Build and scale your private APIs
Postman makes internal APIs discoverable, reusable, and secure. With a central directory of workspaces and collections, teams onboard faster, avoid duplication, and scale private services with confidence.
Make private APIs easy to find and use
Private APIs keep your business running, but they often sprawl across repos, docs, and tools. Postman's Private API Network brings them all together in one place, so teams can find, reuse, and govern services without digging through docs or Slack.
One place for every internal API
The Private API Network is your organization's central hub where teams can discover, share, and govern internal APIs with confidence.
Centralized API hub
One place to find every internal API. No more hunting through Slack threads, docs, or repos.
Reusable services
No need to duplicate work. Reuse existing services and accelerate delivery across teams.
Built-in guardrails
Platform teams set access and approval rules once, so services stay consistent without slowing engineers down.
Faster onboarding
New engineers can immediately start forking examples, sending requests, and exploring trending APIs.
How teams adopt private APIs at every stage
Whether you're prototyping in a project, sharing across teams, or managing APIs company-wide, Postman makes it easy to publish, discover, and reuse internal services at every stage.
Single-team: every team gets a home base
Postman gives each team a hub workspace to manage specs, mocks, and tests in one place, so engineers move faster with less friction.
Cross-team: publish once, reuse everywhere
Discovery workspaces let teams publish well-documented APIs that others can fork and build on, reducing duplication and speeding up delivery.
Project-level: experiment freely
Flexible, temporary workspaces make it easy to prototype, demo, or integrate partners without disrupting your permanent API ecosystem.
Platform-wide: one trusted catalog
The Private API network ensures company-wide APIs are governed, trusted, and discoverable, which prevents costly duplication.
Postman's impact on how we build software at Toast has been huge. Not only has it saved time; it has enabled a massively distributed group of people to act as one team.”
