This API links an external account to a client organization. This account can be used by the client organization as a source account to transfer funds into an FBO Contribution account. When the name of the child client organization is passed, the external account will be linked to the child client organization. If the name of the child client organization is not passed, the external account will be linked to the client organization. In its response, this API returns a UUID that uniquely identifies the linked account object.
