API-created webhook for product update missing many fields

[den232]

I am creating a webhook via API.  It can work, if I request the right fields, but the wrong ones cause it to just not fire.  Some fields are spelled weirdly.

product-type MUST be spelled product_type.   

body-html MUST be spelled body_html

tags DOES NOT WORK at all

I cannot retrieve info that is attached to the (default) variant on this product.

Sometimes when I "misspell" a field name, the event just does not fire.

Is there a list of usable fields please?  This guessing thing has me pulling my hairs out ... 

Please advise ... What am I doing wrong?  Thanks jb

Creating a webhook as follows

mutation {

  webhookSubscriptionUpdate (

    id: "gid://shopify/WebhookSubscription/877791117476",

    webhookSubscription: {

    callbackUrl: "https://stranddesigner.com/dev232/productUpdate232.asp",

    format:XML,

    includeFields: ["id", "title", "key", "value", "product_type", "body_html", "tags"],

    metafieldNamespaces: ["strand designer"]

    }

  )

  {

    webhookSubscription { topic id includeFields metafieldNamespaces }

userErrors {

field

message

}

  } }

I would utilize the Rest API documentation along with the sample responses here: https://shopify.dev/docs/admin-api/rest/reference/events/webhook?api[version]=2020-04
