How to create a Thread inside an Inbox via API

Develop, Build & Integrate APIs & Integrations

Hi. I have the following stack:

- Non Hubspot form submitted from a website

- The form send an email to an Hubspot inbox with an owned email as FROM and the Sender Email as Reply-To (for obvious reason of deliverability).

- Hubspot doesn’t support the standard Reply-To and is not able to associate the thread to the right contact that is not the owned email in the FROM but the one in the Reply-To.

Now the question is…how can I associate the correct Contact to the sender of the email in the Hubspot Inbox?

Is there an API enpoint to create the inbox thread directly without submitting the form?

Thanks.

or associate an Inbox Thread to a different contact

So looks like it’s not possible and Hubspot doesn’t support the no-reply standard so it’s impossible to send a notification email with the correct sender.
Absurd.
