PHP CEIDG API library

We proudly present a PHP library to connect with CEIDG (Polish registry on businesses) API, using SOAP protocol.

Our library is capable of parsing querying result into well-formatted object or array of objects, validating inputted data (such as VAT number). Build atop the SOLID, DRY, and KISS principles, it provides a comprehensive tool to communicate with CEIDG API.

Please refer to the official API documentation, available at the CEIDG system website at https://datastore.ceidg.gov.pl (you should be logged in to view documentation files). Our library reflects their idea wholly.

Usage

Installation

As simple as it can be:

composer require sigrun/ceidg-api

Declaring API client

To declare API client, create new client class, with authorization token and (optionally) sandbox flag as arguments:

use CeidgApi\CeidgApi;

$authToken = 'secret';

// To connect with the production environment
$ceidgProductionApi = new CeidgApi($authToken);

// To connect with the sandbox environment
$ceidgSandboxApi = new CeidgApi($authToken, true);

Declaring requested function

CEIDG API provides two SOAP functions - GetId and GetMigrationData201901. The first returns only companies' unique IDs, whereas the second one - full data on the companies.

$getId = $ceidgProductionApi->getId();

$getMigrationData = $ceidgProductionApi->getMigrationData();
// or
$getMigrationData = $ceidgProductionApi->getMigrationData201901();

Setting query parameters with a simple chain of responsibility pattern

We've implemented a simple chain of responsibility pattern, enabling easy setting up querying params.

// To get IDs of all companies modified or created on August 5th, 2019
$result = $getId->setMigrationDateFrom('2019-08-05')->setMigrationDateTo('2019-08-05')->send();

// To get IDs of all companies having postcode '02-662'
$result = $getId->setPostcode('02-662')->send();

Parsing of response

You can demand on-the-fly parsing of the result. Depending on the number of retrieved entries, you will receive either a single object or an array of them. send() method has a $parse argument, default set to true.

An example (abbreviated) of parsed response looks as following:

{
  "IdentyfikatorWpisu": "ff83fff2fc2ab947f78fb6069f1767df",
  "DanePodstawowe": {
    "Imie": "Ryszard",
    "Nazwisko": "Petru",
    "NIP": "8991999655",
    "REGON": "147022306",
    "Firma": "Ryszard Petru Consulting"
  }
}

Single line of code

You can do everything mentioned above, within a single line of code:

$result = (new CeidgApi($authToken))->getId()->setMigrationDateFrom('2019-08-05')->setMigrationDateTo('2019-08-05')->send();

Available params

Available query params are compliant with those described in the official API documentation. A 'UniqueId' param can be set using the 'setUniqueId' method, a 'NIP' param - using the 'setNIP' method, etc.

Removing param from query

To remove a param from query params array, you can call a method with 'null' as its only argument, like 'SetUniqueId(null)'. There's no difference between method names starting with a capital letter or not.

GetMigrationData

When a SOAP request envelope is sent, all previously set params are cleared.
