s3/event

Amazon S3 sends event notifications to Lambda when objects are created, modified, or deleted in a bucket. S3 invokes your function asynchronously with an event that contains details about the object. You configure notifications on the S3 bucket to specify which events trigger the function.

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.

Browse every event-driven channel on the APIs.io network or compare with the broader Naftiko capability, Agent Skill, and MCP server surfaces of the same providers.
