Connections are sets of connection parameters to external providers. When a connection to an external provider is defined, you can use that connection in workflows anywhere on the SharePoint site.
You can limit connections to your user account if desired. Permissions checks for user-specific connections are performed during selection of connections in action configuration and during publishing of workflows.
External providers that use connections include DocuSign, Microsoft Dynamics CRM, and Salesforce. This list is not exhaustive; connection-specific providers are subject to change between releases of this product.
If a connection is deleted, then any currently running workflows that reference the connection are stopped and the workflows cannot be republished until a valid connection is selected for the affected actions.
