How to make requests to test account adwords api?

Question

API

According to the instructions https://developers.google.com/adwords/api/docs/tes... I did
1) created a production MCC acc and received a developerToken
2) created a test MCC acc, which, as I understand it, is a normal acc not related to adwords
3 ) received a refresh_token of the test account
4) registered in auth.ini of the client library

• developerToken
  
• clientCustomerId
  
• userAgent
  
• client_id
  
• client_secret
  
• refresh_token
  

When executing php www/adwords/examples/AdWords/v201506/BasicOperations/GetCampaigns.php the response No campaigns were found is returned.
When requesting php www/adwords/examples/AdWords/v201506/BasicOperations/AddCampaigns.php
[OperationAccessDenied.ADD_OPERATION_NOT_PERMITTED @ class campaignmgmt.campaign.MutateAction (ADD) requires CREATE_CAMPAIGN
Tell me what's wrong.

Answer 1

I didn’t find this in the documentation, but by desperate googling and using the method of scientific poke, it was established:
1) php www/adwords/examples/AdWords/v201506/AccountManagement/CreateAccount.php create a new account remember customerID
2) in auth.ini we register the received customerID
Now we We can start companies!
