Hi Richard, You should be able to use the developer token of your production MCC on your test MCC by modifying the developerToken field with the production account's developer token. Please see step 1 of this guide <https://developers.google.com/adwords/api/docs/first-request> to figure out which file to include the developer token. For example, the Java library uses the ads.properties file to insert your credentials.
Please let me know if you are still experiencing trouble.
