Integration\n\n### Maven / Gradle\n\nThe fiskaly Java SDK is available via Maven.\n\n#### JRE (version 1.6+)\n\nAdd the following to your `build.gradle`:\n\n```groovy\ndependencies {\n    implementation 'com.fiskaly.sdk:fiskaly-sdk:1.2.200-jre'\n}\n```\n\nAdditionaly to the SDK, you'll also need the fiskaly client. Follow these steps to integrate it into your project:\n\n1. Go to [https://developer.fiskaly.com/downloads](https://developer.fiskaly.com/downloads)\n2. Download the appropriate client build for your platform\n3. Move the client into your project output directory or somewhere within the OS search path\n\n#### Android\n\nFirst of all, download the [fiskaly Client](https://developer.fiskaly.com/downloads) for android (e.g. `com.fiskaly.client-android-all-v1.2.200.aar`) and copy the Android Archive to `app/libs/`\n\nThen, add the following to your `app/build.gradle`:\n\n```groovy\ndependencies {\n    implementation 'com.fiskaly.sdk:fiskaly-sdk:1.2.200-android'\n    implementation files('libs/com.fiskaly.client-android-all-v1.2.200.aar')\n}\n```\n\n## Usage\n\n### Demo\n\n```java\npackage com.fiskaly.sdk.demo.jre;\n\nimport com.fiskaly.sdk.*;\n\npublic class Main {\n    public static void main(String[] args) throws Exception {\n        final String apiKey = System.getenv(\"FISKALY_API_KEY\");\n        final String apiSecret = System.getenv(\"FISKALY_API_SECRET\");\n        final FiskalyHttpClient client = new FiskalyHttpClient(apiKey, apiSecret, \"https://kassensichv.io/api/v1\");\n        final FiskalyHttpResponse response = client.request(\"GET\", \"/tss\");\n        System.out.println(response);\n    }\n}\n```\n\n## Proguard Configuration\n\n```\n-keep class com.sun.jna.* { *; }\n-keepclassmembers class * extends com.sun.jna.* { public *; }\n```\n\n### Client Configuration\n\nThe SDK is built on the [fiskaly Client](https://developer.fiskaly.com/en/docs/client-documentation) which can be [configured](https://developer.fiskaly.com/en/docs/client-documentation#configuration) through the SDK.\n\n## Related\n\n* [fiskaly.com](https://fiskaly.com)\n* [dashboard.fiskaly.com](https://dashboard.fiskaly.com)\n* [kassensichv.io](https://kassensichv.io)\n* [kassensichv.net](https://kassensichv.net)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffiskaly%2Ffiskaly-sdk-java","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffiskaly%2Ffiskaly-sdk-java","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffiskaly%2Ffiskaly-sdk-java/lists"}
