# Quotas in Amazon MQ
Quotas

This topic lists limits within Amazon MQ. Many of the following limits can be changed for specific AWS accounts. To request an increase for a limit, see [AWS Service Quotas](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html) in the *Amazon Web Services General Reference*. Updated limits will not be visible even after the limit increase has been applied. For more information on viewing current connection limits in Amazon CloudWatch, see [ Monitoring Amazon MQ brokers using Amazon CloudWatch](https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/security-logging-monitoring-cloudwatch.html).

## API Throttling


The following throttling quotas are aggregated per AWS account, *across all Amazon MQ APIs* to maintain service bandwidth. For more information about Amazon MQ APIs, see the *[Amazon MQ REST API Reference](https://docs.aws.amazon.com/amazon-mq/latest/api-reference/)*.

**Important**  
These quotas don't apply to Amazon MQ for ActiveMQ or Amazon MQ for RabbitMQ broker messaging APIs. For example, Amazon MQ doesn't throttle the sending or receiving of messages.
