# Collection Runner | Postman API Platform

> Collection Runner now runs and automates API workflows that include GraphQL, gRPC, and HTTP requests.

## Collection Runner

Validate every endpoint at scale with data-driven testing.

[Read Docs](https://learning.postman.com/docs/getting-started/basics/using-api-client/)

---

## Execute, iterate, and validate APIs at the speed you ship

### Run any workflow

From simple requests to multi-step scenarios, Collection Runner provides end-to-end execution. No more testing endpoints one by one.

### Automate runs anywhere

Trigger runs manually, on a schedule, from the CLI, or in CI/CD so your APIs are tested before issues reach production.

### Validate in every environment

Keep tests consistent by swapping environments, not rewriting requests. Catch environment-specific issues before they reach users.

---

## Generate test coverage across your entire collection using prompts

Postman AI analyzes your collection and writes test scripts for every endpoint so you get comprehensive validation in minutes.

---

*CAPABILITIES*

### Run your entire test suite with a single click

Collection Runner executes every request in a collection with scripts, data files, and environment variables so you validate entire workflows in one run.

### Run complex workflows with ease

Test full collections that mirror real-world usage. From simple chains to multi-step workflows, Collection Runner keeps requests in order, giving you confidence that your API works from start to finish.

### Perform data-driven testing at scale

Upload CSV or JSON files to run workflows against hundreds of inputs. Quickly uncover edge cases, validate performance, and strengthen API reliability without extra setup.

### Simulate real-world load with performance tests

Test traffic with virtual users, track key metrics in real time, and spot bottlenecks before they reach production.

### Custom iterations

Set iteration counts and delays between requests to match your specific testing scenario.

### Run order control

Execute requests in sequence or use the setNextRequest function to build conditional test flows.

### Exportable results

Share run results with your team or export them for analysis and compliance reporting.

## Broken collaboration leads to broken APIs.

Ninety-three percent of API teams still face collaboration blockers. The 2025 State of the API report reveals how you can unlock the productivity gains that API-first promises, but scattered tooling prevents.
