# Lambda parameters for Amazon Kinesis Data Streams event source mappings
<a name="services-kinesis-parameters"></a>

All Lambda event source mappings share the same [CreateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_CreateEventSourceMapping.html) and [UpdateEventSourceMapping](https://docs.aws.amazon.com/lambda/latest/api/API_UpdateEventSourceMapping.html) API operations. However, only some of the parameters apply to Kinesis.


| Parameter | Required | Default | Notes |
