I’ll introduce how to obtain an API Key to use the Evernote API.
The Evernote Japanese official help had links about the API (some dead links).
First, click the [GET AN API KEY] button on the Evernote developer page.
A form called Request an Evernote API Key. will be displayed, so fill in the required fields.
Immediately, a page titled Your Evernote API Key is Ready will display the Consumer Key and Consumer Secret, so use these to proceed with development.
By the way, immediately after obtaining the Evernote API Key, it can only be used at https://sandbox.evernote.com/.
After testing your app in the sandbox environment, apply for activation by clicking the [Activate an API Key] button from the Support - Evernote Developers page.
The next step would be to proceed with developing your app using the Evernote API.
The Evernote API documentation can be referenced at http://dev.evernote.com/doc/, so read only the necessary parts and proceed with app development.
That’s all from the Gemba, where we want to use the Evernote API.
