The three elements you will now need to make a request in API Version 3 are: Company API Key, Rightsline Access Key, and Rightsline Secret Access Key. The Company API Key is shared among your organization and is unique per environment (Staging, Integration, Prod Mirror, and Production). Your Access Key and Secret Access Key is unique for your API User account. It will inherit the security policy that is attached to your account.
Contact your Rightsline representative to receive your Company API Key.
Login to your user account from https://admin.rightsline.com.
Open your Profile from the drop-down menu, and in the API Access module, click Generate Access Keys.
Once you have your Company API Key, and your User Account's Access and Secret Key, you are ready to make your first API request.
