Lambda function target
To deliver to a Lambda function, set TargetArn to the function ARN, optionally with an alias
or version, and add LambdaParameters. The function receives a JSON array holding the events in
the batch, one element per event, even when the batch holds one event.
Parameters
| Parameter | What it sets |
|---|---|
InvocationType | EVENT invokes asynchronously and treats a successful Invoke as delivered. REQUEST_RESPONSE waits for the function to return and treats a function error as a failed delivery |
Qualifier | A function version or alias, if not part of the ARN |
DurableExecutionName | The name of a durable execution, for functions that use durable execution |
TenantId | The tenant identifier passed to a multi-tenant function |
InvocationTimeoutSeconds | How long EventBridge waits for the call, 1 to 30 seconds, default 30 |
Delivery role
The role needs lambda:InvokeFunction on the function, including its alias or version if
you name one.
Batching and payload
One Invoke carries the whole batch as a JSON array. Set
BatchConfiguration.MaxBatchSize to 1 if the function expects one event per invocation. See
Batching deliveries to a target.
