Anash,
Did you mean the AdWords API Compliance form (
https://services.google.com/fb/forms/apicontact/)?
I too have a pending approval AdWords API token and I'm having the exact same issue right now. The form in your reply is for token application, which requires a lot more information that may not be readily available at early development stage (e.g. detail design document and a fully functional web site). In addition, the form clearly says "
DO NOT fill out this form if you just want to use the API for testing", which is exactly what I (and
Guadalupe) was trying to do.
According to the document, a pending approval token should be able to make AdWords API calls against TEST accounts. But the call failed with the TERMS_AND_CONDITIONS_NOT_SIGNED error. BTW, I was using the PHP client library.
I've just filled the AdWords API Compliance form and will update the thread once I get response from them.
