Manually Setting Up Composer Link Service for Existing Solutions
Use Conga Link Service in existing Composer solutions. You must enable Composer Link Service and the Conga File Repository to setup and use Composer Link Service. Additionally, you must enable Notification Emails in Conga Composer Setup to send Notification Emails.
The solution must have a Conga Email Template (CongaEmailTemplateID parameter) to send a document with Composer Link Service in an email.
Modify an existing Composer solution in Salesforce Setup to leverage Composer Link Service.
