Hello,
A few days ago I requested access to the Account Acitivity API through that form that the documentation was pointing to. We received an email confirming access, but I don’t think it worked.
Whenever I try to register a webhook I get a code “32 Could not authenticate you” error back. I can use any of the regular APIs, I only get this error when using the account activity api.
