  title: Prismatic Create Customer with Refreshed Token
  summary: Refresh an access token then create a new customer tenant.
  description: >-
    Embedded integration providers onboard each of their end users as a
    Prismatic customer. This workflow first refreshes the JWT access token from a
    supplied refresh token, then runs the documented createCustomer GraphQL
    mutation with the new customer's name and externalId carried as GraphQL
    variables. Note: Prismatic is a GraphQL-over-HTTP API, so the create
    operation is sent through the single executeGraphQLQuery endpoint and the
    mutation body is taken from the specification's documented createCustomer
    example.
