Unable to access account activity api

[amineaffes]

Hello,
I’ve been working on twitter api for more than 4 months, everything was working just fine but today i got {“errors”:[{“code”:89,“message”:“Invalid or expired token.”}]}.
Anyone can tell me why i’m getting this error ?
Thanks in advance

What endpoint are you calling? What code are you using?

hello andy,
i used to subscribe to my webhook and add my welcome message and my bots.
but yesterday, i even can’t subscribe to my webhook and i get “errors”:[{“message”:“Sorry, that page does not exist”,“code”:34}]}’ from twitter although my webhook is valid. By the way, i’m using node js to communicate with twitter api.
Another question : Is this error related to the account activity api migration to premium ?
