Firehose is Everflow’s real-time event streaming service. Instead of polling the REST API for new data, Firehose pushes events to your infrastructure as they happen — with sub-second latency and no rate limiting.

​
Why use Firehose

REST APIFirehose
DeliveryYou poll for dataEvents pushed to you
LatencyDepends on polling frequencySub-second
Rate limits20 requests/secondNone
Best forOn-demand queries, management operationsReal-time pipelines, data warehousing, live dashboards
Firehose is ideal when you need:
  • Real-time data ingestion into your data warehouse or BI tools
  • Live dashboards that update as events occur
  • Event-driven automation pipelines
  • Complete data replication without polling overhead

​
Supported event types

Firehose can stream any combination of these event types:
Event typeDescription
ClicksFired when a user clicks a tracking link. Includes device info, geolocation, query parameters, and attribution data.
ImpressionsFired when an impression pixel loads. Includes device and geolocation data. Requires the impression tracking package.
ConversionsFired when a conversion event is recorded. Includes conversion details, payout/revenue, event names, and custom parameters.
Conversion updatesFired when a conversion status changes (e.g., approved, rejected) or when payout/revenue values are modified.

​
Supported delivery platforms

Firehose supports the following delivery methods:

​
Amazon SQS

Events are delivered to an Amazon Simple Queue Service (SQS) queue. Supports both Standard and FIFO queue types.
  • Standard queues — Best-effort ordering, at-least-once delivery, maximum throughput
  • FIFO queues — Guaranteed ordering within message groups, exactly-once processing
You provide:
  • AWS Region
  • SQS Queue URL
  • IAM credentials or cross-account role ARN for Everflow to publish to your queue

​
Google Cloud Pub/Sub

Events are published to a Google Cloud Pub/Sub topic. Supports optional message attributes for custom routing. You provide:
  • Google Cloud Project ID
  • Pub/Sub Topic name
  • Service account credentials for Everflow to publish to your topic

​
HTTP/HTTPS POST

Events are delivered as JSON payloads via HTTP POST requests to your custom endpoint. You provide:
  • The URL to receive events
  • Any required authentication headers (e.g., API keys, bearer tokens)

​
Azure Event Hubs

Available on request. Contact Everflow Support to configure Azure Event Hubs delivery.

​
Event payloads

Each event is delivered as a JSON object. The payload structure is configurable — you can choose which fields to include and define custom field mappings.

​
Payload configuration

When setting up your Firehose, you can customize:
  • Field selection — Choose which fields to include in each event type
  • Field mapping — Rename fields to match your data schema (e.g., rename affiliate_id to partner_id)
  • Raw query parameters — Optionally include the full raw query string from the tracking URL
  • Event filtering — Stream only specific event types (e.g., conversions only)

​
Setup

Firehose is configured by the Everflow team. To get started:
  1. Choose your delivery platform — SQS, Pub/Sub, HTTP, or Azure
  2. Provision your infrastructure — Create the queue, topic, or endpoint on your side
  3. Contact Everflow Support — Provide your infrastructure details (queue URL, topic name, endpoint URL, and credentials)
  4. Configure your payload — Work with the Everflow team to define which fields and event types to include
  5. Start receiving events — Everflow enables the stream and events begin flowing in real time
