PHP Framework
If your website or application is not built on one of the supported CMS or e-commerce platforms, you can integrate with Payneteasy directly from plain PHP using the official PHP client library. The library wraps the Payneteasy Merchant API (request signing, transport, response parsing and payment status handling) into a set of PHP classes, so you do not have to implement the API protocol yourself.
The library implements the following payment scenarios:
Account verification
Sale transactions
Preauth/Capture transactions
Transfer transactions
Return transactions
Recurrent transactions
Payment Form integration
Merchant callbacks
Buy Now Button, eCheck, Western Union, Bitcoin, Loan and Qiwi integrations are listed in the library’s own documentation as not yet implemented.
Source code
The library is published on GitHub: payneteasy/php-library-payneteasy-api. The repository README links to more detailed documentation pages (in English and Russian) describing the library’s internal structure and each payment scenario in more depth.
