Save metafields for customers

[Baam]

I have created a Customer metafield is 'Time'; please let me know how I can use the code to save a variable to that metafield

Hi Baam,

To save a variable to a Customer metafield with the key 'Time', you can use the customerUpdate mutation, it would look something like:

mutation UpdateCustomerMetafield {
  customerUpdate(input: {
    id: "gid://shopify/Customer/1234567890123", # Replace with the actual customer ID
    metafields: [
      {
        namespace: "custom_namespace", # Replace with your namespace
        key: "Time",
        value: "2023-10-03T15:18:59.106Z", # Replace with the value you want to save
        type: "date_time" # Ensure the type matches the value format
      }
    ]
  }) {
    customer {
      id
      metafields(first: 5) {
        edges {
          node {
            namespace
            key
            value
            type
          }
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}

In this example:

• Replace "gid://shopify/Customer/1234567890123" with the actual customer ID.
• Replace "custom_namespace" with the appropriate namespace for your metafield.
• Replace the value with the actual value you want to save to the metafield.
• Ensure the type matches the format of the value you are saving.
