Answer 1

You might want to look at this question too (link) which indicates you will have your application rejected by Apple. You need to look at the In App Purchase mechanisms to collect payments in an iPhone App

Answer 2

You appear to be mixing up two different ways of calling the PayPal API. You have a SOAP XML string, which you don't actually use and also then call the NVP (name value pair) API.

You need to decide which you are actually going to use.

The URLs you need to use for the NVP API are:

API Servers for API Signature Security

If you use an API signature, post the request to one ofthese servers:

Sandbox: https://api-3t.sandbox.paypal.com/nvp

Live: https://api-3t.paypal.com/nvp API Servers for API Certificate Security

If you use an API certificate, post the request to oneof these servers:

Sandbox: https://api.sandbox.paypal.com/nvp

Live: https://api.paypal.com/nvp

Additionally, I think you should URL-encode the name and value parameters that you're passing in.
