Pass extra in parameters with webhook event

[hasanagh]

Hey all, its my first post here.

I am developing a simple app which should take extra information from the  cart for example: preferred delivery date. and then shown in an embedded app with order information.

Can I send this bit of extra information with the webhook event (namely create order)?

If not, how do you think I should be doing so?

Thanks!

I would suggest a cart / order attribute: https://community.shopify.com/c/Shopify-Design/Cart-Use-cart-attributes-to-collect-more-information/...

In the webhook they will be stored similarly to: 

"note_attributes": [
  {
    "name": "foo",
    "value": "bar"
  }
]
