In my company we've got a Pro account and we are trying to integrate the information from clients to a platform of our own. We plan on using webhooks and some other elements for this integration/synchronization.
We have also started to use Form API with our contact forms on our web. So far this part is working good. But when authorizing the OAuth for the application I wanted to give it some other scopes to try the other integrations.
I've been working so far on my developer account with a test hubspot account which has everything and it worked good. But when we have tried to authorize the app with the production site on the Pro Hubspot account, it said "This hub doesn't have access to some HubSpot features that are required by this integration.".
As far as I know we have Sales Pro, Marketing Pro and Services Professional, so we should have access to almost everything except for events (or so I see on https://developers.hubspot.com/apisbytier).
But so far it seems that "integration-sync" and "timeline" among others are giving us problems. ¿What am I missing/doing wrong? I cannot seem to find more concrete information on what each scope of the configuration of the app does...
