 * Create one or more environment variables

 * Create one or more environment variables for a project by passing its `key`, `value`, `type` and `target` and by specifying the project by either passing the project `id` or `name` in the URL. If you include `upsert=true` as a query parameter, a new environment variable will not be created if it already exists but, the existing variable's value will be updated.
