We use make.com (same as zapier) to retrieve a list of all our orders and all its details, but there is no option to retreive the "conversion details" Eg: I want to know from which campaign / channel has it converted (e-mail, SEM, direct, etc). They asked me to ask you if there is any API endpoint that would help me retrieve the conversion details from each order?
There is a source_name field on the Order object in our REST API. This field can be used for sales attribution as it will give you the name of the source where the order originated - but you will need to register the channels that the app is managing.
Will this work for your integration with make.com?
