# API lifecycle management — Use case > Design, ship, version, deprecate, and retire APIs on one timeline. Apinizer turns the lifecycle into a system platform teams prefer and auditors trust. *Platform teams · Lifecycle · For platform teams* ## Design, ship, version, retire — without leaving the platform. From OpenAPI draft to production cutover, every API lives on one timeline. Platform teams hand engineers a clean lane and hand auditors a clean trail.

They have a wiki and a Slack channel. Specs land in Confluence. Deploys live in someone's terminal history. Versioning is a vibe. When the audit team asks who changed the rate limit on Wednesday at 14:32, no one can answer. Apinizer turns the lifecycle into a system — one engineers prefer and auditors trust. --- ## At a glance - **340** — APIs (managed on one platform) - **92** — legacy SOAPs (retired on schedule) - **3 days** — review cycle (down from 2 weeks) --- ## Capabilities ### Spec-first design OpenAPI, SOAP, gRPC, and async patterns drafted, reviewed, and approved in one place — the same place they ship from. ### One-click promotion Move a definition from dev to test to production without touching the runtime. Promotion is a button, not a meeting. ### Versioning side-by-side Run two versions of the same endpoint at the same time. Partners migrate at their own pace; you don't break anyone's Monday. ### Deprecation with hard cutoff Mark an endpoint deprecated, set the sunset date, broadcast it to consumers, and the gateway shuts the door when the clock hits zero. ### Audit at the persistence layer Every change — who, what, when, from which IP — written immutably. Auditor evidence is a query, not a forensic project. ### Programmatic apply APIops manifests with name-based references and idempotent applies. Engineers ship from the same Git they already use. --- ## Real-world examples ### Banking **Scenario:** A Tier-1 retail bank in Istanbul consolidates 340 APIs **Outcome:** 92 legacy SOAP endpoints retired on a published schedule. Spec reviews moved from Confluence to the gateway; deprecation notices reach partners 90 days before sunset. **Metric:** 92 endpoints retired ### Manufacturing **Scenario:** Munich automotive OEM standardizes spec-first across 14 plant teams **Outcome:** Plant integrations land as OpenAPI drafts in the platform first. Promotion to production needs a sign-off from quality + security — both wired into the gateway. ### E-commerce **Scenario:** Amsterdam marketplace replaces a wiki-driven process with one timeline **Outcome:** Pre-release reviews drop from two weeks to three days. Every version is queryable, side-by-side, with traffic counts and consumer breakdowns. **Metric:** Review 2w → 3d ### Public sector **Scenario:** Stockholm regional health agency promotes specs across three environments **Outcome:** Dev → test → prod in one command. The compliance officer signs the same manifest engineers pushed — no parallel paperwork. ### Logistics **Scenario:** Warsaw 3PL ships versions side-by-side for hundreds of partners **Outcome:** v2024-q1 and v2024-q3 served simultaneously. Partners migrate on their own clock; the gateway tracks who's still on v1 and reaches out programmatically. ### Insurance **Scenario:** Milan insurer enforces 130 endpoint sunsets on a published calendar **Outcome:** Deprecation headers reach consumers 90 days out; the gateway returns a clear 410 with migration instructions on cutover day. Audit thanked the platform team. **Metric:** 130 endpoints, 0 surprises ### Energy **Scenario:** Baku utility binds every spec change to a ticket ID **Outcome:** The audit trail joins specs to issues to deploys. The regulator's quarterly evidence packet is a single export, generated overnight. ### Telecom **Scenario:** Athens carrier ships API-as-code manifests via GitOps **Outcome:** Daily deploys without an after-hours call. Same manifests power dev, test, and prod — environments differ only in the variables, not the definitions. --- ## Four stages, one timeline, one source of truth. Each stage runs on the same platform — no exports, no parallel tooling, no hand-offs that lose history. - **01 · Design** — Draft the OpenAPI / SOAP / async contract in the platform. Reviewers approve in place; the spec is the source of truth. - **02 · Ship** — Promote to staging with one click — or one APIops apply. The gateway picks up the new definition without a restart. - **03 · Govern** — Add policies — auth, rate limits, transforms, versions — and watch real traffic in Analytics. Change anything; audit captures it. - **04 · Retire** — Mark deprecated, set a sunset date, broadcast headers to consumers. On cutover, the gateway closes the door — and the auditor has the receipt. --- ## Recommended modules - [API Designer](https://apinizer.com/products/api-designer) — Spec-first authoring for OpenAPI, SOAP, and async patterns — the place every API starts. - [API Gateway](https://apinizer.com/products/api-gateway) — The runtime that enforces every version, header, rate limit, and sunset date you ship. - [Analytics Engine](https://apinizer.com/products/analytics-engine) — Real-time evidence of what every version is doing — who's still on v1, who's drifted to v3. - [AI Gateway](https://apinizer.com/products/ai-gateway) — Same lifecycle for LLM and agent endpoints. AI is just another version of the API. --- ## Resources - [API lifecycle in Apinizer](https://docs.apinizer.com/en) — How the platform handles design, promotion, versioning, and deprecation end-to-end. - [Architecture overview](https://docs.apinizer.com/en/concepts/architecture) — Where the lifecycle lives on Kubernetes — Manager, Worker, and the audit plane. - [APIops manifests](https://apinizer.com/developers/apiops) — Git-driven applies with name-based references, idempotent semantics, and the same audit aspect as the UI. - [Changelog](https://docs.apinizer.com/en/release-notes/change-log) — Recent lifecycle features — deprecation headers, version selectors, audit exports. - [API Designer](https://apinizer.com/products/api-designer) — OpenAPI-first design with one-click proxy generation across protocols. - [Audit & compliance posture](https://apinizer.com/solutions/kvkk-gdpr-bddk-compliance) — How Apinizer maps to BDDK, KVKK, GDPR, and ISO 27001 evidence requirements. --- ## Related use cases - [APIops (CI/CD)](https://apinizer.com/solutions/apiops) — For developers - [OpenAPI-first design](https://apinizer.com/solutions/openapi-first) — For developers - [Three-tier permissions](https://apinizer.com/solutions/three-tier-permissions) — For platform teams - [Observability & audit](https://apinizer.com/solutions/observability-audit) — For platform teams --- ## Next step *Stop versioning APIs in a wiki* **One timeline.
