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

Param	Query functions	Setter method	Type	Has validator?
DateTo	GetId, GetMigrationData	SetDateTo	String ('Y-m-d')	not yet
DateFrom	GetId, GetMigrationData	SetDateFrom	String ('Y-m-d')	not yet
MigrationDateTo	GetId, GetMigrationData	SetMigrationDateTo	String ('Y-m-d')	not yet
MigrationDateFrom	GetId, GetMigrationData	SetMigrationDateFrom	String ('Y-m-d')	not yet
UniqueId	GetMigrationData	SetUniqueId	Array of strings	not yet
NIP	GetMigrationData	SetNIP	Array of strings	yes
REGON	GetMigrationData	SetREGON	Array of strings	yes
NIP_SC	GetMigrationData	SetNIP_SC	Array of strings	yes
REGON_SC	GetMigrationData	SetREGON_SC	Array of strings	yes
Name	GetMigrationData	SetName	Array of strings	no
Province	GetMigrationData	SetProvince	Array of strings	no
County	GetMigrationData	SetCounty	Array of strings	no
Commune	GetMigrationData	SetCommune	Array of strings	no
City	GetMigrationData	SetCity	Array of strings	no
Street	GetMigrationData	SetStreet	Array of strings	no
Postcode	GetMigrationData	SetPostcode	Array of strings	yes
PKD	GetMigrationData	SetPKD	Array of strings	yes
Status	GetMigrationData	SetStatus	Array of integers within [1,2,3,4,9]	yes

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