A Campaign is the primary organizational object used to configure and send a batch of gifts. It acts as a template for all the settings of a single gifting initiative, including the target Recipient list, the selected Collection or product, the budget, branding, and notification messages.
Use this API to update an existing campaign's configuration, including name, status, and customization settings.
