MksDdn Collection for Postman helps developers quickly generate a Postman Collection (v2.1.0) or OpenAPI 3.0 documentation for WordPress REST API endpoints. The plugin automatically discovers and includes standard WordPress entities, custom post types, options pages, and individual pages. Generated collections include pre-configured requests with sample data and can be downloaded as JSON files for import into Postman. OpenAPI spec can be used with Swagger UI, Redoc, or frontend code generators.
The plugin provides comprehensive API testing capabilities with automatic generation of test data for form submissions, support for file uploads via multipart/form-data, and seamless integration with Advanced Custom Fields (ACF). Special handling is included for the mksddn-forms-handler plugin when active.
Features: 
– Basic REST endpoints: pages, posts, categories, tags, taxonomies, comments, users, settings 
– WooCommerce REST API (wc/v3): products, product categories, orders with full CRUD when WooCommerce is active 
– Search functionality: Posts, Pages, and All content types with customizable queries 
– Custom Post Types with full CRUD operations (List, Get by Slug/ID, Create, Update, Delete) 
– ACF/SCF fields: auto-included for all post types when ACF or Smart Custom Fields plugin is active 
– Special handling for Forms (mksddn-forms-handler integration) 
– Options endpoints: <code>/wp-json/custom/v1/options/...</code> 
– Individual pages by slug with ACF field support 
– Automatic test data generation for form submissions 
– Support for multipart/form-data for file uploads 
– Yoast SEO integration (automatic yoast_head_json inclusion)

– Service: Postman Collection Schema (schema.getpostman.com) 
– Purpose: Used to validate and structure the generated Postman Collection JSON according to the official Postman Collection v2.1.0 specification 
– Data sent: No data is sent to this service. The plugin only references the schema URL for validation purposes 
– When: The schema URL is included in the generated collection metadata for Postman to validate the collection structure 
– Terms of service: https://www.postman.com/legal/terms-of-use/
