We have an integration that had been running fine for some weeks now.
Last night at around 5:44 PM we started getting 403 errors with a message:
You don't have permission to access "http://api.hubapi.com/contacts/v1/contact/createOrUpdate/email/<user email>?" on this server. Reference #18.23111cb8.1491425924.10f706c
Nothing seems to have changed on our end and the access token we’re using to post can read the existing contacts. We’re also able to create new contacts through hubspot forms and via the hubspot web UI.
It sure seems like something has been disabled with our token, so we contacted our Hubspot CSM but they were unable to help and suggested we post here.
