"My product requires sending a sample design to the customer after they place an order for them to review and make edits. Is there any direct 'variable event' that can send our trial product into an email? We design the sample product using an external web, so each time there's a design, we have to manually send it to each customer.
P.s. I noticed a new feature called "webhook". What can I do with it?
Thank you very much."
