Dear Kakao support,
We have encountered an issue today that the access token retrieved from the previous Kakao Login API flow no longer works for Kakao Moment APIs, such as openapi/v4/adAccounts/pages, as it keeps responding -401 Invalid Token.
Sorry, the following description was caused by the tools we are using, please ignore…
After some investigation, we have realized that we would have to use the new business token.
The business token works for getting the ad account list, however, another issue rises. The scope in your system seems incorrect. In my case, I have called the get campaign list API to list all campaigns under ad account 715207, as follows:
Why am I receiving an error indicating insufficient scopes regarding 703131, which is another ad account, instead of the one I have requested? It does not make any sense to me.
Also, I would like to ask that, for access tokens that worked for Kakao Moment APIs before the Business Token, how long would they work? Is there a expiry deadline?
Finally, it looks like there are no refresh tokens for Business Token, may I assume that they will never expire?
Looking forward to hearing from you,
Thanks!
Sincerely,
Sans Jung
