Hi,
I am trying to upload Custom Match Audiences using the Google Ads API.
I see the new Audience in the Google Ads Audience Manager, but no matches.
I have tried both sending hashed data and non-hashed (leaving the engine to the hashing).
What could go wrong?
My file looks like this

Note that the column names are mapped to the 'right' names.
Also, I have tried sending using 'wrong' names which throws an error.
Is there a limit to how many rows I can submit?
Do I have to input something in the empty cells in the file?
Hope you can help!
