API Services


Playtia provides REST API services, allowing our customers and system integrators to programatically control the Paytia transaction processing service from their own web/database applications.

Paytia have three versions of API services

1. The main Paytia API service is called the 'PAYMENT SERVICE API'. It allows our customers to use multiple Paytia services from one central API integration and post to request an iframe service form.
2. For applications that cannot work with popup HTML windows or iframe services, Paytia has an 'URL POST' API. This API accepts data inside an encoded POST URL and extracts the data values to pre-populate the Paytia Agent Capture Assist User Interface form which is automatically generated and shows as a redirect.
3. Bespoke - Paytia creates bespoke API services for custom applications or workflow/transaction processing journeys.
