Validation Failed in Content Gateway

Hi Team,

I have created content gateway having Authentication type selected as API Key. The ingestion is failing with error as Validation Failed. I assume it is due to the header is not getting passed in the request because when I am sending the request in API Playground it asked me for the Header Key and Value.

While configuring the Content Gateway connector there is no option to add the header as we have in API Playground or HTTP action , how we will handle this ?

Also is there a way we can see the ingestion logs ?
