Flow Message IDs, Names via API

Is there a way to access a list of flow message IDs and flow message names via API? I’ve tried numerous calls for flows, lists, and campaigns but none appear to include any flow message name or ID. 

Ideally, accessing flow message names and IDs would be useful to then loop through calls such as 

curl https://a.klaviyo.com/api/v1/metric/RECEIVED_EMAIL_METRIC_ID/export -G \
    -d api_key=API_KEY \
    -d unit='week' \
    -d measurement='count' \
    -d where='[["$message","=",'MESSAGE_ID']]'

and use the relevant message ID for a specific flow.
