How can we resubscribed contacts who had previsouly unsubscribed via API

[moe1985]

My client doesn't use a hubspot form to optin new marketing and sms marketing contacts. 

They have a form flow on their website that pushes the contact via API into Hubspot. 

They collect email and sms optin through this custom form flow. 

We realized that for their use case, it is possible that a contact may unsubscribe from emails but then at a later date, could complete the form flow and optin. How can we make sure that this re-optin is updated in Hubspot?

@moe1985 - It seems to me that by reinventing most of the integrated subscription management logic that HubSPot provides as standard, you may have painted yourself into a corner with respect to "unsubscribe from all email" actions. The overall effect here is that the parallel databases for 'permissions' get out of sync when clicking on through the standard (required) preference links added to each email.

You have no API option to reset that 'unsubscribe from all' flag within HubSpot - although you could direct the visitor to a simple HubSpot form to re-enable the email flag (new functionality).

Good luck!
