Hello HubSpot Team,<\/P>

\u00a0<\/P>

Our software is currently using the legacy HubSpot Form API for submitting forms<\/STRONG>, specifically this endpoint:<\/P>

\u00a0<\/P>

POST https:\/\/forms.hubspot.com\/uploads\/form\/v2\/{portal_id}\/{form_guid<\/a>}<\/P>

\u00a0<\/P>

We are no longer able to find the API documentation for this endpoint. The only related documentation we\u2019ve found is:<\/P>

\u00a0<\/P>

Legacy Forms v1 API \u2013 Submissions<\/a><\/P>

\u00a0<\/P>

However, this is not the same endpoint that our integration uses.<\/P>

In your changelog post from 2022 (Reminder: Validation change to the Forms API submission endpoints<\/a>), you still reference this uploads\/form\/v2 endpoint under the \u201cWhat this means for developers\u201d section.<\/P>

\u00a0<\/P>

Our question is: Will this endpoint continue to be supported?<\/STRONG><\/P>

\u00a0<\/P>

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\u2019t find any mention of its official deprecation or removal, we\u2019d appreciate any clarification or timeline you can share.<\/P>

\u00a0<\/P>

Thank you for your help!<\/P><\/p>\n","protected":false},"excerpt":{"rendered":"
