PHP SDK

The recommended way to interact with the Container API in PHP connectors is the official SDK. It wraps all HTTP endpoints into a typed ContainerApiInterface.

Installation

composer require productsupcom/container-api-client

The package is hosted on GitHub. Add the repository to your composer.json if you haven't already:

"repositories": [
    { "type": "vcs", "url": "https://github.com/productsupcom/container-api-client" }
]

Setup with Symfony

Wire the Container API client using factory classes and Symfony's DI container.

Factory classes — create these to instantiate the Container API client:

src/ContainerApi/ContainerApiClientFactory.php

<?php

namespace App\ContainerApi;

use GuzzleHttp\Client;

class ContainerApiClientFactory
{
    public static function create(): Client
    {
        return new Client(['base_uri' => 'http://cde-container-api']);
    }
}

src/ContainerApi/ContainerApiFactory.php

<?php

namespace App\ContainerApi;

use GuzzleHttp\Client;
use Productsup\CDE\ContainerApi\ContainerApi;

class ContainerApiFactory
{
    public static function create(Client $client): ContainerApi
    {
        return new ContainerApi($client);
    }
}

Service definitions — register the factories in a config file:

config/packages/container_api.yaml

services:
    container.api.client:
        class: GuzzleHttp\Client
        factory: ['App\ContainerApi\ContainerApiClientFactory', 'create']

    container.api:
        class: Productsup\CDE\ContainerApi\ContainerApi
        factory: ['App\ContainerApi\ContainerApiFactory', 'create']
        arguments:
            - '@container.api.client'

DI binding — bind the interface so it can be injected anywhere:

config/services.yaml

services:
    _defaults:
        autowire: true
        autoconfigure: true
        bind:
            Productsup\CDE\ContainerApi\ContainerApiInterface $containerApi: '@container.api'

Now you can inject ContainerApiInterface into any service:

public function __construct(
    private ContainerApiInterface $containerApi,
) {}

Key methods

Writing output (data source connectors)

Method	Description
`appendToOutputFile(array $item)`	Write a single product
`appendManyToOutputFile(array $items)`	Write a batch of products (auto-chunks large batches)
`streamToOutput(\Generator $generator)`	Stream products from a generator — memory-efficient for large datasets

Reading input (export connectors)

Method	Description
`yieldFromInputFile()`	Iterate all products one by one
`yieldBatchFromInputFile(int $size)`	Iterate products in batches
`countItemsFromInputFile()`	Get total item count

Reading delta input (export-delta connectors)

Method	Description
`yieldFromNewFile()`	Products added since last run
`yieldFromModifiedFile()`	Products changed since last run
`yieldFromUnchangedFile()`	Products with no changes
`yieldFromDeletedFile()`	Products removed since last run

Batch and count variants are also available: yieldBatchFromNewFile(int $size), countItemsFromNewFile(), etc.

Writing feedback (export connectors)

Method	Description
`appendToFeedbackFile(array $item)`	Write a single feedback entry
`appendManyToFeedbackFile(array $items)`	Write a batch of feedback entries

Logging

Method	Description
`info(string $message)`	Log an info message
`warning(string $message)`	Log a warning
`error(string $message)`	Log an error
`debug(string $message)`	Log a debug message

Metadata

Method	Description
`showHeaders(string $type)`	Get column names of an input file
`countItemsFromInputFile()`	Get item count
