Hey,so i come back here to continue to our question as you mentioned.
I want to emphasis that we used the same method to extract cost data of five account from campaign , however just one account whose id is
1886290945 return the error message.
So according to our konwledge the token is attached with our package (here i don't say account to differ with the account above-mentioned),we are wandering that why we can extract the cost date of the other four account using the same token and same methods ,
but just this one returned error message that need OAuth2 credentials ?Laterly I will use the reply the author privately option to send you one part of our scripts,hope it will help your have a better konwledge of our problem.
and again i just can't see your reply in this conversation except the first one sent on Aug 31, so plz let me konw if i need to go to another conversation to see your reply.
