First of all, I have to say that English is not my native language, so I apologise for my lousy English.What you asked is pretty ordinary task. So you need to understand how form submitted with fields filled with values. Some values can be intersepted further by service like Zapier. And then Zapier sending email with that value inside email. Pretty simple.
My question was very imprecise, so I will explain with a real example to make sure you understand what exactly do I need.
I would like to take a barcode which is generated by Fooevents plugin, every time when customer buys a ticket, and send it with an email template created with email customizer for woocommerce.
Thank you all for your assistance so far .
