 The ConnectWise ClientID is a required header that must be included with all API Requests.  The header is used to track API performance, usage statistics and is designed to ensure integrations don't fall into endless loops.  When creating a new API you can request either a Private or Public key.  The private key should only be used for internal integrations, whereas the public key is for a one to many and our Marketplace Vendors.

ClientID's are unique GUIDs that are designed to be per integration.  If you have multiple Integrations, please create multiple GUIDs.
