Is there a way or an ideal workaround to add Facebook Instant form submissions into the HubSpot inbox. It currently isnt possible to connect an inbox to non-hubspot forms.
I have played around with Zapier but the ideal solution is to have the form submission contact to be the associated contact to the Hubspot inbox conversation rather than the routing email.
Hi @PrashP, I hope you are doing well!
I can confirm that Lead Ad forms are not supported in the conversations inbox. That being said, I definitely see the value of this feature.
I would like to share an idea from one of my colleagues: @JWarren7:
"I’ve been experimenting with a few different workarounds on my end, and, think I have found a viable way forward.
The easiest solution would be to create a team email, or something along those lines and connect it to the conversations inbox (as well as create a user for it).
Then you could create a workflow that enrolls based off a Lead Ad form and triggers an email to that address every time someone submits a form. You would want to populate that email with all of the relevant property values so that the emails come in the conversations inbox with the necessary submission information."
I hope that clears up your doubts.
Best,
Diana
Hi @DianaGomez
Thank you for your response. Would this solution associate the correct contact to the inbox conversation, or would it associate the sender of the email?
Hi @PrashP, you are welcome 
After reviewing, it would associate the sender of the email. It is a workaround and has their limitations.
Hope this helps clarify.
