I would like to create a new campaign whenever another service sends out a webhook. The email message and the email subject needs to be customized with the content from the webhook but the recipient list and all other information remains the same. 

If I am using the Campaign Management API do the headers and footers still get applied to my email?

Is there a way to have a variable in my template that I could send as a parameter to ZohoCampaigns so that I am doing more of a campaign clone? I would like to continue to manage my templates in Zoho rather than taking them out of the system.
