Can I get a customer's tags in GraphQL so I can add and update them? What's the best practice?

Technical Q&A

Let’s say I have a customer who is tagged with “red” and I want to add a tag with “blue”. In this mutation, it will overwrite “red”.

mutation {
      customerUpdate(input: {
        id: "gid://shopify/Customer/5908902880321",
        tags: ["blue"]
    }) {
    customer {
      lastName
    }
    userErrors {
      field
      message
    }
  }
}

So, what is the best way to get all tags first? Should I query and then in node submit the mutation with all tags + the new ones if those tags don’t exist?

Hey!

You could query all the tags first.. But maybe you can do it with one query also with the tagsAdd mutation?
