I want to enable customers to purchase credit for use on my website by SMS.
Currently they purchase credit for using on my website through Paypal.
Paypal IPN means that once payment is made, the database is automatically updated to add the credit to that user's account. The same must happen when people pay by SMS, and their account must be immediately updated.
I have an account sent up with [url removed, login to view] so ideally I'd like to use them, however another system that will function in the UK is fine, as long as their rates aren't too high.
The user information is stored in a MS Access database.
The integration docs for mobillcash can be found here:
[url removed, login to view][^%3E]*%3E6\s%2B-\s%2BBilling\s%2BStatus\s%2BNotification&hilite0_colour=20FF20&hilite0_regex=6\s%2B-\s%2BBilling\s%2BStatus\s%2BNotification&tf=0#hlanchor
People will only have the option of purchasing 5 credits, or 10 credits for use on my site, so there is no need to code for any more payment variables than just the two.
The systems should interact using HTTP Post.
