I am trying to use PayPalMPL 2.1.7 for iOS to accept third party payments in my app. When I use this code to initialize the environment:
[PayPal initializeWithAppID:@"APP-80W284485P519543T" forEnvironment:ENV_SANDBOX];
I get this error in the log: Checking Error******************** Posting Error: -1
and this error as an alert in the app: Error internal server error
I would love to upgrade to the new PayPal iOS SDK, but it doesn't offer third party payments yet. Any idea what will fix these errors? Thanks!
