Hi @tscheez- We were able to look into your account, it looks like you did not have access to the Account Activity API - All Activities beta. We went ahead and added access (for the app ID 14466071) to the All Activities beta and set your environment name to: env-beta
At this time, we are only provisioning access for a single Client App in the beta period (per developer account). This will likely change when we launch the generally available product soon.
Let us know if you need any more help.
