Re: POST REST API Magento 2

Hello nidu,
There are a lot of example in Magento2 core module itself, you can check out there.
Here I am briefing basic steps to make a POST REST API in Magento 2.


step 1. create a webapi.xml , under etc/ directory
This file contains your routing information and methods which handle your implementation login. Here I am using token based authentication so I have used parameters customerId. You can get capture this id in your function implementation.


<routes xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Webapi:etc/webapi.xsd">
<route url="/V1/wishlist/add" method="POST">
<service class="Magento\Wishlist\Api\WishlistManagementInterface" method="addWishlistForCustomer"/>
<resource ref="self" />
<parameter name="customerId" force="true">%customer_id%</parameter>

step 2. create a di.xml if not exist in etc/.
This contains your interface and implementation class information. Example


 <preference for="\Magento\Wishlist\Api\WishlistManagementInterface" type="\Magento\Wishlist\Model\WishlistManagement" />

step3. create a file WishlistManagementInterface.php, the path must be same as shown in above code. An example of interface


 * Contributor company: iPragmatech solution Pvt Ltd.
 * Contributor Author : Manish Kumar
 * Date: 23/5/16
 * Time: 11:55 AM
namespace Magento\Wishlist\Api;

 * Interface WishlistManagementInterface
 * @api
interface WishlistManagementInterface

     * Return Added wishlist item.
     * @param int $customerId
     * @param int $productId
     * @return array
    public function addWishlistForCustomer($customerId,$productId);

step4. Create a file and class with the name WishlistManagement.php, the path must be same as the example of step2.

your implementation function goes here.
* Defines the implementaiton class of the WishlistManagementInterface
class WishlistManagement implements WishlistManagementInterface
public function addWishlistForCustomer($customerId, $productId)
if ($productId == null) {
throw new LocalizedException(__
('Invalid product, Please select a valid product'));

 Now you url :

and post parameter as



Try once if there is an issue let me know
