I need a fulfillment company's web services integrated with the WorldPay Junior payment services.
Shipping information (state, country) will be gathered from the user, the system will query the fulfillment company's web service for available shipping options and prices. The user will then need to select their shipping method, the
total is calculated and forwarded onto WorldPay where the user will finish the transaction. Via a WorldPay callback the purchase will need to be validated and then the order sent on to the fulfillment company's via a web service that they provide.
Reading from a configuration file will be needed.
There will only ever be 1 item ordered at a time, so no shopping cart is needed, but there may be more than one script or checkout process on a site(because there are multiple products on offer).
The scripts must be able to handle multiple currencies.
Each script except the callback should be able to be inserted into any html page so that the sites look & feel can be maintained. Though entire pages should be included for a default installation.
The process must be spoof proof and bug free.
Detailed Installation Instructions will need to be provided so that a non-technical person may install it.
If the solution requires a database setup, then scripts for MySql setup will need to be provided. A solution
using a database is strongly discouraged and not thought to be needed.
More details are attached.
