Roboflow Vision Events¶

Class: RoboflowVisionEventsBlockV1

Source: inference.core.workflows.core_steps.sinks.roboflow.vision_events.v1.RoboflowVisionEventsBlockV1

Send images, model predictions, and event metadata to the Roboflow Vision Events API for monitoring, quality control, safety alerting, and custom event tracking.

How This Block Works¶

This block uploads workflow images and model predictions to the Roboflow Vision Events API, creating structured events that can be queried, filtered, and visualized in the Roboflow dashboard.

Optionally uploads an input image and/or output image (visualization) to the Vision Events image storage via the public API
Converts model predictions (object detection, classification, instance segmentation, or keypoint detection) into the Vision Events annotation format and attaches them to the input image
Creates a vision event with the specified event type, use case, event data, and custom metadata
Supports fire-and-forget mode for non-blocking execution

Event Types¶

quality_check: Manufacturing/inspection QA with pass/fail result and optional confidence
inventory_count: Inventory tracking with location, item count, and item type
safety_alert: Safety violations with alert type, severity (low/medium/high), and description
custom: User-defined events with a free-form value string
operator_feedback: Operator review/correction of previous events (correct/incorrect/inconclusive)

Requirements¶

API Key Required: This block requires a valid Roboflow API key with vision-events:write scope. The API key must be configured in your environment or workflow configuration.

Common Use Cases¶

Quality Control: Automatically log inspection results with images and detection overlays
Safety Monitoring: Send safety alerts when violations are detected in video streams
Production Analytics: Track inventory counts and production metrics with visual evidence
Active Monitoring: Fire-and-forget event logging from real-time video processing workflows

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/roboflow_vision_events@v1to add the block as as step in your workflow.

Properties¶

Name	Type	Description	Refs
`name`	`str`	Enter a unique identifier for this step..	❌
`event_type`	`str`	The type of vision event to create..	✅
`solution`	`str`	The use case to associate the event with. Events are namespaced by use case within a workspace..	✅
`external_id`	`str`	External identifier for correlation with other systems (max 1000 chars)..	✅
`qc_result`	`str`	Quality check result: pass or fail..	✅
`location`	`str`	Location identifier for inventory count..	✅
`item_count`	`int`	Number of items counted..	✅
`item_type`	`str`	Type of item being counted..	✅
`alert_type`	`str`	Alert type identifier (e.g. no_hardhat, spill_detected)..	✅
`severity`	`str`	Severity level for the safety alert..	✅
`alert_description`	`str`	Description of the safety alert..	✅
`custom_value`	`str`	Arbitrary value for custom events..	✅
`related_event_id`	`str`	The event ID of the event being reviewed..	✅
`feedback`	`str`	Operator feedback on the related event..	✅
`custom_metadata`	`Dict[str, Union[bool, float, int, str]]`	Flat key-value metadata to attach to the event. Keys must match pattern [a-zA-Z0-9_ -]+ (max 100 chars). String values max 1000 chars..	✅
`fire_and_forget`	`bool`	If True, the event is sent asynchronously and the workflow continues without waiting. If False, the block waits for the API response..	✅
`disable_sink`	`bool`	If True, the block is disabled and no events are sent..	✅

The Refs column marks possibility to parametrise the property with dynamic values available in workflow runtime. See Bindings for more info.
