Compute how a single channel acquired people across each event it appeared on. The response carries the channel’s membership context plus a per-event breakdown of who joined the channel because of that event and who was already on it. The dashboard Channel attribution card uses the same query.

​
Synopsis

​
Arguments

ArgumentTypeDescription
<channelId>integerChannel ID. Use channel list to find one.

​
Options

​
Examples

​
1. Attribution for a single event

talkvalue path analysis channel attribution 7 --event-id 18 --json
Returns the channel’s headline metrics plus a one-element events array containing the breakdown for event 18.

​
2. Roll up every event on a channel

talkvalue path analysis channel attribution 7 --json \
  | jq '{
      channel: .data.channel.name,
      eventParticipationRate: .data.metrics.eventParticipationRate,
      events: (.data.events | map({name, total, joinedSinceLastEvent, acquisitionRate}))
    }'
Projects each event down to the four fields you typically chart, leaving the channel headline metrics on top.

​
3. Tag-scoped attribution report

talkvalue path analysis channel attribution 7 --tag-id 4 --json \
  > "reports/channel-7-attribution-$(date +%Y-%m-%d).json"
Captures the attribution snapshot for tagged events (for example, every webinar). Drop into a cron job to keep a daily archive.
