# Real-Time Event Streams Overview

> Stream Mixpanel events to a custom webhook within seconds of ingestion to power activation, personalization, and downstream data workflows.

> [!NOTE]
>
> **Beta.** Real-Time Event Streams are currently available to a limited set of customers during Beta. If you'd like to participate, reach out to your Mixpanel account team.

Real-Time Event Streams deliver Mixpanel events to your infrastructure within seconds of ingestion, so you can react to user behavior without waiting for a batch export.

## What you get in the beta

> **Low-latency delivery**
>
> p95 delivery within 120 seconds of event ingestion.

> **Custom webhook destination**
>
> Send events to any HTTPS endpoint you control, with your own auth and payload shape.

> **Event and property filters**
>
> Stream only the event types and property values that matter to your use case.

> **Liquid-templated payloads**
>
> Fully control the outbound request body, including field names and identity.

## When to use streams

Use Real-Time Event Streams when latency matters and your workflow needs individual events as they happen:

* **Live activation** — trigger emails, pushes, or in-app messages seconds after a qualifying event.
* **Operational alerting** — feed on-call systems when key events are triggered.
* **Personalization** — update recommendations and experiences based on the user's current behavior.
* **Downstream pipelines** — fan events into your own queues or services for custom processing.

## How Real Time Streams compare to Data Pipelines

[Data Pipelines](https://docs.mixpanel.com/docs/data-pipelines) deliver batches of events to warehouses and object stores on a schedule. Real-Time Event Streams deliver individual events with low latency to an HTTP endpoint you control. Use pipelines for analytics and reporting workloads; use streams when you need to act on events within seconds.

## Key Concepts

* **Destination** — the webhook endpoint and its authentication configuration.
* **Stream** — a rule that binds a set of filtered events and a Liquid payload template to a Destination.

## Delivery guarantees at a glance

* **At-least-once delivery.** You can include the Mixpanel Insert ID property in the payload so you can deduplicate on your side.
* **Automatic retries.** Transient failures (5xx, timeouts, network errors) are retried up to 4 times with exponential backoff. Permanent failures (4xx) are surfaced as configuration errors.
* **Latency.** p95 ≤ 120 seconds from ingestion to a confirmed 2xx response at your endpoint under normal load, often times even faster.

See [Delivery and reliability](https://docs.mixpanel.com/docs/real-time-event-streams/delivery-and-reliability.md) for the full behavior.
