How to replay a failed Stripe-to-HubSpot sync without rebuilding your data
Something in your Stripe™-to-HubSpot sync errors — a rate limit, an expired token, a malformed property, a timeout — and a handful of records never make it across. Nobody notices for days or weeks. When it's finally found, the usual answer is "just resync everything," which is slow, risks creating duplicates, and doesn't tell you what was actually missing or why.
There's a narrower fix, but it depends on understanding two failure modes that behave very differently — and on catching the gap before the window to recover it closes.
Why it happens
HubSpot-side failures fall into two categories that need opposite responses. A 429 (rate limit) or a 5xx from HubSpot is transient — retrying with backoff eventually succeeds. A 400 validation error on a specific property is not transient — retrying the exact same request will fail forever until the underlying data is fixed. Treating both the same way is the single most common reason "just retry it" doesn't work: retrying a bad property value in a loop burns your rate-limit budget on requests that were never going to succeed.
Marketplace apps are rate-limited per installed account, and it isn't raisable. HubSpot caps marketplace OAuth apps at 110 requests per 10 seconds per installed portal — and critically, HubSpot's paid API Limit Increase add-on does not raise this ceiling for marketplace-distributed apps. A backfill or a burst of updates that ignores this ceiling will get throttled, and a naive integration reading only "it failed" without checking why will often retry in a way that makes the throttling worse, not better.
Expired-token failures are common because the token lifetime is shorter than most guides say. HubSpot access tokens last 1,800 seconds — 30 minutes — not the roughly six hours widely assumed in older tutorials and generic integration code. Anything that refreshes reactively, only after getting a 401, rather than proactively ahead of expiry, will show a cluster of failures roughly every half hour on an active integration.
One bad record can silently block others behind it. HubSpot has confirmed that a malformed property on a Contact — an incorrectly formatted website URL, for example — can hold up that contact's sync, which can then hold up invoice or payment syncs that depend on the contact existing first. A single bad field, invisible unless you go looking, can quietly stall a whole chain of records.
Stripe's own event history has a hard expiration. Stripe retains full event payloads for 30 days through the Retrieve Event API, and events can only be resent for roughly the first half of that window. Webhook delivery itself retries for up to three days. If your sync has been broken for longer than that, there is nothing left in Stripe's event stream to replay — the fix has to become a state comparison (what does Stripe say exists right now, versus what does HubSpot have), not an event replay, which is a fundamentally different and heavier job.
Retried writes without an idempotency key create duplicates, not fixes. If a retry isn't keyed to something stable — the Stripe event ID, or the underlying object's ID — replaying a partially-succeeded batch can create a second copy of records that already made it through the first time, which is often the real reason teams end up favoring a full, risky rebuild over a targeted retry.
Stripe's own idempotency keys don't last as long as you'd think, either. A key attached to a Stripe API call is only guaranteed to be honored for a limited window — Stripe may prune it after roughly 24 hours — and reusing a key with different parameters afterward returns an error rather than the original result. That's long enough to protect a single retry loop during a short outage; it is not long enough to be your only defense against a gap spanning several days. Anything you want to safely retry a week later needs its own persistent marker, not just Stripe's key.
What you can do about it today
| Failure | Retryable? | Right response |
|---|---|---|
429 rate limited |
Yes | Back off and retry, honoring any wait time HubSpot returns |
5xx server error |
Yes | Exponential backoff, then retry |
401 expired token |
Yes, after refreshing | Refresh proactively before the 30-minute mark, rather than waiting for the failure |
400 validation error |
No | Fix the offending field first — retrying as-is will fail forever |
| Network timeout | Yes, cautiously | Confirm whether the write actually landed before retrying, to avoid a duplicate |
1. Separate retryable failures from data failures before you do anything else
When a sync job logs an error, check the status code. 429 and 5xx: back off and retry. 400 on a specific field: stop retrying that record and go fix the field it's complaining about first.
2. Give every write a stable idempotency key
Use the Stripe event ID or the object's own ID as part of what identifies the HubSpot write — store it in an internal property if you need to. Zapier and Make both pass the triggering event or object ID through their native Stripe integrations; make sure whatever you build downstream actually uses it to check "have I already applied this," rather than writing blind on every run.
3. Track your own "last successfully processed" marker, independent of Stripe's window
Stripe's event history is not your integration's memory. Keep your own record — even a single timestamp or ID in a spreadsheet — of the last Stripe event or object you know made it into HubSpot successfully. If a gap is found within the last couple of weeks, you may still be able to work from Stripe's event history. Past that window, plan on pulling current object state directly instead.
4. When you've fallen outside the replay window, reconcile object-by-object instead
Pull the current state of the affected Stripe objects directly — the Subscriptions, Invoices and Customers list endpoints hold full history; the events feed does not — and compare it against what's currently in HubSpot, updating only what's actually different. This is slower than a targeted replay but far safer than deleting and re-creating everything, which can destroy HubSpot-side edits — notes, manual associations — that a full resync has no way to know it should preserve.
5. Fix the record, then retrigger only that record
Once you've identified the specific bad property or the specific gap, correct the data and re-run the sync for that one Stripe object rather than the whole account. This is the difference between a five-minute fix and a multi-hour rebuild.
6. Test the replay path on one record before trusting it on a backlog
Before replaying a week's worth of missed events, replay one you already know the correct outcome for, and check the result by hand. A replay mechanism that quietly duplicates or overwrites incorrectly is far better discovered on one record than on five hundred.
Where this breaks down
Most middleware tools only expose "retry the last run," not per-record retry. That reintroduces every record from that run — successes and failures both — which is exactly the duplicate-record risk described above if idempotency wasn't handled going in.
Once you're past Stripe's resend window, there's no equivalent feature in most no-code tools at all. Zapier and Make are built around live event triggers, not "reconstruct three weeks of missed history from current state" — that has to be built separately, usually as a one-off script.
A quietly failing validation rule produces no alert, because "zero errors visible" and "erroring in a way nothing surfaces" look identical from outside the tool. Weeks can pass before anyone notices a gap exists at all.
A rebuild fixes the data but destroys the evidence. Once you've deleted and recreated records to force a clean resync, you've lost the record of what was wrong, when it broke, and for how long — which is exactly what shows up as a question during the next audit or close.
What Trueness does about it
Trueness doesn't have a sync to replay yet. Today it only reads your Stripe account and your HubSpot CRM to build your free Drift Report — it writes nothing to HubSpot, so there is nothing written that could go missing or need a replay. Persisting every Stripe event and offering a targeted, one-click replay is on our roadmap for when Trueness starts writing to HubSpot. If you're running a DIY or no-code sync today, the failure modes above are the real ones to plan around in the meantime.
