Batch Create Vision Events

Record up to 100 Vision Events in a single request to ingest many observations at once.

About

This endpoint records multiple Vision Events in a single request, up to 100 at a time. Use it when a deployment needs to ingest many observations at once, which is more efficient than creating events individually. To record a single event, see Create a Vision Event.

HTTP API

Create up to 100 vision events in a single request. This is more efficient than creating events individually when you need to ingest multiple events at once.

To include images in your events, first upload each image using the Upload a Vision Event Image endpoint, then reference the returned sourceId in the image object. See Image Objects for details.

Python SDK

Create multiple vision events in a single request. The server allows up to 100 events per batch.

import roboflow

roboflow.login()

rf = roboflow.Roboflow()
ws = rf.workspace()

result = ws.write_vision_events_batch([

        "customMetadata": {"line": "A1"},
    },
])

print(result["created"])    # Number of events created
print(result["eventIds"])   # List of created event IDs

Each event in the list follows the same schema as a single event. For full details on event schemas and validation behavior, see the REST API reference.
