Fortune 500 Logistics Provider — Customer Onboarding & Self-Service

Summary

Launched a productized developer onboarding and self-service model for partner integrations using Azure API Management as the front door and AKS for orchestration services. Partners self-enroll, receive subscription keys, test against Sandbox products, register callback URLs, and promote to Production with rate limits and observability—reducing time-to-first-quote and support tickets.

---

Problem

• Onboarding partners required manual steps (keys, environment URLs, callback registration), causing long lead times and back-and-forth with support.
• Lack of a consistent sandbox and contract-first APIs led to divergent implementations and avoidable defects at go-live.
• No self-service for key rotation, webhook updates, or quota visibility—driving operational load on platform teams.

---

Solution Mechanics

Primary pattern: API-led orchestration (Java + Spring Boot on AKS; Azure-first platform).

• Entry & Security

  • Azure API Management (APIM) as the front door with OAuth2 client credentials and subscription keys per product (Sandbox / Production).
  • APIM policies: validate-jwt, rate-limit, header enforcement (Idempotency-Key, Correlation-Id), and request/response validation.

• API Orchestration Layer (AKS / Spring Boot)

  • Onboarding Service: handles partner sign-up approval workflow, product assignment, and key issuance via APIM APIs.
  • Self-Service API: key rotation, callback URL registration, environment discovery (base URLs), and quota/usage queries.
  • Contract Registry: serves versioned OpenAPI (Sandbox/Prod), generates Postman collections, and publishes change logs.

• Data & Platform

  • Azure SQL: partner registry, product entitlements, audit trails, key metadata (no secrets).
  • Azure Service Bus: emits onboarding lifecycle events (approved, promoted, rotated) to CRM/support tools and notifies internal teams.
  • Azure Blob Storage: hosts downloadable artifacts (OpenAPI, collections, sample payloads).
  • App Insights / Azure Monitor: per-product latency/error dashboards; partner-scoped usage.

• Developer Experience

  • APIM Developer Portal branded pages: Quickstart (Sandbox credentials, base URLs), “Try-it” console, sample workflows, and callback test harness.
  • Promotion gates: contract tests + callback verification → auto-promote to Production product with rate limits and SLA.

Process Flow

1. Partner signs up in the APIM Developer Portal, requests access to the Sandbox product.
2. Onboarding Service reviews/auto-approves, assigns product, and issues subscription key; Sandbox base URLs and OpenAPI are provided.
3. Partner tests against Sandbox with idempotency headers and sample payloads; Try-it and Postman collections accelerate TTFQ.
4. Partner registers callback URL (Self-Service API); the platform sends a challenge request to verify ownership.
5. Automated contract tests run; upon passing, partner requests promotion to Production product.
6. Promotion policy applies rate limits, quotas, and environment base URLs; keys for Production are issued.
7. Usage & quotas visible in portal; partners can rotate keys, update callbacks, and review error/latency dashboards.
8. Lifecycle events (approve, promote, rotate) are published to Service Bus for CRM/support and internal visibility.

Outcomes

• Time-to-first-quote down via self-serve Sandbox, ready-made collections, and contract tests. (Verified in pilot rollouts.)
• Support load reduced: partners rotate keys, update callbacks, and view quotas without tickets. (Proxy from portal usage & ticket trends.)
• Lower go-live defects: contract-first APIs and callback verification catch issues pre-production. (Verified via reduced 4xx/5xx at cutover.)

---

Strategic Business Impact

• Faster partner activations (Modeled): productized onboarding compresses lead time from weeks to days.
• Steadier pipeline (Proxy): fewer cutover failures reduce revenue leakage during launches.
• Platform leverage (Proxy): repeatable products and artifacts enable parallel partner onboarding.

Method tags: Verified (measured in env/pilot), Modeled (cycle-time projections), Proxy (portal adoption, ticket reductions).

Role & Scope

Owned architecture for APIM products & policies, AKS orchestration services (Onboarding, Self-Service, Registry), SQL schema & audit, Service Bus events, Blob artifact hosting, and developer portal information architecture.

---

Key Decisions & Trade-offs

• Productized Sandbox/Production in APIM vs one-off keys: faster, consistent onboarding; requires policy discipline per product.
• Self-service over ticketed ops: lower support load; needs robust guardrails for abuse (rate limits, quotas).
• Contract-first with versioned OpenAPI: safer evolvability; requires consumer comms and deprecation windows.
• Callback verification gate: prevents broken webhooks in production; adds a small pre-go-live step.

---

Risks & Mitigations

• Key leakage/abuse → enforce rate limits, IP filters, and rotate keys; alert on anomalous usage.
• Spec drift → versioned contracts + change logs; deprecations with grace periods and portal banners.
• Portal sprawl → curate Quickstarts and auto-generate collections; archive old artifacts to Blob with clear versioning.
• Callback spoofing → challenge-response verification and signed callbacks in Production.

---

Suggested Metrics (run-time SLOs)

• TTFQ (median): sign-up → first successful Sandbox call.
• Promotion lead time: Sandbox pass → Production access.
• 4xx/5xx rate by partner/product; p95 latency by operation.
• Portal adoption: % partners using self-service (key rotation, callback updates).
• Quota incidents: rate-limit hits vs successful throughput; ticket volume trend.

Closing principle

Make the platform the product. Treat onboarding as a first-class product—contracts, sandboxes, keys, and self-serve—so integrations scale without scaling the support queue.
