# Event source mapping parameters
<a name="services-mq-params"></a>

All Lambda event source types 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 Amazon MQ and RabbitMQ.
