Integration into PayU's Enterprise API is accomplished server side SOAP API calls as this provides an extra layer of security.
In order to complete a successful integration, it is recommended to first do a test integration against the PayU staging environment with details given in the test overview section, before moving to the production environment. Once the test integration process is complete, the staging details will need to be substituted with the production detail. This detail will be provided by PayU once confirmation of a successful test integration has been received.
Example customer payment sequence
It should be noted that the sequence set out above, is only for a golden path integration and more test cases as well as recommendations are given in test overview section. The summarised payment sequence can change and is dependent on the transaction type used in the doTransaction call.
