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 canvas-payments-adyen

Adyen Payment Provider

An Adyen payment provider for the Canvas framework. Part of the Canvas payments ecosystem.

Installation

Architecture

This package sits between the Adyen API and your application. Your application only ever touches the contracts layer — it never depends on this package directly. PaymentRouter (from quellabs/canvas-payments) discovers this package automatically via composer metadata and routes payment calls to it.

Notification processing is decoupled from your application via signals. When Adyen sends a notification, the package emits a payment_exchange signal carrying a PaymentState. Your application listens for that signal and handles it.

Configuration

Create config/adyen.php in your Canvas application:

Key Required Description
test_mode No Enable Adyen test environment. Defaults to false
api_key Yes Your Adyen API key. Found in Customer Area under Developers → API credentials. Use a test credential when test_mode is true
merchant_account Yes The Adyen merchant account name (not the company account). Found next to the account switcher in Customer Area
hmac_key Yes HMAC key for verifying incoming webhook signatures. Generated per webhook under Developers → Webhooks → Edit webhook
live_endpoint_prefix No Required when test_mode is false. Found in Customer Area under Developers → API URLs. Format: <random>-<merchantAccount>
return_url Yes URL the customer is redirected to after the package handles the return
cancel_return_url Yes URL the customer is redirected to after the package handles the cancel
webhook_url Yes Full URL Adyen POSTs webhook notifications to. Must be publicly reachable. Configure under Developers → Webhooks
default_country No ISO 3166-1 alpha-2 country code used when calling getPaymentOptions() without a transaction context (e.g. 'NL')
default_currency No ISO 4217 currency code used when calling getPaymentOptions() without a transaction context (e.g. 'EUR')

Usage

Initiating a payment

Inject PaymentInterface via Canvas DI and call initiate():

Handling refunds

Adyen refunds reference the pspReference from the original payment, which is exposed as transactionId on PaymentState. No additional metadata needs to be persisted — the transactionId from your payment_exchange listener is sufficient.

Note: Adyen processes refunds asynchronously. The refundId in the result is a pspReference for the refund request itself. The final REFUND notification arrives separately and triggers a payment_exchange signal with PaymentStatus::Refunded.

Listening for payment state changes
