Hi, I have been accepted into the account activity api beta and went to create a new webhook. I posted to the /account_activity/webhooks endpoint with my https url and the Authorization header as the documentation says. The response I get was error 261, application cannot perform write actions.
My twitter client is new and I have checked that write actions have not been limited. The request as far as I am aware should be correct. If anyone knows how to fix this or is having this error please let me know.
