Postman # Postman specialists for your dedicated team. Postman is an API development and testing platform: request collections, environment variables, scripted assertions, mock servers and contract documentation, with collections runnable in CI through its command-line runner. Our Postman testers turn loose API requests into a regression suite that runs on every commit. A broken endpoint is caught before your customers' integrations find it. ## When API testing in Postman needs an owner. Your team almost certainly has Postman collections already. They live in one developer's workspace, half the requests fail because the tokens expired, and they were last correct two releases ago. The need shows when a partner reports a broken endpoint those collections should have caught. It grows with the API's audience. Once mobile apps, partner integrations or paying API customers depend on your endpoints, a renamed field is an outage for somebody else. Contract checks on every build are cheap insurance. Microservices raise the stakes again. With twenty services calling each other, UI tests are too slow and too vague to say which service broke. ## What our Postman testers build into your pipeline. * Structured collections Organising requests by resource and workflow, with environments for local, staging and production and no hard-coded hosts or tokens. * Assertions Writing post-response scripts that check status codes, response times and the body against a JSON Schema. Negative cases for bad input and missing permissions go in as well. * Chained workflows Scripting flows such as sign up, log in, create an order and refund it, passing IDs and tokens between requests as variables. * Data-driven runs Feeding a collection from CSV or JSON files, so one run tries many input combinations. * CI runs Running collections with Newman or the Postman CLI in GitHub Actions, GitLab CI or Jenkins. A failed test fails the build, and the JUnit report shows which one. * Mocks and spec checks Generating collections from the OpenAPI file and comparing responses against it. Mock servers let frontend work begin before the endpoint exists. API tests are small daily work, and they only stay current when they have an owner. The QA engineers we assign take that role, full time on your product and inside your repositories and pipelines. They join as part of an [offshore QA team](https://azendo.co/services/dedicated-qa-and-testing-team/), managed from our offices in Bangkok and Chiang Mai. ## Where Postman test suites fall apart. Secrets in collections are the biggest risk. An API key typed into a request is synced to the cloud workspace and shared with everyone in it. Keys belong in local variable values, the Postman Vault or the CI secret store, and public workspaces need a regular check. Tests that only look for a 200 prove little. An endpoint can return the wrong customer's data with a perfect status code. Useful tests assert on the body, the schema and the permissions. Order dependence makes a suite fragile. A collection that only passes when run top to bottom on a fresh database will fail in CI for reasons that waste a morning. Each folder should create and remove its own data. ## Questions about Postman and API testing. * Is Postman enough, or do we need a code-based framework? Postman handles functional and contract checks well and is quick to learn. Large suites with heavy logic are easier to maintain in code, with REST Assured, pytest or Playwright's API testing. Teams that keep everything in Git sometimes prefer Bruno, which stores collections as plain files. * Can Postman do load testing? It has a basic performance runner for a quick check from one machine. For real load tests with distributed generators and detailed reports, use k6, JMeter or Gatling. * Do API testers need to write code? Enough JavaScript to write assertions, and enough SQL to check the data behind a response. They should also be able to read an OpenAPI file and a stack trace. When we recruit, logical thinking and mindset weigh as much as the technical side. ## Roles that use Postman * [Penetration Tester Cybersecurity](https://azendo.co/services/dedicated-cybersecurity-team/penetration-tester/) * [QA Engineer QA and test automation](https://azendo.co/services/dedicated-qa-and-testing-team/qa-engineer/) ## Service areas that use Postman * [Cybersecurity](https://azendo.co/services/dedicated-cybersecurity-team/) * [QA and test automation](https://azendo.co/services/dedicated-qa-and-testing-team/) Capacity is agreed across your whole team, with one monthly fee, not per skill. ## What it's used with * [REST, a skill in our teams](https://azendo.co/skills/rest/) * [GraphQL, a skill in our teams](https://azendo.co/skills/graphql/) * [API design, a skill in our teams](https://azendo.co/skills/api-design/) * [schema validation, a skill in our teams](https://azendo.co/skills/schema-validation/) * [OAuth, a skill in our teams](https://azendo.co/skills/oauth/) * [GitHub Actions, a skill in our teams](https://azendo.co/skills/github-actions/) * [Jenkins, a skill in our teams](https://azendo.co/skills/jenkins/) * [k6, a skill in our teams](https://azendo.co/skills/k6/) * [Playwright, a skill in our teams](https://azendo.co/skills/playwright/) * [Burp Suite, a skill in our teams](https://azendo.co/skills/burp-suite/) ## Related in qa and delivery tooling * [TestRail, a skill in our teams](https://azendo.co/skills/testrail/) * [Jest, a skill in our teams](https://azendo.co/skills/jest/) * [React Testing Library, a skill in our teams](https://azendo.co/skills/react-testing-library/) * [XCTest, a skill in our teams](https://azendo.co/skills/xctest/) * [Espresso, a skill in our teams](https://azendo.co/skills/espresso/) * [Detox, a skill in our teams](https://azendo.co/skills/detox/) * [Flutter Test, a skill in our teams](https://azendo.co/skills/flutter-test/) * [Cypress, a skill in our teams](https://azendo.co/skills/cypress/) ## Tell us what you need Postman for.
