Postman Collection Manager

This skill manages Postman collections including import, export, and conversion operations.

Instructions

Importing Collections

  1. Import from OpenAPI

    • Use script: scripts/openapi-to-postman.sh <openapi.json> <output-collection.json>
    • Converts OpenAPI spec to Postman collection format

  2. Import from URL

    • Use script: scripts/import-from-url.sh <collection-url> <output.json>
    • Downloads and saves Postman collection

Exporting Collections

  1. Export Collection

    • Use script: scripts/export-collection.sh <collection.json> <format>
    • Formats: json, yaml, newman-ready

  2. Extract Endpoints

    • Use script: scripts/extract-endpoints.sh <collection.json>
    • Lists all endpoints in collection

Managing Collections

  1. Merge Collections

    • Use script: scripts/merge-collections.sh <collection1.json> <collection2.json> <output.json>
    • Combines multiple collections

  2. Filter Collection

    • Use script: scripts/filter-collection.sh <collection.json> <pattern> <output.json>
    • Filters requests by name or folder

Available Scripts

  • scripts/openapi-to-postman.sh - Convert OpenAPI to Postman
  • scripts/import-from-url.sh - Download collection from URL
  • scripts/export-collection.sh - Export in various formats
  • scripts/extract-endpoints.sh - List all endpoints
  • scripts/merge-collections.sh - Merge multiple collections
  • scripts/filter-collection.sh - Filter collection requests

Examples

Example 1: Import OpenAPI

# Convert OpenAPI spec to Postman collection
./scripts/openapi-to-postman.sh api-spec.json my-api-collection.json

Example 2: Manage Collections

# Extract all endpoints
./scripts/extract-endpoints.sh my-collection.json

# Filter to only GET requests
./scripts/filter-collection.sh my-collection.json "GET" filtered.json

Requirements

  • jq for JSON processing
  • curl for URL imports
  • openapi-to-postmanv2 npm package (for OpenAPI conversion)

Success Criteria

  • ✅ Collections imported successfully
  • ✅ OpenAPI conversions accurate
  • ✅ Exports valid and usable
  • ✅ Merged collections maintain structure
