custom columns in the API

[Arthur]

are there plans to make custom columns also available in the API?

Today, I have to download a report with clicks, impressions and then separately a report with conversions and conversionTypeName, flatten this table and then join it with the clicks,impression performance data. 

my target data is a flat table (as in the interface with custom columns) with cost, clicks, impressions and then for example customConversion1, customConversion2.

Hello,

There is no way to do this aside from the procedure you've outlined.

I cannot comment on what features may or may not make future releases. Please make sure to follow our blog to keep up to date with the latest changes.
