Formstack to HubSpot
No-code platform for online forms, document generation, e-signature and workflow automation.
Formstack data can move into HubSpot, landing mainly in Marketing Hub. 0 of 5 mapped objects move directly; 3 items need manual work and 2 do not move. Plan roughly 1-3 weeks for a small move and 8-16 weeks for a large one.

No price list: cost follows volume, custom objects and how much logic must be rebuilt. Answer four quick questions for a planning range.
The three scenarios
Small migration
<5k submissions, <10 forms
Form rebuild plus CSV or API export.
Mid migration
5k-100k submissions, 10-50 forms
Scripted API export, custom properties and event data.
Large migration
>100k submissions, 50+ forms
Multiple accounts, retained Documents/Workflows and custom objects.

Access, mapping and limits
Start with how data leaves Formstack: what you need to get in, what lands in HubSpot, and what will not.
REST API (V2025) covering forms, submissions, fields, webhooks, folders and partial submissions
A Personal Access Token generated by a Formstack user.
The token follows the creating user's in-app permissions, so use a user who can see all forms and submissions.
Daily limit per access token, which varies by plan. Going over it returns HTTP 429. Older third-party guides cite 14,400 calls per token per day.

How will you move the data?
HubSpot offers an integration for importing records from Formstack.
- You need: A Personal Access Token generated by a Formstack user.
- Permission: The token follows the creating user's in-app permissions, so use a user who can see all forms and submissions.
Native imports often bring over only some data, so check coverage per object in the mapping below.
Export each object, clean it, then import it into HubSpot.
- Submissions API (read, filter by date/search/field values)
- Webhooks
- Per-form CRM integration to HubSpot
- Third-party automation (Zapier, Integrately)
Limits: Daily limit per access token, which varies by plan. Going over it returns HTTP 429. Older third-party guides cite 14,400 calls per token per day.
Migration and sync tools can move more than a plain import. Confirm which objects each one supports before you choose.
Best when volume is high, custom objects are many or automation is heavy. That is the Large scenario: 8-16 weeks, usually phased.

In HubSpot
Hover or tap anything on the left to see where it lands.
| Source object | In HubSpot | Moves | Notes |
|---|---|---|---|
| Form submissions | Contacts | partial | The native integration maps form fields to HubSpot fields for new submissions. Historical submissions need an API export and import. |
| Form definitions/fields | Custom objects | manual | Forms must be rebuilt as HubSpot forms. Submissions can optionally be stored as custom objects if needed. |
| Company/organization field data | Companies | partial | Only if the company is captured as a form field. Map and associate it during import. |
| Uploaded files | Files | manual | Download file-upload field content separately and re-upload it to HubSpot. |
| Event registrations/attendance | Custom objects | manual | Formstack has no native event-production module in the sources. Registrations are ordinary submissions. |
What to expect
They are not portable and must be rebuilt as HubSpot forms.
They are separate products. Retain them or replace them with other tools.
Replace Formstack embeds on site pages with HubSpot forms and the tracking code.
Field labels differ across forms, so each form needs its own mapping.
Consent is stored as ordinary fields, so it must be mapped to HubSpot subscription and consent properties.
Batch the export across days and check your plan's quota.
Check the stored count per form and recover any emailed submissions.
Dedupe on email before import.
Confirm the HubSpot tier before relying on the connector during parallel running.
Data governance and compliance
Decide what is allowed to move before anything is exported. Tick each gate once it is agreed.
