Client for Dokobit Gateway API

Dokobit Gateway PHP Client

, _(*1)

This library makes it easier to integrate Dokobit Gateway API in PHP applications by wrapping all of the Gateway API calls and responses in PHP objects., _(*2)

How to start?

1. Instantiate a client object:, _(*3)

   use Dokobit\Gateway\Client;
   
   // <...>
   $client = Client::create([
       'apiKey' => 'xxxxxx',
       'sandbox' => true,
   ]);
   

   If you want to log requests, just pass a PSR-3 LoggerInterface compatible logger (such as a Monolog instance) as the second parameter to the create() method, like this:, _(*4)

   use Dokobit\Gateway\Client;
   use Monolog\Handler\StreamHandler;
   use Monolog\Logger;
   
   // <...>
   $log = new Logger('requests');
   $log->pushHandler(new StreamHandler(__DIR__ . '/path/to/info.log', Logger::INFO));
   
   $client = Client::create([
       'apiKey' => 'xxxxxx',
       'sandbox' => true,
   ], $log);
   

2. Use the client instantiated above to make the desired API calls. To do that, instantiate a respective request object and pass it to the get() method of the client. For example, to upload a file to Gateway:, _(*5)

   use Dokobit\Gateway\Query\File\Upload;
   
   // <...>
   $request = new Upload('/path/to/your/document.pdf');
   $result = $client->get($request);
   echo $result->getStatus(); // Request status
   echo $result->getToken(); // Uploaded file token
   

   The client performs an HTTP request and returns a result object, which has getters for all response fields. Should the request fail for any reason, an exception will be thrown, which should help you debug the issue., _(*6)

The request (query) and response (result) classes closely mirror the API calls, which are documented at https://gateway-sandbox.dokobit.com/api/doc., _(*7)

To make downloading of signed files more convenient, the Client class also provides the downloadFile() method. To download a signed file, just call this method like this:, _(*8)

$client->downloadFile($signedFileUrl, $downloadedFilePath);

Note: this method will append your access token to the URL automatically, so you can pass it the URLs you receive from the Gateway's postbacks in their verbatim form, without any changes. The same method can also be used to download arbitrary files from other locations, if necessary. Should you want to do that, just pass false as the third argument to avoid appending the access token, like this:, _(*9)

$client->downloadFile($signedFileUrl, $downloadedFilePath, false);

For further code usage examples, please check integration tests under tests/Integration., _(*10)

Debugging

To dig more into occured error use following methods:, _(*11)

echo (string) $exception->getMessage()
echo (string) $exception->getPrevious()->getResponse()
var_dump( $exception->getResponseData() )

These methods are available on all exception classes except UnexpectedError and QueryValidator., _(*12)
