No access to email templates through api

GraphQL Admin API Troubleshooting
1

I’ve search for the whole Admin API to add capabilities to email template on behalf of my app.
But didn’t find anything I can do.

When examining admin.shopify.com/settings network requests I’ve found these graphql requests, tested them too but without success.

mutation EmailTemplateUpdate($input: EmailTemplateUpdateInput!) {
  emailTemplateUpdate(input: $input) {
    emailTemplate {
      id
      name
      title
      bodyHtml
      includeHtml
      hasDefaultBody
      hasDefaultTitle
      translatableResourceId
      __typename
    }
    userErrors {
      field
      message
      __typename
    }
    __typename
  }
}

And query

query NotificationSettingsIndex {
  customerNotificationSettings {
    id
    groupName
    groupDisplayName
    displayName
    description
    suppressible
    suppressed
    __typename
  }
}

Pretty sure that currently the Shopify GraphQL Admin API does not provide direct support for modifying notification email templates.

There may be something with the REST API that could be used but as that is legacy as of October 1, 2024, Shopify states:

All apps and integrations should be built with the GraphQL Admin API.

Currently I think the only suitable approach here would be to have the merchant provide access to their notification template code, you make the necessary modifications, and then save it and test it. Unfortunately that is obviously not an ideal approach but until there is a way to read and write the content via the GraphQL Admin API that’s the only one that is appropriate at the moment.

@Liam-Shopify any sort of extra information you could add here would be helpful. Specifically, whether or not there may be anything on the roadmap to enable such read and write down the road.
