Requirements

• PHP 7.3 and above
• PHP's cURL support
• PHP's JSON support
• Any HTTP client compatible with PSR-18 (covered by the installation instructions).
• Any HTTP factories implementation compatible with PSR-17 (covered by the installation instructions).
• Any HTTP messages implementation compatible with PSR-7 (covered by the installation instructions).
• Other dependencies listed in the composer.json (covered by the installation instructions)

Installation

Follow those steps to install the library:

1. Download and install Composer package manager.
2. Install the library from the Packagist by executing this command:

During the installation you will see this message. Press 'y' when you do:

After that, you may see a message which will look like this:

Choose [a]lways by typing a and pressing Enter.

Note: You should choose 'y' and [a]lways if your application is using CI/CD pipeline because the interactive terminal is not available in that environment which will result in failure during the dependencies installation.

If you chose something else during the installation and API client doesn't work properly - please follow these instructions to fix the problem.

3. Include the autoloader if it's not included, or you didn't use Composer before.

Replace path/to/vendor/autoload.php with the correct path to Composer's autoload.php.

Note: API client uses php-http/curl-client and nyholm/psr7 as a PSR-18, PSR-17 and PSR-7 implementation. You can replace those implementations during installation by installing this library with the implementation of your choice, like this:

More information about that can be found in the documentation.

Usage

Firstly, you should initialize the Client. The easiest way to do this is to use the SimpleClientFactory:

The client is separated into several resource groups, all of which are accessible through the Client's public properties. You can call API methods from those groups like this:

For example, you can retrieve the customers list:

Or the orders list:

To handle errors you must use two types of exceptions:

• RetailCrm\Api\Interfaces\ClientExceptionInterface for the network or other runtime errors.
• RetailCrm\Api\Interfaces\ApiExceptionInterface for the errors from the API.

An example of error handling can be found in the next section of this document.

Each resource group is responsible for the corresponding API section. For example, costs resource group provide methods for costs manipulation and loyalty resource group allows interacting with loyalty programs, accounts, bonuses, etc.

Use annotations to determine which DTOs you need for sending the requests. If annotations are not provided by your IDE - you probably should configure them. It'll ease your work with this (and any other) library a lot.

More information about the usage including examples can be found in the documentation.

Examples

Listing orders:

Fetching a specific order by it's ID:

Creating a new customer:

Creating a task for the user with a specific email:

The error handling in the examples above is good enough for real production usage. You can safely assume that ApiExceptionInterface is an error from the API, and ClientExceptionInterface is a client error (e.g. network error or any runtime error, use HttpClientException to catch only PSR-18 client errors). However, you can implement more complex error handling if you want.

Also, both ApiExceptionInterface and ClientExceptionInterface implements __toString(). This means that you can just convert those exceptions to string and put the results into logs without any special treatment for the exception data.

More examples can be found in the documentation.

You can use a PSR-14 compatible event dispatcher to receive events from the client. See documentation for details.
