Twitter Webhooks Registration

oauth
webhooks

#1

Hi, I’m trying to register for webhooks. I requested for access to the Account Activity BETA program and got the email that it was approved. I’ve also made sure my app was read and write permissions.

However, when calling https://api.twitter.com/1.1/account_activity/webhooks.json (POST), I receive the following response:

{"errors": [{
    "code":261,
    "message":"Application cannot perform write actions. Contact Twitter Platform Operations through https://support.twitter.com/forms/platform."
}]}

I made the request using my own code and postman and the response is the same. I’m using Oauth 1.0a as suggested in other topics and sending all the keys and tokens along.

Does anyone knows what I’m doing wrong? Or could this be a setup problem on Twitter’s side?
