API token

There are two ways to use the token, our recomendation and good practice is to use the default environment variable PREXVIEW_TOKEN :

$ export PREXVIEW_TOKEN=<token>

In your application

# xml example
xml = "<xml>hello world</xml>"
code, response = PrexView.send_xml(xml, {type: 'xml', design: "design-xml"})
# json example
json = { "hello": "world" }
code, response = PrexView.send_json(json, {type: 'json', design: "design-json" })

The second way is to pass the token key as a parameter

# xml example
xml = "<xml>hello world</xml>"
PrexView.send_xml(xml, {type: 'xml', design: "design-xml", token: "<token>" })
# json example
json = { "hello": "world" }
code, response = PrexView.send_json(json, {type: 'json', design: "design-json", token: "<token>" })
