Adding product Y automatically when clicking add to cart for product X

[Stormmmneo]

Hi!
May I know or get some help regarding adding a freebie product Y that shows up in the cart drawer when clicking on add-to-cart for product X? 

An example is the image below where the second product is added automatically when a customer add the crystal hair to cart.

I've tried a few ways with the product ID through the const form but i think i may be adding it wrongly



thanks so much!

Hi @Stormmmneo ,

You can write a custom code which will watch the cart data and when it matched with your criteria and fire script to add free bee item.

you can use code provided in below URL to add freebie in account.
