We’re unable to help with anything related to API access restrictions via these forums.
In the case of the restriction you’ve posted about, that’s very commonly caused by our antispam systems taking action when an application is used to send unsolicited mentions. That’s only one possible reason, but it is what I hear about the most often. Again, we cannot help with individual applications via the forums, this is just informational.
In most cases where an application is restricted to read-only access, you should be able to reset this on the first occasion via the dashboard, and if the same issue recurs, will need to open a case. Once you’ve done that, you’ll be in the review queue for the agents to get back to you. We do have a backlog at present so they will get to your ticket as soon as possible. Thank you for your patience.
