Unexpected ouput generated when using the AdWords keywords generator api

Question

When using the Google Adwords API keyword generator given in this example, I assumed I would get some keywords related to the query I made ("space cruise"). Instead, I get the following:

Keyword with 'space cruise f125bcf7' text and average monthly search volume '5779518' was found with Products and Services categories: [17, 35, 10628, 5].
Keyword with 'red herring b610fbe0' text and average monthly search volume '3613244' was found with Products and Services categories: [56, 57, 43, 10628].
Keyword with 'red herring e969d14a' text and average monthly search volume '4490523' was found with Products and Services categories: [16, 33, 10628, 30].
Keyword with 'red herring 33bb9989' text and average monthly search volume '4773027' was found with Products and Services categories: [41, 10628, 13, 22].
Keyword with 'red herring cc518050' text and average monthly search volume '4650205' was found with Products and Services categories: [12, 10628, 13, 7].
Keyword with 'red herring 5864c829' text and average monthly search volume '5092454' was found with Products and Services categories: [11, 28, 10628, 46].
Keyword with 'red herring ef5efb42' text and average monthly search volume '5313565' was found with Products and Services categories: [26, 44, 10628, 14].
Keyword with 'red herring 8dc2cad8' text and average monthly search volume '4603880' was found with Products and Services categories: [40, 52, 10628, 55].

How should the numbers at the end of the "keyword" be interpreted - is there some way to map it to a real word? I looked at their docs but was unable to find an answer.

Answer 1

The numbers you see at the end are IDs of the product and service category taxonomy of Google Adwords. You can find the human-readable descriptions here.

Also note that Adwords test accounts (which you appear to be using) do not return any meaningful data for the TargetingIdeaService. That's why you see all these "red herring" keywords—well played, Google.
