+# chirpstack-api
+
+ChirpStack gRPC API message and service wrappers for PHP.
+
+## Install
+
+With composer:
+
+```sh
+composer require chirpstack/chirpstack-api
+```
+
+## Usage
+
+All messages, services, constants, etc. are auto-generated from the ChirpStack protobuf definitions. The result is that
+this package structure matches that of the protobuf definitions.
+
+The protobuf definitions can be found here: https://github.com/chirpstack/chirpstack/tree/master/api/proto
+
+## Example
+
+```php
+<?php
+
+namespace Test;
+
+use Chirpstack\API\ApplicationServiceClient;
+use Chirpstack\API\ListApplicationsRequest;
+use Grpc\Channel;
+use Grpc\ChannelCredentials;
+
+require dirname(__FILE__) . '/vendor/autoload.php';
+
+function main() {
+    $channel = new Channel('url',  ['credentials' => ChannelCredentials::createInsecure()]);
+    $client = new ApplicationServiceClient('url', [], $channel);
+    $request = new ListApplicationsRequest();
+    $response = $client->List($request);
+    $data = $response->wait();
+    print_r($data);
+}
+
+main();
+```
