Payvision PHP SDK

Codebase for Payvision PHP SDK

This is the official PHP SDK for Payvision payments platform ( It can be used to make use of the following features of the Payvision API:

  • Make payment requests
  • Make refund requests
  • Get transaction status updates


This package can be installed using Composer:

composer require payvision/payvision-sdk-php


Initialize the API

To initialize the API Connection, refer to the following code snippet:

use Payvision\SDK\Infrastructure\ApiConnection;

$apiConnection = new ApiConnection(
    'business ID',
    ApiConnection::URI_TEST,    // =URL to connect to, optional
    false                       // debug mode, see debugging

Debugging the API

The API uses the Guzzle HTTP Client. The debug-property is passed through to the Guzzle Client. See for more information about debugging.

Creating a payment request

The PHP SDK is a direct reflection of how the JSON structure of the requests and responses are typically built for the Payvision API.

For example, a typical payment request to the Payvision API would require a JSON body like this:

  "header" : {
    "businessId" : "{businessId}"
  "action" : "authorize",
  "body" : {
    "card" : {
      "holderName" : "John Doe",
      "number" : "4111111111111111",
      "expiryMonth" : "03",
      "expiryYear" : "2020"
    "transaction" : {
      "amount" : "1.00",
      "brandId" : "1010",
      "trackingCode" : "7F4BFD5D-55E4-4775-81F7-0784188876C7",
      "currencyCode" : "EUR"

To create this identical request using the PHP SDK, you can use one of the composite builders:

use Payvision\SDK\Domain\Payments\Service\Builder\Composite\Request\Object as RequestObjectBuilder;
use Payvision\SDK\Domain\Payments\ValueObject\Request\Object as RequestObject;

    ->setHolderName('John Doe')
$requestObject = $this->requestObjectBuilder->build();

At this point, you have a PHP representation of the JSON object that is to be sent to the API, but it is not yet the actual request. For example: we still need to know the URL where it needs to be sent to, and what kind of response we can expect from the API.

To do this we need to transform our payment request to an API request:

use Payvision\SDK\Application\Payments\Service\RequestBuilder;
$apiRequest = RequestBuilder::newPayment($requestObject);

Now we have an API Request that we can execute using our API Connection:

$apiResponse = $apiConnection->execute($apiRequest);

Handling the responses

The $apiResponse in the above example is an object of the type that is defined in the request. To know what kind of type this is, you can use $apiRequest->getResponseObjectByStatusCode(200).

If the API returns a non-2XX status, an exception is thrown of the type Payvision\SDK\Exception\Api\ErrorResponse. This exception has the error object with more information about what went wrong:

try {
    $apiResponse = $apiConnection->execute($apiRequest);
} catch (ErrorResponse $errorResponseException) {
    /** \Payvision\SDK\Domain\Payments\ValueObject\Response\Error $apiResponse */
    $errorResponse = $errorResponseException->getErrorResponse();


Webhooks can also be handled by the SDK. In order to do so you need the following input data:

  • The Event Signature (also known as a Json Web Token (JWT). This is sent in the header)
  • The secret that is used to sign the JWT
  • The body of the webhook (as string).

You can pass this data to the EventBuilder service of the webhook:

use Payvision\SDK\Application\Reflection\JsonToObject;
use Payvision\SDK\Application\Webhook\Service\EventBuilder;
use Payvision\SDK\Domain\Webhook\Service\Validator;

$eventBuilderService = new EventBuilder(
    new Validator(),
    new JsonToObject()

$event = $eventBuilderService->generateEvent(
    'event signature',
    'json body'

Since the payload of the webhook event can be a variety of objects, the Event::getPayload() cannot be type-hinted. So you might want to do some extra checks on this:

$payload = $event->getPayload();
if ($payload instanceof \Payvision\SDK\Domain\Payments\ValueObject\Response\Request) {

If you don't want this (because it might miss auto-completion in your IDE because of this), you can also use EventBuilder::generateDecoratedEvent() to get a EventDecorator that provides extra functionality so you don't have to guess what the payload is:

$decoratedEvent = $eventBuilderService->generateDecoratedEvent(
    'event signature',
    'json body'

if ($decoratedEvent->getPayloadType() === \Payvision\SDK\Domain\Webhook\Service\EventDecorator::TYPE_REQUEST) {
    $payload = $decoratedEvent->getRequestResponse();

The decorator also has some additional checks to make sure that the payload is known.

Developer information

If you want to analyze or improve this SDK, it's good to read the following information, targeted at developers:


The SDK is setup in a Domain Driven way. At the core are Value Objects, which are the stateless building blocks that are used in the API. Above that there are the aggregates, these combine the various Value Objects into implementations.

Aggregates are then converted to request objects, which are send to the API, which in turn returns a response object. Logic goes from bottom to top, dependencies go from top to bottom:

|   Value Object    |           Example: Transaction, Bank, Card, etc.
|                   |           These can be built manually, or by using the (composite) builders
   Request Builder              Builds request out of aggregate using reflection.
|      Request      |
      API Client                Does the request to the external API
   Response Builder             Generates a response object out of the API response data using reflection.
|      Response     |           Example: PaymentResponse
