Hello HubSpot Team,
Our software is currently using the legacy HubSpot Form API for submitting forms, specifically this endpoint:
POST https://forms.hubspot.com/uploads/form/v2/{portal_id}/{form_guid}
We are no longer able to find the API documentation for this endpoint. The only related documentation we’ve found is:
Legacy Forms v1 API – Submissions
However, this is not the same endpoint that our integration uses.
In your changelog post from 2022 (Reminder: Validation change to the Forms API submission endpoints), you still reference this uploads/form/v2 endpoint under the “What this means for developers” section.
Our question is: Will this endpoint continue to be supported?
We (and likely many other integrations) are still using it heavily, and a large number of our customers depend on these forms. Since we couldn’t find any mention of its official deprecation or removal, we’d appreciate any clarification or timeline you can share.
Thank you for your help!
