I am developing an IOS app. I need to get Evernote note books using rest api. I don't want to use Evernote SDK. Is there any rest api available? I succeeded to get oAuth Access token without using SDK.
Evernote does not have a publicly available REST API. Evernote's iOS SDK has been rewritten recently, is very easy to use and is available here: https://github.com/evernote/evernote-sdk-ios
Evernote uses a binary protocol based on Apache Thrift to communicate with its clients including 3rd party clients such as your application, not HTTP. OAuth is a HTTP based protocol and is independent from Evernote's client-server binary protocol communication.
