Get All Products, Orders, Categories Details Programmatically in Magento 2

Hello Magento Folks,

Basically, when it comes to Magento 2 then the developer can call API and can get all products effortlessly. Many REST calls return many parameters, And parsing via this data many times becomes complicated. For solving these errors a query parameter-based syntax for REST requests is given, which will respond partially. Also, check our previous article where I have illustrated 

How to Get All Products, Orders, Categories Details Programmatically in Magento 2:

Get All Products

Only the SKU, name, and price parameters for product items whose color attribute includes the value 4 are returned by the following query.

GET https://www.yourdomain.com/rest/V1/products/?searchCriteria[filter_groups][0][filters][0][field]=color&searchCriteria[filter_groups][0][filters][0][value]=4&searchCriteria[filter_groups][0][filters][0][condition_type]=finset&fields=items[sku,name,price]

{
"items":
[
 {
  "sku":"Configurable Test-R",
  "name":"Configurable Test-R",
  "price":10
 },
 {
  "sku":"SimpleProduct",
  "name":"Simple Product",
  "price":49
  }
 ]
}

Get Products with Categories

GET https://www.yourdomain.com/rest/V1/products/SimpleProduct?fields=name,sku,visibility,extension_attributes[category_links,stock_item[item_id,qty]]

{
 "sku":"SimpleProduct",
 "name":"Simple Product",
 "visibility":4,
 "extension_attributes":
 {
  "category_links":
  [
   {
     "position":0,
     "category_id":"3"
   }
  ],
  "stock_item":
   {
     "item_id":5,
     "qty":100
   }
 }
}

The above example returns the following results:

• The SKU and name and visibility of the product
• The entire category_links object. This is defined in extension_attributes
• The stock_item object’s item_id and qty fields. These are also defined in extension_attributes

Get All Orders

GET https://www.yourdomain.com/rest/V1/orders/1?fields=billing_address,customer_firstname,customer_lastname

{
 "customer_firstname":"Magecomp",
 "customer_lastname":"Tester",
 "billing_address":
 {
   "address_type":"billing",
   "city":"Bhavnagar",
   "company":"Magecomp",
   "country_id":"IN",
   "email":"test.magecomp@gmail.com",
   "entity_id":2,
   "firstname":"Magecomp",
   "lastname":"Tester",
   "parent_id":1,
   "postcode":"364002",
   "region":"Gujarat",
   "region_code":"GJ",
   "region_id":544,
   "street":["Bhavnagar"],
   "telephone":"9376646229"
  }
}

Get Categories
