting Braintree to Amazon Ads
Braintree is a payment gateway rather than a storefront, so it sits underneath whatever is taking the order and holds the transaction itself. Amazon Ads spans two entirely different situations, and most guidance discusses them as though they were one. The join between them succeeds or fails on one thing: whether a click identifier only for off-Amazon destinations reaches the Braintree transaction before the conversion happens, because Amazon Ads can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
A click identifier only for off-Amazon destinations never reaches Braintree
The single most common cause. Braintree is a gateway, so it sees the payment and not the marketing. The identifier has to be attached at the point your application creates the transaction, through custom fields, or it never enters Braintree at all.
A gateway that knows nothing about marketing
Braintree sees a payment. Whether it can be tied to a click depends entirely on whether your own application attached the identifier when creating the transaction, and most do not.
Per-order attribution promised on Amazon-completed sales
It does not exist and cannot be built. Amazon owns the checkout and does not release the join. Any proposal offering per-order attribution on sales completing inside Amazon is describing something unavailable.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. For off-Amazon conversions, reconcile normally against your own records. For on-Amazon sales, Amazon Attribution is aggregated and delayed by construction — it cannot be reconciled per order and is not meant to be.
Architecture
How Braintree and Amazon Ads actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
Braintree holds the truth
Settled and authorised are different states. Authorisation reserves the funds; settlement is money moving, and reporting on the wrong one produces a persistent gap against your bank.
Step 2
Amazon Ads needs a click to match
For off-Amazon destinations, an event with a value and the click identifier. For on-Amazon conversions, nothing — the measurement is not yours to do and Amazon Attribution provides aggregated reporting instead.
Step 3
The identifier is the bridge
A click identifier only for off-Amazon destinations, captured at the visit and carried into the Braintree transaction. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Fire on settlement rather than authorisation, and note that Braintree's PayPal and wallet flows redirect the buyer away — so the confirmation page is not a reliable trigger.
Step 5
Deduplication at the destination
Only relevant for off-Amazon conversions where both a tag and a server event exist. For on-Amazon purchases the question does not arise, because you are not measuring the conversion at all.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the Amazon Ads dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
A click identifier only for off-Amazon destinations present on the transaction
Visible on the record itself in Braintree, not merely captured somewhere on the site.
Sent from the Braintree transaction settlement webhook
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Only relevant for off-Amazon conversions where both a tag and a server event exist. For on-Amazon purchases the question does not arise, because you are not measuring the conversion at all.
Reconciles with the source
Amazon Ads's count and Braintree's records agree within a few percent over a closed window.
Actually broken
A click identifier only for off-Amazon destinations missing on most records
Braintree is a gateway, so it sees the payment and not the marketing. The identifier has to be attached at the point your application creates the transaction, through custom fields, or it never enters Braintree at all.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. Braintree sees a payment. Whether it can be tied to a click depends entirely on whether your own application attached the identifier when creating the transaction, and most do not.
Counted twice, or not at all
It does not exist and cannot be built. Amazon owns the checkout and does not release the join. Any proposal offering per-order attribution on sales completing inside Amazon is describing something unavailable.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to Braintree. A wrong number that nobody checks is indistinguishable from a right one.
Diagnostic sequence
Diagnostic order
Each step rules out a class of cause. Run them in order and the last one usually has a single explanation standing.
- 1
Count transactions carrying a click identifier only for off-Amazon destinations
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through Braintree and into Amazon Ads.
- 3
Open a settled transaction and check its custom fields
If the identifier is not there, your application never attached it and nothing downstream can recover it.
- 4
Establish which Amazon product and which destination you are running
On-Amazon and off-Amazon are different measurement problems, and conflating them wastes the entire engagement.
- 5
Read the match rate, not the success message
For off-Amazon conversions, reconcile normally against your own records. For on-Amazon sales, Amazon Attribution is aggregated and delayed by construction — it cannot be reconciled per order and is not meant to be.
Source-of-truth validation
How it gets proven
Against Braintree's own records, not against either platform's dashboard.
- A click identifier only for off-Amazon destinations confirmed present on a live transaction.
- A real conversion followed from click through Braintree to Amazon Ads.
- The ad product and destination confirmed in writing before any build, so the right measurement question is being answered.
