# Test And Monitor Your APIs And Generate Client Libraries Automatically With Postman **Published:** 2026-10-31 **Author:** Kin Lane **Canonical:** https://apievangelist.com/2026/10/31/test-and-monitor-your-apis-and-generate-client-libraries-automatically-with-postman/ If your business connects to other companies, or lets partners and customers connect to you, you probably depend on APIs, the connections that let one piece of software talk directly to another. When one breaks, the order does not sync, the invoice does not go out, and the first you hear of it is an angry email. You want to know before your customers do. [Postman](https://apis.io/providers/postman/) is where many teams build and test those connections, and it has an API of its own, so your systems or an AI assistant can set up the testing and monitoring and read the results. ## What Postman does Postman is an API platform. Postman says more than 35 million developers use it to design, build, test, document, mock, monitor and govern APIs. The everyday unit of work is the collection, a saved set of requests to an API, often with tests attached that check the answers are right. Around that sit workspaces for teams, mock servers (stand-ins that imitate an API before the real one is ready), monitors, a visual builder called Flows, an AI Agent Builder and an MCP server, the connector standard AI assistants use to call tools. More on the [Postman website](https://www.postman.com/). ## What you can get done ### Check your important connections on a schedule [Observability Management](https://apis.io/capabilities/observability-management/) is about seeing the health of your systems as they run. In Postman, a monitor runs a collection on a schedule, so a failure can get noticed at any hour. Setting these up through software means each new integration can get a monitor when it goes live, not after its first outage. - `GET /monitors` lists your scheduled monitors. - `POST /monitors` schedules a collection to run on a recurring monitor. - `PUT /monitors/{monitorId}` changes how a monitor is set up, including how often it runs. - `POST /monitors/{monitorId}/run` runs a monitor immediately. - `DELETE /monitors/{monitorId}` removes a monitor. ### Find out what failed, and when [Software Quality Engineering](https://apis.io/capabilities/software-quality-engineering/) keeps the record of your test runs. This is what you want when someone asks whether a connection was working last Tuesday, or whether a release broke something. - `GET /collections/{collectionId}/runs` lists the past runs of a collection. - `GET /collections/{collectionId}/runs/{runId}` shows which requests and tests failed in one run. ### Make it easy for others to connect to you [SDK & Client Library Management](https://apis.io/capabilities/sdk-client-library-management/) matters if you offer an API to customers or partners. An SDK, or client library, is a ready-made package that saves a programmer from writing the connection by hand. Generating them from what you already have makes it easier for people to start working with you. - `POST /sdks` generates an SDK from a collection or specification. - `GET /sdks/{sdkId}` shows an SDK and its build status. - `GET /sdks/{sdkId}/downloads` provides a download link. - `GET /sdks` lists the SDKs in a workspace. ### Keep track of the APIs you have [Public API Lifecycle Management](https://apis.io/capabilities/public-api-lifecycle-management/) is the record keeping. A schema is the formal description of what an API does. Keeping them in one place means your team is not guessing which version is current. - `GET /apis` lists the APIs in a workspace. - `POST /apis` creates a new API. - `GET /apis/{apiId}` shows the details of one API. - `POST /apis/{apiId}/schemas` attaches a schema to an API. ### Review changes and pull your invoices [Software Construction Management](https://apis.io/capabilities/software-construction-management/) covers review, so a change gets a second look before it is merged in. `GET /pull-requests/{pullRequestId}` shows who reviewed a change and `POST /pull-requests/{pullRequestId}/tasks` approves, declines or merges it. [Invoicing & Statement Management](https://apis.io/capabilities/invoicing-statement-management/) is a small one that your bookkeeper may appreciate: `GET /accounts/{accountId}/invoices` lists the invoices on your billing account. ## Workflows that put it together A workflow is a recipe of several calls in order that finishes a real job. APIs.io catalogs 21 for Postman, including: - [Stand Up an API Testing Pipeline](https://apis.io/arazzos/postman/postman-api-testing-pipeline-workflow/) builds a workspace, collection and environment, then monitors and runs the collection. - [Create and Run a Monitor](https://apis.io/arazzos/postman/postman-create-and-run-monitor-workflow/) schedules a monitor for a collection, runs it and reads the result. - [Bootstrap a Workspace](https://apis.io/arazzos/postman/postman-bootstrap-workspace-workflow/) creates a workspace and seeds it with a collection and an environment. - [Create an API with a Schema](https://apis.io/arazzos/postman/postman-create-api-with-schema-workflow/) creates an API, adds a version and attaches its description. - [Create a Mock Server from a Collection](https://apis.io/arazzos/postman/postman-create-mock-from-collection-workflow/) stands up a stand-in API from a collection. ## Ask for it in plain language Our conversational overlay for Postman maps everyday questions to the operation that answers them, so an AI assistant knows which call to make. These are the kinds of things you can ask: - "How do I schedule a collection to run on a recurring monitor?" - "Can I trigger a monitor run on demand instead of waiting for its schedule?" - "Can I see only the failed runs of a collection, or runs from a specific source?" - "How do I generate a TypeScript client library from my collection?" - "Which APIs exist in my Postman workspace?" - "Which invoices are on my billing account?" You can browse one in the [Postman Analytics phrasing overlay](https://apis.io/overlays/postman/postman-analytics-api-phrasing-overlay/). ## Getting started Postman is freemium with self-serve signup, and you call its hosted service. Start with the [Postman API documentation](https://www.postman.com/postman/postman-public-workspace/documentation/i2uqzpp/postman-api), the [authentication guide](https://learning.postman.com/docs/developer/postman-api/authentication/) and the page on [Flows](https://www.postman.com/product/flows/). On APIs.io, see the [Postman profile](https://apis.io/providers/postman/), the [Collections API](https://apis.io/apis/postman/collections-api/), the [Monitors API](https://apis.io/apis/postman/monitors-api/) and the [Workspaces API](https://apis.io/apis/postman/workspaces-api/). Name the one connection your business could least afford to lose, and ask your team to put a monitor on it this week.
