Webhook for order updated sends tags as strings

[longinoa]

I am writing an app to change tags on specific orders. I notice that while the order graphql specifies tags as string[], you update via string of the form `,` however the order created/updated webhook passes it as a string delimited by `, `.

So a mutation:

mutation orderUpdate($input: OrderInput!) {
  orderUpdate(input: $input) {
    order {
      id,
      tags,
    }
    userErrors {
      field
      message
    }
  }
}
{
  "input": {
    "id": "gid://shopify/Order/3222829039791",
    "tags": "asdf,bsdf,gsdf"
  }
}

Gives  a resulting webhook call of:

 "tags": "asdf, bsdf, gsdf",

I presume this means I just need to split on `,` and strip the resulting string?

You are correct. Tags are stored as a String, comma-delimited. So when you read them, you split into an array and when you write them you join with a comma.

@HunkyBill - the root of the question is more how spaces are handled. It looks like shopify does a trim internally.

That is if I invoke the orderUpdate graphql with the string "asdf,  two_spaces" the resulting tags are "asdf", "two_spaces" it strips the leading characters from the second tag. This is totally fine - just want to make sure this is expected and not going to change

makes sense. use strip. I see this kind of thing all the time with webhook data. lots and lots of crazy... inject emoji and other weird characters... makes for fun times.
