Manually bind multiple Facebook ad pixel codes in shopify

[xiaoxiaowu]

Manually bind multiple Facebook ad pixel codes in shopify. When I place paid advertisements in my Facebook ad account, I need to create multiple pixels to run ads of different categories. I need to bind multiple pixels in the background of shopify. I hope to use manual codes. The method of binding pixels is used for binding, but currently only the pixel base code is bound. I encountered a problem when adding event codes. I am not sure where to bind the event codes? I need help
