SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps teams define external API and event contracts for a multi-tenant SaaS so integrations remain stable, tenant boundaries stay enforced, and breaking changes do not surprise partners.

Core Features & Use Cases

  • Tenant-safe API conventions: Derives tenant context from credentials, forbids client-supplied tenant IDs on data paths, and standardizes resource naming, pagination, errors, and idempotency.
  • Rate limiting and contract governance: Defines per-tenant and per-plan limits, plus versioning and deprecation rules with minimum notice, dual-run windows, and rollback planning.
  • Webhook and event design: Produces a versioned event envelope, thin payload conventions, tenant-scoped subscriptions, at-least-once delivery semantics, signing, replay protection, and redelivery behavior.
  • Use case: A platform team can use this Skill when launching partner APIs, adding webhooks, or changing response fields without breaking live integrations.

Quick Start

Ask the skill to design a tenant-safe public API and webhook contract for your product, including versioning, rate limits, and a migration plan.

FAQPage Schema
How do I design a tenant-safe public API for a multi-tenant SaaS?▼

Design tenant-safe public APIs by deriving tenant context directly from credentials, forbidding client-supplied tenant IDs on data paths, and standardizing resource naming, pagination, errors, and idempotent mutations. This approach maintains strict tenant boundaries and external integration stability.

What's the best way to version webhook event envelopes and handle delivery?▼

The best way to version webhook event envelopes is to use thin payload conventions with tenant-scoped subscriptions, signed at-least-once delivery semantics, and built-in replay protection. This ensures reliable event delivery and protects against noisy-neighbor rate limiting issues.

How do I manage breaking contract changes in partner integrations without breaking live systems?▼

Manage breaking contract changes by applying versioning and deprecation rules that enforce minimum notice, dual-run windows, and rollback planning. This dual-run deprecation policy prevents surprising live partners and allows safe migration to new API responses.

Why should I forbid client-supplied tenant IDs in my multi-tenant API data paths?▼

Forbidding client-supplied tenant IDs in multi-tenant API data paths enforces strict tenant boundaries by relying solely on credential-derived tenant context. This prevents cross-tenant data leakage and ensures noisy-neighbor rate limiting applies accurately per tenant.

Can I enforce per-plan and per-tenant rate limiting on external event feeds?▼

Yes, you can enforce per-tenant and per-plan rate limiting on external event feeds and public APIs. This contract governance limits noisy-neighbor effects and ensures fair resource distribution across different partner integration tiers.

How do I standardize idempotent mutations in a multi-tenant SaaS API?▼

Standardize idempotent mutations in a multi-tenant SaaS API by defining consistent resource naming, pagination, and error handling conventions alongside credential-derived tenant context. This prevents duplicate operations during network retries and maintains data integrity.
