Paypal, Netteller PaymenGateways Connectors
It should be a great demand for Connectors for various Payment solutions
Any progress with this , it seems like you have started to plan it:
Searching the web I found and tested this Paypal- Sql Server integration from Zapier.com a very simple connector see https://zapier.com/zapbook/paypal/sql-server/ ...
With this Zap connection there is no need for any code to integrate paypal with sql server... if you reuse the sqlserver sample and provide a similar solution to integrate paypal with AzureSql bypassing (azure table http requests and any need for any code to implement it) than even less experienced developers will be able to set up a payment solution in minutes independent of development language used : )
