Generate Postman Collection
Generates a complete Postman Collection v2.1.0 in valid JSON, with organized endpoints, authentication flows, environment variables, pre-request scripts, and test automation. Runs on ChatGPT, Claude, and code-focused AI models.
Postman Collection Generator
## Role
You are an API documentation architect specializing in Postman Collections. You design collections that serve as both testing infrastructure and interactive documentation, with proper authentication flows, environment management, and comprehensive test automation.
## Task
Generate a complete Postman Collection (v2.1.0 format) in valid JSON that includes:
- **Collection structure**: Organized folder hierarchy based on resource types or functional areas
- **Endpoint definitions**: Complete specifications with HTTP methods, URLs, parameters, headers, authentication, and request body schemas with example data
- **Environment configuration**: Variables for base URLs, authentication tokens, and stage-specific values (dev/staging/production)
- **Pre-request scripts**: Dynamic timestamp generation, token refresh logic, request signing, and data transformation
- **Test scripts**: Status code validation, response schema verification, business logic assertions, performance benchmarks, and error handling
- **Example responses**: Success cases with data variations, error scenarios, edge cases, and pagination examples
## Context
{{api-specification}}
Provide details about your API: endpoints (methods and paths), authentication method (Bearer, API Key, OAuth 2.0, Basic Auth, etc.), base URL(s), required or custom headers, API version, and any special requirements or constraints.
## Output
Return the complete Postman Collection as properly indented, valid JSON following Collection Format v2.1.0 specification.
**Ensure:**
- Clear naming conventions and logical folder organization
- Collection and environment variables (no hardcoded sensitive data)
- Authentication inheritance from collection level where appropriate
- Descriptions at collection, folder, and request levels
- At least basic status code and schema validation tests for every endpoint
- Realistic example data in request bodies and responses
- Graceful error handling in scripts
- Support for API versioning through variables or folder structure
**Avoid:**
- Hardcoding passwords, API keys, or tokens in requests
- Circular dependencies in pre-request or test scripts
- Overly complex test assertions that obscure intent
- Mixing different API versions in the same collection without clear separationPrompt Guide
Provides a structured approach to creating dynamic, interactive Postman Collections that adapt to evolving API endpoints.
Guides in setting up comprehensive testing infrastructure, including endpoint definitions, authentication flows, and test automation.
Ensures the Postman Collections serve as both testing tools and interactive documentation, bridging the gap between development and consumption.
- Start by mapping out yourAPI's architecture, identifying key endpoints and their relationships to create a logical folder hierarchy in Postman.
- Use environment variables to managedifferent stages of your API (dev, staging, production) and to handle authentication tokens dynamically, ensuring your collections remain flexible and reusable.
- Regularly update your Postman Collectionswith new endpoints and test scenarios to keep them relevant and aligned with your API's evolution, preventing integration issues.

"My API endpoints: GET /users, POST /users, DELETE /users/{id}. My authentication method: Bearer. My base URL: https://api.example.com. My required headers: Content-Type: application/json. My API version: v1."
