FAQ
Example:
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 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.

CMPayments Payment SDK for PHP
Integrating the CMPayments solutions for online payments with your application is easy using the Payment SDK for PHP.
Installation
To install the SDK, simply use Composer:
Requirements
- PHP 5.5+
- PHP cURL extension
- Up to date SSL, capable of TLS 1.0 or higher
Dependencies
- MoneyPHP is used to encapsulate sums of money and their currency
- Guzzle is used to make HTTP requests
These are automatically installed by composer.
Bootstrapping
To do anything with the SDK, the first step is to create an instance of the payment Gateway:
List iDEAL issuers
To get a list of iDEAL issuers, simply tell the Gateway to execute the IdealIssuerListRequest:
Start a payment
The CMPayments API supports the concept of a Charge that contains 0..n Payment items underneath it. To start a payment, both a Charge and a Payment must be created.
This can be done in one request:
Note: Each payment method has its own {METHOD}Payment class.
Each of these classes enforces all required properties trough their constructors.
For instance, to create a new CreditCard payment, replace the new IdealPayment(...) line with new CreditCardPayment(Money::EUR(500), ['VISA', 'MasterCard'], 'your-purchase-id', new \DateTime('+1 day'));.
Retreive charge or a payment
Simple tell the Gateway to execute a ViewChargeRequest of ViewPaymentRequest with the correct id, and the details will be retrieved.
Handling errors
Internally, Guzzle is used to make HTTP requests. When the API responds with a 4xx or 5xx HTTP status, either a ClientException or a ServerException is thrown.
In case of a ServerException, the CMPayments platform is having issues. Try the request again later.
For a ClientException, check $exception->getResponse()->getBody()->getContents() to see what is wrong.
Working with Money
The Money library in use requires that any amount is represented in the smallest unig (eg. cents),
so EUR 5,- is written as new Money(500, new Currency('EUR')) or shorter as Money::EUR(500).
Because this can be a bit of a hassle, the MoneyConverter class is provided. It can convert a float + currency into a Money object and back.
