Headers

For some types of the REST API requests, you can retrieve an additional information like the total number of records, the number of affected records, etc. To do this, use the X-Include request header. The value of this header should contain keys separated by a semicolon (;).

The following example shows how to get the total number of accounts:

curl "http://orocrm.loc/index_dev.php/api/accounts?page=1&limit=2" -v --header="X-Include:totalCount" --header="X-WSSE:..."

The corresponding response:

< HTTP/1.1 200 OK
...
< X-Include-Total-Count: 67
...

Hint

To generate a WSSE header, run: php bin/console oro:wsse:generate-header YOUR_API_KEY.

Existing X-Include Keys

The following table describes all existing keys for X-Include header.

Request Type X-Include key Response Header Description
all noHateoas Removes all HATEOAS related links from the response.
get a list of entities totalCount X-Include-Total-Count Returns the total number of entities. It is calculated based on input filters.
delete a list of entities totalCount X-Include-Total-Count Returns the total number of entities. It is calculated based on input filters.
delete a list of entities deletedCount X-Include-Deleted-Count Returns the number of deleted entities

Add New X-Include Key

To add a custom key to the X-Include header:

  1. Create a processor to handle your key:

    <?php
    
    namespace Oro\Bundle\ApiBundle\Processor\DeleteList;
    
    use Oro\Component\ChainProcessor\ContextInterface;
    use Oro\Component\ChainProcessor\ProcessorInterface;
    use Oro\Bundle\ApiBundle\Processor\Context;
    
    /**
     * Calculates and sets the total number of deleted records to "X-Include-Deleted-Count" response header,
     * in case it was requested by "X-Include: deletedCount" request header.
     */
    class SetDeletedCountHeader implements ProcessorInterface
    {
        const RESPONSE_HEADER_NAME = 'X-Include-Deleted-Count';
        const REQUEST_HEADER_VALUE = 'deletedCount';
    
        /**
         * {@inheritdoc}
         */
        public function process(ContextInterface $context)
        {
            /** @var DeleteListContext $context */
    
            if ($context->getResponseHeaders()->has(self::RESPONSE_HEADER_NAME)) {
                // the deleted records count header is already set
                return;
            }
    
            $xInclude = $context->getRequestHeaders()->get(Context::INCLUDE_HEADER);
            if (empty($xInclude) || !in_array(self::REQUEST_HEADER_VALUE, $xInclude, true)) {
                // the deleted records count is not requested
                return;
            }
    
            $result = $context->getResult();
            if (null !== $result && is_array($result)) {
                $context->getResponseHeaders()->set(self::RESPONSE_HEADER_NAME, count($result));
            }
        }
    }
    
    oro_api.delete_list.set_deleted_count_header:
        class: Oro\Bundle\ApiBundle\Processor\DeleteList\SetDeletedCountHeader
        tags:
            - { name: oro.api.processor, action: delete_list, group: delete_data, priority: -10 }
    
  2. Create a processor to remove your response header when an error occurs:

<?php

namespace Oro\Bundle\ApiBundle\Processor\DeleteList;

use Oro\Component\ChainProcessor\ContextInterface;
use Oro\Component\ChainProcessor\ProcessorInterface;

/**
 * Removes the "X-Include-Deleted-Count" response header if any error occurs.
 */
class RemoveDeletedCountHeader implements ProcessorInterface
{
    /**
     * {@inheritdoc}
     */
    public function process(ContextInterface $context)
    {
        /** @var DeleteListContext $context */

        if ($context->hasErrors()
            && $context->getResponseHeaders()->has(SetDeletedCountHeader::RESPONSE_HEADER_NAME)
        ) {
            $context->getResponseHeaders()->remove(SetDeletedCountHeader::RESPONSE_HEADER_NAME);
        }
    }
}
oro_api.delete_list.remove_deleted_count_header:
    class: Oro\Bundle\ApiBundle\Processor\DeleteList\RemoveDeletedCountHeader
    tags:
        - { name: oro.api.processor, action: delete_list, group: normalize_result, priority: 100 }
