It serves as the foundational layer for all multi-tenancy and subscription logic within the Altostrat SDX platform, enabling the secure separation of customer data and resources for SD-WAN, network automation, and agentic AI features. This API allows you to programmatically manage: - **Workspaces:** The top-level containers for all tenant resources, users, and billing configurations. - **Organizations:** Hierarchical entities used to model customer tenants or business units, track resource usage, and apply limits. - **Billing & Subscriptions:** The financial accounts and Stripe-powered subscriptions that govern access to Altostrat SDX features and resources. - **Members & Access:** The users and their specific roles (Owner, Admin, Viewer) within a workspace. Developers use this API to build the structural foundation and manage the billing lifecycle upon which all other Altostrat SDX automation and AI features operate. servers: - url: https://v1.api.altostrat.io description: Production API Server security: - bearerAuth: [] tags: - name: Workspaces description: Manage workspaces, the top-level containers for all resources. - name: Workspace Members description: Manage user access and roles within a workspace. - name: Organizations description: Manage hierarchical organizations for tenancy and resource segmentation. - name: Billing Accounts description: Manage financial accounts linked to Stripe for billing and subscriptions. - name: Subscriptions description: Manage product subscriptions powered by Stripe. - name: Invoices description: Retrieve invoice history and preview upcoming billing changes. - name: Payment Methods description: Manage customer payment methods for subscriptions. - name: Public description: Unauthenticated endpoints for retrieving public organization information. paths: /workspaces/{workspaceId}/billing-accounts/{billingAccountId}/subscriptions: post: tags: - Subscriptions summary: Create a subscription description: >- Creates a new Stripe subscription for a billing account.
