# AWS AppSync endpoints and quotas
<a name="appsync"></a>

To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).

Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).

The following are the service endpoints and service quotas for this service.

**Rate of request tokens** is the maximum number of request tokens per second in this account in the current Region. AWS AppSync allocates tokens to mutation and query requests based on the amount of resources (processing time and memory) that they consume. For more details on tokens, see [Using token counts to optimize your requests](https://docs.aws.amazon.com/appsync/latest/devguide/monitoring.html#aws-appsync-using-token-counts-to-optimize-requests) in the *AWS AppSync developer guide*.
