WhatConverts → Instacart Ads · Conversion tracking
Connecting WhatConverts to Instacart Ads
WhatConverts is built to make lead quality visible rather than lead volume, which is the right instinct and only works if somebody actually marks the leads. Instacart sits between a brand and a shopper who is buying from a grocer, which puts two intermediaries between your advertising and the purchase — and neither of them shares the customer with you. The join between them succeeds or fails on one thing: whether Instacart's internal basket match reaches the WhatConverts lead before the conversion happens, because Instacart Ads can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
Instacart's internal basket match never reaches WhatConverts
The single most common cause. Calls, forms and chats each capture the identifier differently, and the marking happens later by a person who may not do it consistently.
Quality data that depends on a human remembering
The feature is excellent and the compliance is the problem. A campaign report built on 40% marked leads is a report on 40% of the evidence, chosen non-randomly.
Out-of-stock spend that still reports impressions
Retail media keeps serving while the item is unavailable at the retailer. The impressions are real, the clicks are real, and the sales cannot happen. Nothing in the ad platform surfaces this — it is visible only in retailer stock data.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. Instacart's reporting is the only source. Reconcile against retailer sell-through and stock data, which is where the real explanation for a weak week usually lives.
Architecture
How WhatConverts and Instacart Ads actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
WhatConverts holds the truth
The quality field is manual. An unmarked lead is an unknown, and a system where half the leads are unmarked reports on a biased half — usually the memorable ones.
Step 2
Instacart Ads needs a click to match
Correct product matching to Instacart's catalogue. If your items are mismapped or out of stock at the retailers your ads reach, spend continues and the attributed sales do not.
Step 3
The identifier is the bridge
Instacart's internal basket match, captured at the visit and carried into the WhatConverts lead. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send leads marked as qualified, with the value assigned, and report the unmarked share so the sample bias is visible.
Step 5
Deduplication at the destination
Nothing on your side to deduplicate. The real hazard is double-counting across retail media networks that each claim the same household's grocery basket.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the Instacart Ads dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
Instacart's internal basket match present on the lead
Visible on the record itself in WhatConverts, not merely captured somewhere on the site.
Sent from the WhatConverts lead record
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Nothing on your side to deduplicate. The real hazard is double-counting across retail media networks that each claim the same household's grocery basket.
Reconciles with the source
Instacart Ads's count and WhatConverts's records agree within a few percent over a closed window.
Actually broken
Instacart's internal basket match missing on most records
Calls, forms and chats each capture the identifier differently, and the marking happens later by a person who may not do it consistently.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. The feature is excellent and the compliance is the problem. A campaign report built on 40% marked leads is a report on 40% of the evidence, chosen non-randomly.
Counted twice, or not at all
Retail media keeps serving while the item is unavailable at the retailer. The impressions are real, the clicks are real, and the sales cannot happen. Nothing in the ad platform surfaces this — it is visible only in retailer stock data.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to WhatConverts. 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 leads carrying Instacart's internal basket match
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through WhatConverts and into Instacart Ads.
- 3
Measure what share of leads are actually marked
Below about 80% the quality reporting is indicative rather than reliable, and the report should say so.
- 4
Cross-check ad delivery against in-stock rates by retailer
This is the most common and most expensive failure in retail media, and it is an operations problem rather than a bidding one.
- 5
Read the match rate, not the success message
Instacart's reporting is the only source. Reconcile against retailer sell-through and stock data, which is where the real explanation for a weak week usually lives.
Source-of-truth validation
How it gets proven
Against WhatConverts's own records, not against either platform's dashboard.
- Instacart's internal basket match confirmed present on a live lead.
- A real conversion followed from click through WhatConverts to Instacart Ads.
- Attributed sales reported separately, cross-checked against in-stock rates for the same period.
- Qualified marked leads reconciled against won work, with the unmarked share stated.
- 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 Instacart Ads already reports conversions that reconcile against WhatConverts'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 leads and count how many carry Instacart's internal basket match. Ten minutes, free, and it tells you whether any of this is worth doing.
- If nobody will mark leads consistently, report volume honestly rather than building quality reporting on a fifth of the data.
- Brands without grocery distribution have nothing to advertise here, and the catalogue work is the whole prerequisite.
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 WhatConverts → Instacart 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
Instacart's internal basket match on every lead
Server-sideCaptured before the conversion and stored where it survives.
Conversions arriving in Instacart Ads
8+ EMQAttributed sales appear in Instacart's reporting under its own model and window.
Reconciled against the source
DedupedWhatConverts's own records are the reference, not either dashboard.
What gets built
Identifier capture into WhatConverts
Capture across all channels, then make the marking part of a routine somebody actually follows rather than an optional field.
Event source: the WhatConverts lead record
Send leads marked as qualified, with the value assigned, and report the unmarked share so the sample bias is visible.
Dispatch to Instacart Ads
No conversion dispatch. Like other retail media, the integration is catalogue accuracy plus a reporting discipline.
Reversals where they exist
Leads re-marked as unqualified reverse.
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.

Got questions?
The honestanswers.
No buzzwords, no upsell. If we don’t know, we say so.
01Why aren't my WhatConverts conversions showing in Instacart Ads?
Almost always because Instacart's internal basket match never reached the WhatConverts lead. Calls, forms and chats each capture the identifier differently, and the marking happens later by a person who may not do it consistently. Measure coverage before debugging the dispatch.
02What identifier does Instacart Ads need?
Instacart attributes ad exposure to items added to a basket inside its own app. There is no identifier of yours anywhere in the chain, and the shopper's relationship is with Instacart and the retailer, not with you. You are buying visibility on a shelf you do not own.
03Where should the event come from?
The WhatConverts lead record. Send leads marked as qualified, with the value assigned, and report the unmarked share so the sample bias is visible.
04How do I know it worked?
Instacart's reporting is the only source. Reconcile against retailer sell-through and stock data, which is where the real explanation for a weak week usually lives.
