The short answer
What is the dpay SDK for PHP?
A dpay SDK is an official library that simplifies online payment integration with the dpay API. It reduces custom code for checksums, API calls, IPN verification and error handling.
Backend ecosystem
PHP payments in popular frameworks and custom architectures.
The SDK is a backend library. Keep the dpay client in your service layer and load Payment Point credentials from secure server configuration.
Symfony
In a Symfony application, keep the PHP SDK client in the service layer shared by checkout and IPN handling.
Własny backend PHP
In a Własny backend PHP application, keep the PHP SDK client in the service layer shared by checkout and IPN handling.
Integration layer
Payment plumbing you do not need to build from scratch.
The PHP library wraps recurring payment lifecycle tasks in methods and types that fit the language ecosystem.
Checksums without manual assembly
The library calculates the checksum required for each request.
Request integrity
Payment lifecycle
Ready methods simplify payment registration and transaction handling.
Less HTTP code
Verified IPN
The SDK helps validate a notification before the order status changes.
Secure webhooks
Controlled errors
Exceptions and error codes make logging, retries and diagnosis clearer.
Predictable handling
Starter code
Create a dpay client in PHP.
Get service credentials from the Payment Point settings. Store the Secret Hash in environment configuration or a secrets manager, never in the repository or frontend code.
Secret Hash → server only
use DPay\DPayClient;
$dpay = new DPayClient([
'service' => 'service_name',
'secret_hash' => 'secret_hash',
]);Implementation flow
From a Payment Point to a confirmed order.
The secure implementation flow stays the same across technologies.
- 01
Install the library
Add the official package to your backend and pin the version according to your project rules.
- 02
Configure the client
Pass the service name and Secret Hash from secure server configuration only.
- 03
Register the payment
Send the amount plus success, failure and IPN URLs, then redirect the customer to the returned payment URL.
- 04
Verify IPN
After successful notification verification, update the order status in your database.
Other technologies
The same API in your team's backend.
Compare the available libraries and choose the language that best fits your product architecture.
Integrator FAQ
Before the first line of code.
How do I add online payments in PHP?
Install the package with “composer require dpayglobal/dpay-php-sdk”, create a client with the service name and Secret Hash, then call the payment registration method described in the PHP SDK documentation.
Does the SDK generate checksums?
Yes. Published dpay SDKs calculate checksums according to the API specification. The Secret Hash must still remain secure on the server.
How does the SDK handle IPN?
The library helps verify the IPN signature and parse the notification. Change order state only after successful verification.
Which dashboard credentials do I need?
You need Payment Point credentials, primarily the service name and Secret Hash. See the library documentation for its complete requirements.
