Hi Teng,
Thank you for the reply.
Upon checking your account, I can see that you have one campaign created here. The type of this campaign is "
App" while the sub-type is "
App pre-registration". Unfortunately, the campaign with sub-type "
App pre-registration" is currently not supported in AdWords API and this the possible reason why you've generated an empty report.
Let me know if you have further questions. Please also follow our
blog as we will post there any updates and new releases about the API.
Regards,
