AWS Lambda

Invokes an AWS Lambda function for each event, sending the json-encoded payload through the AWS API. Use it to trigger custom serverless logic — alerts, enrichment, downstream writes — whenever a matching event appears on chain.

The sink processes events in sequence: it invokes the function, waits for the response, then moves on to the next event.

Authentication uses the standard AWS provider chain — no credentials go in the config. See AWS credentials for the supported options.

Configuration

daemon.toml
[sink]
type = "AwsLambda"
region = "us-east-1"
function_name = "my-lambda"
  • type (required): the literal value AwsLambda.
  • region (required): the AWS region where the function lives.
  • function_name (required): the ARN of the function to invoke.

Retries cover dispatch, not execution

Oura retries failures to dispatch the call, but not failures inside the function. Whether the function succeeds or not, the sink advances to the next event — so the function itself must handle its own errors and idempotency.
