What is the difference between using advertiser token and ad manager token?



Both the Advertiser OAuth Token and the Ads Manager Role OAuth Token will allow you to access an Ads account, manage campaigns, access analytics and create cards on behalf of a User.

Using an Advertiser OAuth Token, rate limits are distinct per Advertiser and you can create Tweets on behalf of a User.

Using an Ads Manager Role Token (also known as a Developer OAuth Token) allows Developer Access via the Twitter Ads UI and Tweet creation is limited to Promoted-Only Tweets, pending granting access to create Tweets.
