# Getting Started

Express Checkout APIs are built around basic HTTP communication and closely
follows the standards of REST. While the URL themselves are not specific to
resources, the URL path is intuitive to reflect the action performed by the API.

        def deps do
          [{:juspay_expresscheckout, "~>0.1.0"}]
        end


  2. Update mix dependencies (mix deps.get)  & Ensure `juspay_expresscheckout` is started before your  application:


        def application do
          [applications: [:juspay_expresscheckout]]
        end
