MyBring Api

Hi,

I am trying to get this APIs on my WooCommerce site: Booking API: http://developer.bring.com/api/booking/

Tracking API: http://developer.bring.com/api/tracking/

and Purchase order API http://developer.bring.com/api/purchase-order/

I have activated the API key. But I have no idea what to do next? Where should I put the codes? I am sorry, this is my first time developing a website/webshop and using shortcodes. I hope you can help!

Kind regards,
Kjersti
