"Allow blank" API Connector

Hi everyone! I have built an API call with the following optional dynamic parameters:

I have checked the option Allow Blank, is there a way to avoid null values from being sent to the recipient if any of these optional parameters do not have a value?

It’s just a guess, but uncheck “Allow blank”

No way to avoid null what you can do is just enter a space for each field and it should just not send anything? At least that was the case for me and the customer.io API
