How to remove custom parameter

[road11]

I've got to programmatically remove custom parameters from all keywords in one campaign. I can remove the tracking template by setting it to String.Empty in C#. But nothing I try seems to remove the custom parameters. I've tried setting the key and value to String.Empty, but then I get a TOO SHORT error. How do I remove custom parameters through the API.

This doesn't work...

CustomParameter mParam = new CustomParameter();

mParam.key = String.Empty;

mParam.value = String.Empty;

biddableAdGroupCriterion.urlCustomParameters.parameters =

                new CustomParameter[] { mParam };

Hi Eric,

In order to remove Custom Parameters, you will need to set the field value to null and also set isRemove to true.
