Auth0 → Iterable · Conversion tracking
Connecting Auth0 to Iterable
Auth0 issues the user identity that everything downstream joins on, which makes it the system that decides whether an anonymous visitor and a paying customer can ever be connected. Iterable orchestrates journeys across email, push, SMS and in-app from one user profile, which means a single mis-shaped event can trigger four channels at once. The join between them succeeds or fails on one thing: whether the user ID or email on the profile reaches the Auth0 user identity before the conversion happens, because Iterable can only match a conversion it can tie back to a click it recognizes.

Founders, marketers, and agency owners describing the before-and-after of their Auth0 → Iterable tracking rebuild — in their own words, on camera.
Why this join usually fails
The user ID or email on the profile never reaches Auth0
The single most common cause. Login flows redirect to a hosted Auth0 domain and back, which breaks the session and can lose an identifier captured before login.
The login redirect losing the acquisition source
The visitor arrives from an ad, clicks sign in, goes to Auth0's domain and comes back as a fresh session. Without deliberate persistence the campaign that produced them is gone at exactly the moment they became identifiable.
One duplicate, four channels
Cross-channel orchestration multiplies the cost of a bad event. Where a duplicate in an ad platform is a reporting error, here it reaches the customer on their phone, in their inbox and inside the app, about a single purchase.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. Iterable shows the user profile with its event history and journey membership. Read the profile, and check whether a duplicate profile was created by the same email arriving in a different case.
Architecture
How Auth0 and Iterable actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
Auth0 holds the truth
Auth0 holds identity, not money. Its value to measurement is that it provides the stable key which lets a pre-signup session and a later subscription be recognised as one person.
Step 2
Iterable needs a click to match
The user identifier, the event name and the data fields the journey conditions reference. A journey branching on a field that arrives empty will take the wrong path silently.
Step 3
The identifier is the bridge
The user ID or email on the profile, captured at the visit and carried into the Auth0 user identity. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send paid conversions keyed on the user identity. Signups are a stage, not revenue.
Step 5
Deduplication at the destination
Iterable does not deduplicate events. A purchase sent twice can advance a journey twice, and because journeys span channels the duplicate can produce an email, a push and an SMS about one order.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the Iterable dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
The user ID or email on the profile present on the account
Visible on the record itself in Auth0, not merely captured somewhere on the site.
Sent from your billing system, keyed on the Auth0 user ID
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Iterable does not deduplicate events. A purchase sent twice can advance a journey twice, and because journeys span channels the duplicate can produce an email, a push and an SMS about one order.
Reconciles with the source
Iterable's count and Auth0's records agree within a few percent over a closed window.
Actually broken
The user ID or email on the profile missing on most records
Login flows redirect to a hosted Auth0 domain and back, which breaks the session and can lose an identifier captured before login.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. The visitor arrives from an ad, clicks sign in, goes to Auth0's domain and comes back as a fresh session. Without deliberate persistence the campaign that produced them is gone at exactly the moment they became identifiable.
Counted twice, or not at all
Cross-channel orchestration multiplies the cost of a bad event. Where a duplicate in an ad platform is a reporting error, here it reaches the customer on their phone, in their inbox and inside the app, about a single purchase.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to Auth0. 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 accounts carrying the user ID or email on the profile
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through Auth0 and into Iterable.
- 3
Check whether the identifier survives the login round trip
Test it on a live login. This is the single most common identity break in products that use hosted authentication.
- 4
Send a test event and read every journey it entered
Not just whether the event arrived — which journeys it triggered and what each one sent. That is the blast radius.
- 5
Read the match rate, not the success message
Iterable shows the user profile with its event history and journey membership. Read the profile, and check whether a duplicate profile was created by the same email arriving in a different case.
Source-of-truth validation
How it gets proven
Against Auth0's own records, not against either platform's dashboard.
- The user ID or email on the profile confirmed present on a live account.
- A real conversion followed from click through Auth0 to Iterable.
- Purchases confirmed on single user profiles with the triggered journeys verified, tested in a non-production project first.
- Paid conversions reconciled per user identity against imported conversions, with identifier survival verified across login.
- 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 Iterable already reports conversions that reconcile against Auth0'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 accounts and count how many carry the user ID or email on the profile. Ten minutes, free, and it tells you whether any of this is worth doing.
- If your product has no authentication, there is no identity to join and session-level attribution is all there is.
- If you send on a schedule rather than on behaviour, a simpler email platform does the job without the cross-channel blast radius.
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 Auth0 → Iterable (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
The user ID or email on the profile on every account
Server-sideCaptured before the conversion and stored where it survives.
Conversions arriving in Iterable
8+ EMQThe event lands on the user profile, evaluates against every running journey, and may trigger sends across several channels immediately.
Reconciled against the source
DedupedAuth0's own records are the reference, not either dashboard.
What gets built
Identifier capture into Auth0
Persist the identifier before the redirect and write it onto the user's app metadata at first login, so it survives every subsequent session.
Event source: your billing system, keyed on the Auth0 user ID
Send paid conversions keyed on the user identity. Signups are a stage, not revenue.
Dispatch to Iterable
The Iterable events API, posted server-side with the user identifier and event fields.
Reversals where they exist
Cancellations reverse against the same identity.
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 Auth0 conversions showing in Iterable?
Almost always because the user ID or email on the profile never reached the Auth0 user identity. Login flows redirect to a hosted Auth0 domain and back, which breaks the session and can lose an identifier captured before login. Measure coverage before debugging the dispatch.
02What identifier does Iterable need?
Iterable resolves to a user by userId or email. Sending an event with an email that does not exist creates a new user rather than updating one, which fragments the profile and means a customer can sit in two journeys simultaneously with neither complete.
03Where should the event come from?
Your billing system, keyed on the Auth0 user ID. Send paid conversions keyed on the user identity. Signups are a stage, not revenue.
04How do I know it worked?
Iterable shows the user profile with its event history and journey membership. Read the profile, and check whether a duplicate profile was created by the same email arriving in a different case.
