API PHP dont list campaigns and ADD_OPERATION_NOT_PERMITTED

[Snayder Acero]

I am configuring the connection to the API "PHP", to be able to create and list the campaigns of my account I performed the following procedure * Create admin account * from this account create the test account * I generated developer token * I generated credentials from administrator * enter by console the GetRefreshToken.php script where I parameterized the client Id, client Secret, ads API = 0, I do not place scopes. * generates me the 3 data, which I later place in adsapi_php.ini * In this file I also parameterize the development token and the TEST account. Try console to list my campaigns with the GetCampaigns.php script and the result is: Number of results found: 0 attempt by console create a test campaign with the AddCampaigns script and the result is: OperationAccessDenied.ADD_OPERATION_NOT_PERMITTED What is missing from configuring or what should I fix in order for the API to work? Thank you!
