model: tenant-environment
note: >-
  ChannelEngine does not expose a fixed shared sandbox host or magic test
  values. Instead, each tenant can create separate environments (the paid plans
  include 1-5 environments) and test against its own subdomain. Sandbox testing
  is done by generating test orders and test marketplace returns inside a test
  environment, then exercising the acknowledge/ship/return flows. Never invent
  test identifiers — use the tenant's own environment.
environments:
  description: >-
    Plans include multiple isolated environments (Start 1, Grow 3, Scale 5) so
    integration testing runs against a non-production environment.
