Error is "message": "Internal Error. Details are available in Magento log file. Report ID: webapi-5dee36e254394".

When you run http://localhost:8888/magento/rest/V1/position/1

Need to get result from "position" column.

Api is for retrieving a column field by given user input.

 namespace SimpleMagento\Custom\Model;

use SimpleMagento\Custom\Api\InfoLinkInterface;
use SimpleMagento\Custom\Model\ResourceModel\Info\CollectionFactory; //Collection file
use SimpleMagento\Custom\Model\InfoFactory; //Implemented getter setter model

class InfoLink implements InfoLinkInterface
   private $collection;
   private $infoFactory;
   public function __construct(CollectionFactory $collection,InfoFactory $infoFactory)
 * @param int $id
 * @return \SimpleMagento\Custom\Api\Data\InfoInterface[]

public function getInfo($id)

    return $this->infoFactory->create()->getCollection()->addFieldToFilter('entity_id',$id)->getData();
    //return $this->infoFactory->create()->getData('position')->addFieldToFilter('entity_id',1);



webapi.xml is

<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<route url="/V1/position/:id" method="GET">
    <service class="SimpleMagento\Custom\Api\InfoLinkInterface" method="getInfo"/>
        <resource ref="anonymous" />

It seems like you added wrong model file class name in your di.xml file :

Change from :


To :


  • Thanks a lot for correction but not able to get, even after that. Code flow of developing API is corect, right? . To make it more simple I ll write SQL query , from which is I want to get result. **SELECT POISITION FROM NEW INFO WHERE ENTITY_ID=$ID ** Dec 10, 2019 at 4:10
  • You added addFieldToFilter with entity_id. I think it should be position. Dec 10, 2019 at 4:23
  • what you get data in getInfo function? Dec 10, 2019 at 4:24
  • just a string from position column Dec 10, 2019 at 4:27
  • If there will be unique record in your table. Then, you can use $record = $this->infoFactory->create()->getCollection()->addFieldToFilter('entity_id',$id)->getLastItem(); ................ and then you can return, $record->getPosition(); or $record['position']; Dec 10, 2019 at 4:30

Try to replace this line

return $this->infoFactory->create()->getCollection()->addFieldToFilter('entity_id',$id)->getData();

With this one

return $this->infoFactory->create()->getCollection()->addFieldToFilter('entity_id',array('eq', $id))->getFirstItem()->getPosition();

Follow this link for reference.

Hope this will help you!
