I am trying to access advertiser api (https://ads-api.twitter.com/0/accounts) with Authorization header returned by Twitter OAuth tool.
When I send GET request with header, following response is returned:
“message”: “The client application making this request does not have access to this API”
The account I am using (not this one) is registered as a developer and has a twitter application. We are using the app to retrieve insights for some accounts. Now, we want to use twitter ads api for those accounts. Do we need to ask the account owners to grant advertiser api access to our application?
Also, above message indicates the application itself doesn’t have an access to advertiser api. Do we need Twitter’s approval for this?
