NexHealth → BigQuery · Conversion tracking
Connecting NexHealth to BigQuery
NexHealth sits between a practice website and the practice management system, syncing appointments both ways for healthcare providers. BigQuery has no attribution model, no deduplication rules and no opinion about your data — which makes it the only destination on this site where every number is exactly as good as the query that produced it. The join between them succeeds or fails on one thing: whether whatever join key you decide on reaches the NexHealth appointment before the conversion happens, because BigQuery can only match a conversion it can tie back to a click it recognizes.

Why this join usually fails
Whatever join key you decide on never reaches NexHealth
The single most common cause. The booking widget is embedded on your site, which is better than most healthcare booking flows, but the identifier still has to be carried into the appointment. Health information must never travel with it.
Appointment reason travelling with the identifier
A booking widget that captures reason-for-visit and passes it onward sends health information to an ad platform. The identifier must stay opaque and unaccompanied.
The warehouse quietly disagreeing with every platform
This is not a bug — it is the point. Your warehouse counts orders; Google counts click-attributed conversions in its window; Meta counts differently again. When the four numbers differ, the warehouse is usually right about revenue and wrong about attribution, and knowing which question you are answering is the whole skill.
Nothing reconciles afterwards
An upload that succeeds is not an upload that matched. BigQuery will not tell you anything is wrong. Verify by querying the table directly against your source system's own totals, and check for duplicate rows on the join key before trusting any aggregate.
Architecture
How NexHealth and BigQuery actually connect
Two systems that know nothing about each other. Everything below exists to give them one shared reference.
Step 1
NexHealth holds the truth
NexHealth's value is real-time availability from systems that were never designed to expose it. The appointment ultimately lives in the practice system.
Step 2
BigQuery needs a click to match
BigQuery needs a schema and consistent types. The failure mode is not rejection, it is silent divergence: a column that arrives as a string in one load and an integer in the next, or a timestamp in the wrong zone, which produces answers that look plausible and are not.
Step 3
The identifier is the bridge
Whatever join key you decide on, captured at the visit and carried into the NexHealth appointment. Without it there is nothing to join on and no tool fixes that.
Step 4
The event source decides reliability
Send attended appointments for new patients, valued at expected patient lifetime rather than a single visit.
Step 5
Deduplication at the destination
Nothing deduplicates for you. Streaming inserts are at-least-once, so a retried load can create duplicate rows, and the only protection is a deduplication step you write and actually run.
Diagnose it honestly
Working vs. broken, side by side
Both states look identical from the BigQuery dashboard, which is why this runs for months before anyone notices.
Normal — not a fault
Whatever join key you decide on present on the appointment
Visible on the record itself in NexHealth, not merely captured somewhere on the site.
Sent from the NexHealth appointment webhook
Server-side, so it does not depend on the customer's browser still being there.
Deduplicated correctly
Nothing deduplicates for you. Streaming inserts are at-least-once, so a retried load can create duplicate rows, and the only protection is a deduplication step you write and actually run.
Reconciles with the source
BigQuery's count and NexHealth's records agree within a few percent over a closed window.
Actually broken
Whatever join key you decide on missing on most records
The booking widget is embedded on your site, which is better than most healthcare booking flows, but the identifier still has to be carried into the appointment. Health information must never travel with it.
Sent from the browser
Anyone who closes the tab, blocks the script or converts without a page load is invisible. A booking widget that captures reason-for-visit and passes it onward sends health information to an ad platform. The identifier must stay opaque and unaccompanied.
Counted twice, or not at all
This is not a bug — it is the point. Your warehouse counts orders; Google counts click-attributed conversions in its window; Meta counts differently again. When the four numbers differ, the warehouse is usually right about revenue and wrong about attribution, and knowing which question you are answering is the whole skill.
Nobody has reconciled it
The dashboard shows a number and no one has compared it to NexHealth. 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 appointments carrying whatever join key you decide on
The ceiling on everything else. Do this before debugging anything downstream.
- 2
Follow one real conversion end to end
From the ad click through NexHealth and into BigQuery.
- 3
Audit exactly what the widget passes onward
Confirm no appointment reason, procedure or clinical field leaves your systems.
- 4
Reconcile warehouse order counts against each platform for one closed window
The gaps localize the problem: a gap against all platforms is a collection issue, a gap against one is that platform's window or matching.
- 5
Read the match rate, not the success message
BigQuery will not tell you anything is wrong. Verify by querying the table directly against your source system's own totals, and check for duplicate rows on the join key before trusting any aggregate.
Source-of-truth validation
How it gets proven
Against NexHealth's own records, not against either platform's dashboard.
- Whatever join key you decide on confirmed present on a live appointment.
- A real conversion followed from click through NexHealth to BigQuery.
- Warehouse order counts and revenue reconciled against the source system for a fully closed window, with duplicates checked on the join key.
- A written statement of what is sent, confirming no clinical field is included.
- 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 BigQuery already reports conversions that reconcile against NexHealth'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 appointments and count how many carry whatever join key you decide on. Ten minutes, free, and it tells you whether any of this is worth doing.
- If your practice system already exposes appointments directly, NexHealth may be a layer you do not need in the measurement path.
- If you have one store and one ad platform, a warehouse is infrastructure you will maintain for a reconciliation you could do in a spreadsheet.
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 NexHealth → BigQuery (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
Whatever join key you decide on on every appointment
Server-sideCaptured before the conversion and stored where it survives.
Conversions arriving in BigQuery
8+ EMQThe row lands in a table you own, joinable to every other table you own, with no window and no expiry.
Reconciled against the source
DedupedNexHealth's own records are the reference, not either dashboard.
What gets built
Identifier capture into NexHealth
Pass the identifier into the widget's supported fields as an opaque value, keeping it entirely separate from any clinical or appointment-reason data.
Event source: the NexHealth appointment webhook
Send attended appointments for new patients, valued at expected patient lifetime rather than a single visit.
Dispatch to BigQuery
Streaming inserts or scheduled batch loads from your order system, with the raw event retained alongside whatever you derive from it.
Reversals where they exist
Cancellations and no-shows reduce the figure, and new-patient no-show rates are meaningful.
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 NexHealth conversions showing in BigQuery?
Almost always because whatever join key you decide on never reached the NexHealth appointment. The booking widget is embedded on your site, which is better than most healthcare booking flows, but the identifier still has to be carried into the appointment. Health information must never travel with it. Measure coverage before debugging the dispatch.
02What identifier does BigQuery need?
There is no vendor identifier here. You choose the key — order ID, user ID, click identifier, hashed email — and you live with the consequences. That is the whole appeal and the whole risk: nothing is standardised for you and nothing is silently wrong in a vendor's favour either.
03Where should the event come from?
The NexHealth appointment webhook. Send attended appointments for new patients, valued at expected patient lifetime rather than a single visit.
04How do I know it worked?
BigQuery will not tell you anything is wrong. Verify by querying the table directly against your source system's own totals, and check for duplicate rows on the join key before trusting any aggregate.
