As it may be useful to others, we received this feedback from ShipWorks for adding their extension to Magento2:
Here is the brief rundown: In ShipWorks, add store > Select Magento 2 and enter the Token and Module URL so that ShipWorks can communicate with your Magento 2 store: o Token (obtained by following the steps provided by Magento) o Module URL (something like http://yourstorename/rest/v1/shipworks) o Store code (optional, if entering more than one Magento store)
Here are more detailed instructions: After installing the extension from Magento Marketplace... Return to the admin dashboard. System > Integration > Add New Integration > Create a Name (name it whatever you would like to name it) > Enter the admin password > Save. Locate the name you just created > Edit > API > Check the box next to sales to select all roles associated with Sales. > Integration info> Enter admin password > Save. Activate > Verify that that Sales roles are selected > Allow Copy the “Access Token”. The Access Token will be entered in the “Token” field in the ShipWorks application.
