.openapi-generator-ignore

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md

+The Order Management API is used for handling an order after the customer has completed the purchase. It is used for all actions you need to manage your orders. Examples being: updating, capturing, reading and refunding an order.
+
+Read more on the [Order management](https://docs.klarna.com/order-management/) process.
+
+
+## Installation & Usage
+
+### Requirements
+
+PHP 7.4 and later.
+Should also work with PHP 8.0.
+
+### Composer
+
+To install the bindings via [Composer](https://getcomposer.org/), add the following to `composer.json`:
+
+```json
+{
+  "repositories": [
+    {
+      "type": "vcs",
+      "url": "https://github.com/GIT_USER_ID/GIT_REPO_ID.git"
+    }
+  ],
+  "require": {
+    "GIT_USER_ID/GIT_REPO_ID": "*@dev"
+  }
+}
+```
+
+Then run `composer install`
+
+### Manual Installation
+
+Download the files and include `autoload.php`:
+
+```php
+<?php
+require_once('/path/to/OpenAPIClient-php/vendor/autoload.php');
+```
+
+## Getting Started
+
+Please follow the [installation procedure](#installation--usage) and then run the following:
+
+```php
+<?php
+require_once(__DIR__ . '/vendor/autoload.php');
+
+
+
+// Configure HTTP basic authorization: basicAuth
+$config = OpenAPI\Client\Configuration::getDefaultConfiguration()
+              ->setUsername('YOUR_USERNAME')
+              ->setPassword('YOUR_PASSWORD');
+
+
+$apiInstance = new OpenAPI\Client\Api\CapturesApi(
+    // If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.
+    // This is optional, `GuzzleHttp\Client` will be used as default.
+    new GuzzleHttp\Client(),
+    $config
+);
+$order_id = 'order_id_example'; // string | Order id
+$capture_id = 'capture_id_example'; // string | Capture id
+$update_shipping_info = new \OpenAPI\Client\Model\UpdateShippingInfo(); // \OpenAPI\Client\Model\UpdateShippingInfo
+$klarna_idempotency_key = 'klarna_idempotency_key_example'; // string | This header will guarantee the idempotency of the operation. The key should be unique and is recommended to be a UUID version 4. Retries of requests are safe to be applied in case of errors such as network errors, socket errors and timeouts. Input values of the operation are disregarded when evaluating the idempotency of the operation, only the key matters.
+
+try {
+    $apiInstance->appendShippingInfo($order_id, $capture_id, $update_shipping_info, $klarna_idempotency_key);
+} catch (Exception $e) {
+    echo 'Exception when calling CapturesApi->appendShippingInfo: ', $e->getMessage(), PHP_EOL;
