Below are a few things needed before getting started with the Locale API.
A Locale account
An API project
An API key
An account can easily be created here or by going to https://app.locale.to .
Once signed up, add an API project to your workspace, and from the project settings you can find your API key.
In the settings you can also change other settings, like your source language (eg. English) and the callback URL.
While in the project, add as many languages as necessary for the intended project.
