# PUT /2019-09-25/functions/{FunctionName}/event-invoke-config

`PUT /2019-09-25/functions/{FunctionName}/event-invoke-config`

Configures options for [asynchronous invocation](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html) on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

To send an invocation record to a queue, topic, function, or event bus, specify a [destination](https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#invocation-async-destinations). You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.
