This section contains any information regarding the API methods made available by InPost used to communicate between the Merchant and InPost Pay.

On this page:

InPost Pay API

Production environment

 address: https://api.inpost.pl

Sandbox environment

Test environment address: https://sandbox-api.inpost.pl

List of endpoints

The table below presents a list of endpoints issued by the InPost Pay app, used for communicating between the Merchant and the InPost Pay app.

Widget 2.0 - the column contains a list of methods required to implement Widget 2.0 (Widget 2.0 [ENG])

Widget 1.0 - the column contains a list of methods required to implement Widget 1.0 (Widget 1.0 (old version) [ENG]), which is replaced by Widget 2.0. Recommended implementation is Widget 2.0 (Widget 2.0 [ENG]).

Example implementation in PHP

• We create an interface for the website of a customer, which will be responsible for Merchant-> InPost- InPost Pay (Basket App) communication.

  <?php declare(strict_types=1); namespace Iteo\InpostPayClient\Client; use Iteo\InpostPayClient\SDK\Basket\BasketApp\Basket; use Iteo\InpostPayClient\SDK\Basket\Binding\BindingBasket; use Iteo\InpostPayClient\SDK\Basket\Binding\QrCode\QrCodeData; use Iteo\InpostPayClient\SDK\Basket\Binding\Request\BasketApp\BasketBindingRequest; use Iteo\InpostPayClient\SDK\Basket\Response\BasketsResponse; use Iteo\InpostPayClient\SDK\Basket\Response\InpostBasketId; use Iteo\InpostPayClient\SDK\Core\Exceptions\InpostPayEndpointException; use Iteo\InpostPayClient\SDK\Core\Exceptions\InpostPayPostBasketBindingException; use Iteo\InpostPayClient\SDK\Core\Exceptions\InpostPayPostOrderEventException; use Iteo\InpostPayClient\SDK\Order\Request\BasketApp\OrderEventRequest; use Iteo\InpostPayClient\SDK\Order\Response\BasketApp\OrdersResponse; use Iteo\InpostPayClient\SDK\SignatureVerification\SigningKeys\SigningKeysResponse; use Iteo\InpostPayClient\SDK\SignatureVerification\SigningVersionKey\SigningKeyResponse; /** * Client interface used for communication between Merchant and InPost Pay application. */ interface InpostPayClientInterface { /** * This method verify if basket is connected with InPost app. * * @param string $basketId ID basket assigned by merchant * @param string|null $browserId Browser ID from cookie * * @return BindingBasket Object with information about whether the browser is trusted * and whether the basket is linked * * @throws InpostPayEndpointException */ public function getBasketBinding(string $basketId, ?string $browserId): BindingBasket; /** * This method connect basket with InPost app. * * @param string $basketId ID basket assigned by merchant * @param BasketBindingRequest $requestBody Request data, needed for binding basket * * @return ?QrCodeData Object with data for QR Code when successful binding with QR Code or null * when successful binding with phone number * * @throws InpostPayPostBasketBindingException|InpostPayEndpointException */ public function postBasketBinding(string $basketId, BasketBindingRequest $requestBody): ?QrCodeData; /** * This method desynchronize basket with Inpost Pay mobile app. * * @param string $basketId ID basket assigned by merchant * @param ?bool $ifBasketRealized Information about the fact that the basket will be deleted because * it has been realized * * @throws InpostPayEndpointException */ public function deleteBasketBinding(string $basketId, ?bool $ifBasketRealized): void; /** * This method updates or creates a basket e.g. change products quantity, delivery type etc. * * @param string $basketId ID basket assigned by merchant * @param Basket $basket All Basket data * * @return InpostBasketId Object with basket ID created from Inpost mobile app * * @throws InpostPayEndpointException */ public function putBasket(string $basketId, Basket $basket): InpostBasketId; /** * This method update order. * * @param string $orderId ID order assigned by merchant * @param OrderEventRequest $orderEventRequest Information about order event, that will change order status * * @throws InpostPayPostOrderEventException|InpostPayEndpointException */ public function postOrderEvent(string $orderId, OrderEventRequest $orderEventRequest): void; /** * This method deletes binded browser from Inpost Pay mobile app. * * @param string $browserId ID browser from cookie * * @throws InpostPayEndpointException */ public function deleteBrowserBinding(string $browserId): void; /** * This method get baskets list for merchant. * * @param ?int $pageIndex Information about page index of merchant baskets list * @param ?int $pageSize Information about page size of merchant baskets list page * * @return BasketsResponse Object containing list of baskets for merchant for strict page index * * @throws InpostPayEndpointException */ public function getBaskets(?int $pageIndex, ?int $pageSize): BasketsResponse; /** * This method get orders list for merchant. * * @param ?int $pageIndex Information about page index of merchant orders list * @param ?int $pageSize Information about page size of merchant orders list page * * @return OrdersResponse Object containing list of orders for merchant for strict page index * * @throws InpostPayEndpointException */ public function getOrders(?int $pageIndex, ?int $pageSize): OrdersResponse; /** * This method get public signing keys. * * @return SigningKeysResponse Object containing list of public signing keys * * @throws InpostPayEndpointException */ public function getSigningKeys(): SigningKeysResponse; /** * This method get public signing key for version. * * @param string $version Version of signing-key * * @return SigningKeyResponse Object containing public signing key * * @throws InpostPayEndpointException */ public function getSigningKey(string $version): SigningKeyResponse; }

• We create an url interface for the creator, which will be responsible for obtaining the right url address to InPostPay's API.

  <?php declare(strict_types=1); namespace Iteo\InpostPayClient\Client; /** * Interface used for creating url for communication with Inpost Pay. */ interface InpostPayURLCreatorInterface { /** * Method that return url for Inpost Pay. * * @return InpostPayURL url for Inpost Pay */ public function create(): InpostPayURL; }

• We create an implementation of the creator's url service for the Sandbox environment.

  <?php declare(strict_types=1); namespace Iteo\InpostPayClient\Client; /** * PHP URL Creator Service implementation used for creating url to Sandbox InpostPay. */ final class SandboxInPostPayURLCreator implements InpostPayURLCreatorInterface { /** * {@inheritdoc} */ public function create(): InpostPayURL { return new InpostPayURL('https://sandbox-api.inpost.pl/v1/izi/'); } }

• We create an implementation of the creator's url service for the Production environment.

• We create an implementation of the customer's website, by using a PSR client for REST communication, and the creator's url interface implemented in advance, in order to obtain the url to InpostPay's API, and the interface of the bearer's service in order to obtain an access token. For the Client to be fully functional, it is necessary to implement the functions described in the interface, responsible for the particular endpoints in the List of Endpoints.