- A PayPal-funded transaction confirmed to report even though the buyer was redirected away.
- Reconciled over a fully closed window, matched per record rather than on totals.
- Re-checked 30 days later.
Straight talk
When you don't need this
Worth reading before paying anyone, including us.
- If Amazon Ads already reports conversions that reconcile against Braintree's records within a few percent, this join is working and there is nothing to buy.
- Measure identifier coverage yourself first — pull your last hundred transactions and count how many carry a click identifier only for off-Amazon destinations. Ten minutes, free, and it tells you whether any of this is worth doing.
- If your platform already reports orders accurately and Braintree is purely the funding rail, work at the order layer instead — it is closer to the customer.
- If all your Amazon spend drives to Amazon listings, there is no conversion tracking build here — only a reporting exercise in Amazon's own tools.
Who this is for
Honest about who we’re a fit for.
We don’t take every project. Here’s how to tell if we’re right for you.
You’re a great fit if…
- You run Braintree → Amazon Ads (or are migrating to it)
- You spend $5K+/month on paid ads (Meta, Google, TikTok, Microsoft, LinkedIn)
- Your reported ROAS doesn’t match what your bank account is saying
- You want to own your tracking stack — no monthly SaaS fees forever
- You have 2–4 days to do this once and never think about it again
Skip us if…
- You spend less than $500/month on paid ads (browser pixel is fine)
- You want a SaaS dashboard with monthly fees forever (Triple Whale, Hyros)
- You need attribution modeling — we fix the data foundation, not multi-touch reports
- You want a 6-month enterprise consulting engagement (we ship in 4 days)
- You expect us to manage your ad accounts (we don’t — that’s a different service)
If you’re still unsure,book the call anyway— we’ll tell you straight whether we can help.
What working looks like
A click identifier only for off-Amazon destinations on every transaction
Server-sideCaptured before the conversion and stored where it survives.
Conversions arriving in Amazon Ads
8+ EMQOff-Amazon conversions appear against the campaign. On-Amazon sales appear in Amazon's aggregated attribution reporting, delayed.
Reconciled against the source
DedupedBraintree's own records are the reference, not either dashboard.
What gets built
Identifier capture into Braintree
Pass the click identifier into the transaction's custom fields when your server creates the charge. Braintree preserves them and they survive to the webhook and to any later refund.
Event source: the Braintree transaction settlement webhook
Fire on settlement rather than authorisation, and note that Braintree's PayPal and wallet flows redirect the buyer away — so the confirmation page is not a reliable trigger.
Dispatch to Amazon Ads
Conversion upload for off-Amazon destinations. For on-Amazon sales, Amazon's own attribution reporting is the only view.
Reversals where they exist
Braintree exposes refunds and disputes, both carrying the original custom fields, so reversals are straightforward.
Pick the package that fits your ad spend
Fixed-fee, no surprises. If your ad spend is meaningful,server-side tracking is what we recommend— it’s the only setup that survives iOS, Safari ITP and ad blockers.
Browser-side starter

Got questions?
The honestanswers.
No buzzwords, no upsell. If we don’t know, we say so.
01Why aren't my Braintree conversions showing in Amazon Ads?
Almost always because a click identifier only for off-Amazon destinations never reached the Braintree transaction. Braintree is a gateway, so it sees the payment and not the marketing. The identifier has to be attached at the point your application creates the transaction, through custom fields, or it never enters Braintree at all. Measure coverage before debugging the dispatch.
02What identifier does Amazon Ads need?
This is the distinction that decides everything. Sponsored formats driving to an Amazon listing produce conversions inside Amazon's checkout — no click identifier reaches you and no per-order join is available to anyone. Amazon DSP driving to your own site is an ordinary integration where a click identifier lands on your page and can be captured like any other network's. Establish which you are running before anything else.
03Where should the event come from?
The Braintree transaction settlement webhook. Fire on settlement rather than authorisation, and note that Braintree's PayPal and wallet flows redirect the buyer away — so the confirmation page is not a reliable trigger.
04How do I know it worked?
For off-Amazon conversions, reconcile normally against your own records. For on-Amazon sales, Amazon Attribution is aggregated and delayed by construction — it cannot be reconciled per order and is not meant to be.
