Custom metadata for a specific category of video?

Hi @adeelmiraj,

Below is a full example using the PHP client [can be obtained from https://github.com/kaltura/KalturaGeneratedAPIClientsPHP/archive/v13.20.0.tar.gz].
The objectId param should be the category ID, passed as a string [for PHP specifically, it doesn’t matter since it’s not a strongly typed language]. You didn’t mention your language of choice but the same should work with all our API clients.

<?php
require_once('/path/to/KalturaClient.php');

  $partnerId=;
  $partnerSecret='';
  $userId='';
  $config = new KalturaConfiguration($partnerId);
  $config->serviceUrl = 'https://www.kaltura.com';
  $client = new KalturaClient($config);
  $ks = $client->session->start(
    $partnerSecret,
    $userId,
    KalturaSessionType::ADMIN,
    $partnerId, 
    86400, 
    "disableentitlement");
  $client->setKS($ks);

  $objectType = KalturaMetadataObjectType::CATEGORY;

  // create a metadata profile
  $metadataPlugin = KalturaMetadataClientPlugin::get($client);
  $metadataProfile = new KalturaMetadataProfile();
  $metadataProfile->metadataObjectType = $objectType;
  
  $metadataProfile->createMode = "1";
  $metadataProfile->name = "z1";
  $metadataProfile->systemName = "myz1";
  $xsdData = "<xsd:schema xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><xsd:element name=\"metadata\"><xsd:complexType><xsd:sequence><xsd:element id=\"md_1FB651DF-20C9-BC17-60B9-6A7E93DBA671\" name=\"Myfield\" minOccurs=\"0\" maxOccurs=\"1\" type=\"textType\"><xsd:annotation><xsd:documentation></xsd:documentation><xsd:appinfo><label>myfield</label><key>myfield</key><searchable>true</searchable><timeControl>false</timeControl><description></description></xsd:appinfo></xsd:annotation></xsd:element></xsd:sequence></xsd:complexType></xsd:element><xsd:complexType name=\"textType\"><xsd:simpleContent><xsd:extension base=\"xsd:string\"></xsd:extension></xsd:simpleContent></xsd:complexType><xsd:complexType name=\"dateType\"><xsd:simpleContent><xsd:extension base=\"xsd:long\"></xsd:extension></xsd:simpleContent></xsd:complexType><xsd:complexType name=\"objectType\"><xsd:simpleContent><xsd:extension base=\"xsd:string\"></xsd:extension></xsd:simpleContent></xsd:complexType><xsd:simpleType name=\"listType\"><xsd:restriction base=\"xsd:string\"></xsd:restriction></xsd:simpleType></xsd:schema>";
  $viewsData = "";

  try {
    $result = $metadataPlugin->metadataProfile->add($metadataProfile, $xsdData, $viewsData);
    $metadataProfileId = $result->id;
    $objectId = ""; //category ID as string
    $xmlData = "<metadata><Myfield>LINUX RULES</Myfield></metadata>";

    try {
        // if created successfully, add metadata 
        $result = $metadataPlugin->metadata->add($metadataProfileId, $objectType, $objectId, $xmlData);
        var_dump($result);
    } catch (Exception $e) {
        echo $e->getMessage();
    }
  } catch (Exception $e) {
    echo $e->getMessage();
  }
  
  // retrieve metadata associated with a given category ID 
  $filter = new KalturaMetadataFilter();
  $filter->metadataObjectTypeEqual = KalturaMetadataObjectType::CATEGORY;
  $filter->objectIdEqual = ""; //category ID as string
  $pager = new KalturaFilterPager();

  try {
    $result = $metadataPlugin->metadata->listAction($filter, $pager);
    var_dump($result);
  } catch (Exception $e) {
    echo $e->getMessage();
  }

?>

You can learn about how to work with custom metadata by going through this tutorial:
https://developer.kaltura.com/workflows/Enrich_and_Organize_Metadata/Working_with_metadata;step=1

This tutorial explains how to work with ENTRY custom metadata objects/records whereas you’ll need to work with CATEGORY metadata but otherwise, the flow is similar and so are the service and action names [endpoints].

Each step also includes code samples.
