[hitender_17]

Hello guys, I want to add Facebook pixel script in header tag. In which file or path where i got the header file. Can anyone help me ???

[Rakesh Jesadiya]

You can get header.phtml file from 

vendor/magento/module-theme/view/frontend/templates/html/header.phtml

path.

If you want to add only script you can add it directly from Admin panel.

Go To Content tab from left side,

Click on Design -> Configuration 

Now edit your theme and click on HTML Head section,

add your script inside,

 Scripts and Style Sheets field and save.

Clear cache.
