FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package pay

📦 PayKit Gateway SDK (Contracts + Payloads)

PHP Version

A business-agnostic, enterprise-grade Financial Infrastructure Protocol Engine that enables host PHP applications to integrate multiple payment and banking providers (Stripe, Adyen, Paystack, Flutterwave, Airwallex, Marqeta) through strict contracts and strongly-typed payloads.

🎯 What We Ship

❌ What We Do NOT Ship

Source of Truth: Only src/ is the SDK public API surface.

0) Installation & Requirements

PHP Version

Requires PHP 8.2+ with ext-json and ext-mbstring.

Composer

Namespace / Autoloading

This SDK is PSR-4 autoloaded under the Elqora\Pay\ namespace:

0.1) Laravel Integration (Service Provider Binding)

PayKit is framework-agnostic. In Laravel host applications, bind GatewayManager as a singleton in your AppServiceProvider:

1) Core Architectural Principles

1. Model-First (Host DB is Source of Truth)

Drivers discover support matrices (currencies, countries, capability flags) only during manifest synchronization, never at checkout runtime. Checkout filtering occurs in local database space without triggering high-latency third-party HTTP calls.

2. Host-Controlled Business Logic

Drivers communicate with payment vendors and report canonical statuses. The host application decides what "succeeded" means (e.g., crediting a user wallet, fulfilling an order, or releasing a digital asset).

3. Capability-by-Contract

New capabilities are introduced as discrete, isolated PHP interfaces in src/Contracts/. Feature support is verified via standard PHP runtime introspection ($driver instanceof PaymentGatewayBulkPayoutsContract).

4. Strict Typed Payloads & Idempotency

Core domain methods accept strongly-typed DTOs with explicit IdempotencyKey value objects and GatewayFailure error payloads.

2) Code Examples by Financial Domain

2.1 Core Payments & Elqora Interactions

Initiate a payment and receive a canonical status along with an Elqora Interaction (Redirect, Instructions, QrCode, Component, Mount, Script):

2.2 Outward Payouts, Sources & Typed Destinations

Route single payouts to bank accounts, mobile money wallets, cards, crypto addresses, or beneficiaries:

2.3 Bulk Payouts & Batch Transfers

Submit thousands of itemized payouts in a single batch with item-level status tracking:

2.4 Account Resolution & Destination Validation

Verify bank account numbers, IBANs, or mobile money names before payout execution:

2.5 Virtual Accounts & Compliance Identity (KYC / KYB)

Provision dedicated collection accounts or single-use payment vIBANs with structured compliance identifiers:

2.6 Balances, Double-Entry Ledgers & Internal Transfers

Inspect balance snapshots, query double-entry accounting transactions, or move funds internally:

2.7 Modular Virtual Cards & Spending Controls

Provision virtual cards, update velocity/MCC controls, process JIT webhook authorizations, or request PCI-isolated card reveal sessions:

2.8 Webhook Event Deduplication

Prevent duplicate business execution from third-party webhook retries using the framework-agnostic WebhookDeduplicator:

3) Canonical src/ Layout Sitemap

4) Driver Implementation Guide

To create a new PayKit driver (e.g. PayKitStripeDriver):

  1. Extend AbstractPaymentGatewayDriver (or implement PaymentGatewayDriverContract).

  2. Implement capability interfaces for features your provider supports:

  3. Register your driver with Pay:
