Currently we are able to create new users using Graphql in Storefront API. However, we would like to tag the customer and store additional information about the users during the account creation process.
Hence, can we please request for the ability to mutate customer metafields and customer tags from the storefront API. This avoid having to use the Admin API just to update information about the customers.
Afterall, the customer is already authenticated using Storefront API, there is no reason to limit to limit the ability to update their information after the authentication.
This would be of tremendous value and would enable Storefront API users to significantly expand the types of features that they can build for end-users.
The alternative is to build your own server and/or Shopify app that implements a customer version of customer tags.
