Internal Server Error - Google Ads API

[Emmanuel Etukudo]

Hi Google Ads Team,

I just registered for a manager account and got test account Developer key. I have tried to make API requests using "Get Campaigns" service but it is returning an error.

Is it because I am using text Developer Token? I would like to know. Although I have just applied for Basic access Level.

Please answer my question on time because I am trying to help a friend complete a project.

Thanks.
