Daily do i need to authorize DocuSign Connected System?

Daily i need to authorize to use the connected system.
Is it because I am using DocuSign Sandbox account?

I need to know is there any different plan which i need to purchase from docusign to use there service in appian for business(production).

Questions : 

1)Still do i need to daily authorize connected if i purchase subscription?

2)Is there any different plans of DocuSign  for Appian?
