I want to know that can we make paypel related application in j2me and symbian OS?
Is it secure?
If we can make such application then can i get the api used for that.
Please help me for that.
If you are asking whether PayPal offers any SDK for using the service on said platform through library APIs, the answer is no. See https://www.x.com/community/ppx/sdks?bn_r=m
If you are asking whether you could implement the NVP/SOAP APIs on this platform is: you could and it could be secure. It all depends on you ;)
