[Mutations] My Account > Newsletter Subsciption

[misha-kotov]

As a Magento developer, I need to build a functional My Account experience for customers via GraphQL so that I can build basic ecommerce experiences for shoppers on the front-end using only GraphQL.

GraphQL needs to provide sufficient mutations (ways to create/update/delete data) for a developer to build out the storefront My Account experience for a shopper.

Use cases:

• A logged-in shopper can change their newsletter subscription preference from the My Account Page

Acceptance criteria:

• GraphQL provides a mutation through which the current logged-in shopper can subscribe or unsubscribe from any newsletter
• Authentication is handled through a session cookie
• A guest shopper cannot change the account information for any user
• Changes are covered with web API functional tests. See \Magento\GraphQl\Catalog\ProductViewTest::testQueryAllFieldsSimpleProduct as an example.

My Account area impacted:

• Newsletter Subscriptions tab
  

Note: functionality is closely related to issue #55 since they both modify the customer record
