# Digest and Batched Notifications

> Batch and summarize notifications with Novu digest steps. Send digests like "10 new comments" instead of individual alerts.

Batch related notifications into a single digest message using Novu's digest step. Instead of sending one notification per event, Novu collects events over a time window and delivers a summarized message such as "10 people liked your post."

## How does digest work in Novu?

Add a [digest step](/platform/workflow/add-and-configure-steps/configure-action-steps/digest) to your workflow before the channel step. Novu collects events that match the digest key within the configured window, then renders a single notification with aggregated content.

Typical digest settings:

* **Window:** 5 minutes, 1 hour, or 24 hours depending on urgency
* **Digest key:** A field such as `payload.postId` to group events
* **Template:** Use digest variables to list aggregated items

## When should I use digest notifications?

| Scenario        | Digest window | Example message                |
| --------------- | ------------- | ------------------------------ |
| Social activity | 1–24 hours    | "10 people liked your post"    |
| Weekly summary  | 7 days        | "Your weekly activity report"  |
| Comment threads | 15–60 minutes | "5 new replies on your thread" |

## How do I trigger events for digest workflows?

Trigger the same workflow for each individual event. Novu handles batching automatically based on the digest step configuration and digest key.

```bash theme={null}
curl -X POST https://api.novu.co/v1/events/trigger \
  -H "Authorization: ApiKey <NOVU_SECRET_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "post-liked",
    "to": { "subscriberId": "user_123" },
    "payload": { "postId": "post_456", "likerName": "Alex" }
  }'
```

## Frequently asked questions

<AccordionGroup>
  <Accordion title="What is the difference between digest and throttle?">
    Digest batches multiple events into one summarized notification. Throttle limits how often a subscriber receives notifications for the same workflow within a time window.
  </Accordion>

  <Accordion title="Can I send digests across multiple channels?">
    Yes. Place digest before multiple channel steps (for example, in-app and email) so all channels receive the batched summary.
