I've read all the threads about this error without success. I think I've done all I could do myself.
I went through the Common Errors guide <https://developers.google.com/adwords/api/docs/common-errors#QuotaCheckError> : *Did you enter your billing information?* *Yes. *I can see billing information in my *Production MCC* account. I've seen AdWords API T&C and accepted it. *Are you having trouble entering your billing information?* *No. *I've added credit card successfully. It was charged for a few cents (like when you link a card to Google Play) from Google Inc. So I'm sure the card was added successfully. *Are you using an unapproved developer token against a production AdWords account?* *No.* I'm using developer token from *Production MCC *against the *test client account* under *Test MCC*. *Still receiving INCOMPLETE_SIGNUP error after completing the above steps?* *Yes! *I've submitted a form to AdWords API Compliance <https://services.google.com/fb/forms/apicontact/> and received an answer with same steps. So the tals way was to use the developer forum. My *Production MCC*: 182-716-2353 My *Test MCC*: 662-907-7712 My *Client *under *Test MCC*: 861-475-5602 In the Developers Console I've created a "web application" logged in with the email of my Test MCC. When a logged in as *Test MCC *owner account I go to my own web application and go through OAuth2 flow, grant access to my application. Then I setup the client library in my web-server application with: Developer Token: Developer token from my *Production MCC*. Client Customer ID: *Client *under *Test MCC* (861-475-5602). OAuth2 Client ID — From the app in Developers Console as described above. OAuth2 Client Secret — Secret of the app. OAuth2 Token: The one from auth flow with Test MCC owner. In debug mode I see Authorization header with the right token and SOAP body contains clientCustomerId. So configs are fine. After all I receive INCOMPLETE_SIGNUP with any api request. -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
