Can I use Packlink with a basic fare on Shopify's trial period?

Hi,

I am testing Shopify’s trial period and I need to know if is posible to use Packlink with the Shopify’s basic fare.

At this moment, I cannot set up my account of Packlink (adding shipment services) , I gues for the trial period .. but I don’t if I will add services with the basic fare.

Thank you!
