Has the submit form api been deprecated?

[RB_Simon]

I've been using the https://api.hsforms.com/submissions/v3/integration/submit/ end point to submit data from a form on my site for a while now and it has suddenly stopped working.

It produced this error:

{
    "status":"error",
    "message":"Do not integrate against this resource. This internal API is subject to change without notification. Public endpoint documentation: https://developers.hubspot.com/docs/methods/forms/submit_form_v3",
    "errorType":"RESOURCE_NOT_PUBLIC",
    "correlationId":"9cda4d80-d257-4ec9-af62-cf2b6d6d01ec"
}

This quote URL above is a 404.

This page: https://developers.hubspot.com/docs/methods/forms/submit_form_v3 does not suggest that this API should not be used.

Any help would be appreciated.

Hey @RB_Simon, 

I believe this is the exact endpoint that you're using: Submit data for a form | Forms API, is that correct? 

If so, on my end, I was able to send a successful POST request to this form endpoint: https://api.hsforms.com/submissions/v3/integration/submit/portal id/form guid.

In order for me to further troubleshoot this, could you share with me:

1. The page url in which the form is on

2. Portal ID

3. Form ID/name
