# AWS Resource Access Manager endpoints and quotas
<a name="ram"></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.

**Notes**  
The quota for **Number of pending invitations** applies to only *sending* accounts who share with accounts that are ***not*** part of sender's AWS Organization.
There is no quota for how many pending invitations a receiving account can have.
Invitations are not used when sharing between accounts that are part of the same AWS Organization and [resource sharing within that AWS Organization is turned on](https://docs.aws.amazon.com/ram/latest/userguide/getting-started-sharing.html#getting-started-sharing-orgs).
