Digest Step

Digest step to batch multiple notifications. Place BEFORE channel steps.

​

Digest Types

• regular (default):
  • With a look-back window — digest only if a recent message was sent.
  • Without a look-back window — groups all events that arrive within the time window.
• timed — with a cron expression, collects events until the scheduled time (UTC).

​

Common Patterns

• Pass the first event immediately, digest the rest.
• Batch activity updates hourly.
• Group by key (e.g. payload.projectId) for per-project digests.

​

Accessing Digested Events Downstream

Steps after a digest step can reference:

• steps.<digest-step-id>.events — the array of digested events (use with a repeat node in Block Editor or a {% for %} loop in HTML).
• steps.<digest-step-id>.eventCount — the number of digested events.

See email-step.md for the Block Editor repeat + current.payload.* pattern.
