Use this mutation when syncing information from an external data source into Shopify.

This mutation can be used to create a new customer, update an existing customer by id, or
upsert a customer by a unique key (email or phone).

To create a new customer omit the `identifier` argument.
To update an existing customer, include the `identifier` with the id of the customer to update.

To perform an 'upsert' by unique key (email or phone)
use the `identifier` argument to upsert a customer by a unique key (email or phone). If a customer
with the specified unique key exists, it will be updated. If not, a new customer will be created with
that unique key.
