Hello There,

Could someone please confirm if I am using submit form API (this doesn’t need any user account API for validation), do I still need to migrate to private app?

Please find below the link for the API I am using:  
[https://legacydocs.hubspot.com/docs/methods/forms/submit\_form](https://legacydocs.hubspot.com/docs/methods/forms/submit_form)

I found one related post which has kind of similar question ([https://community.hubspot.com/t5/APIs-Integrations/Submitting-forms-after-migrating-to-quot-Private-Apps-quot-from/m-p/672675#M55310](https://community.hubspot.com/t5/APIs-Integrations/Submitting-forms-after-migrating-to-quot-Private-Apps-quot-from/m-p/672675#M55310)) but this post mentioned that there is no v3 version which raised the confusion.
