AWS CloudTrail endpoints and quotas
The following are the service endpoints and service quotas for this service. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more information, see AWS service endpoints. 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.

Service quotas
| Name | Default | Adjustable | Description |
|---|---|---|---|
| Conditions across all advanced event selectors | Each supported Region: 500 | No | If a trail uses advanced event selectors, a maximum of 500 total values for all conditions in all advanced event selectors is allowed. Unless a trail logs data events on all resources, such as all S3 buckets, a trail is limited to 250 data resources. Data resources can be distributed across event selectors, but the total cannot exceed 250. |
| Data resources across all event selectors in a trail | Each supported Region: 250 | No | If you choose to limit data events by using event selectors or advanced event selectors, the total number of data resources cannot exceed 250 across all event selectors in a trail. |
| Event data stores per region | Each supported Region: 10 | No | The maximum number of event data stores per region. |
| Event selectors | Each supported Region: 5 | No | The maximum number of event selectors per trail. |
| Event size | Each supported Region: 256 Kilobytes | No | The maximum event size (in KB). All event versions: events over 256 KB cannot be sent to CloudWatch Logs. Event version 1.05 and newer: maximum event size of 256 KB. |
| Trails per region | Each supported Region: 5 | No | The maximum number of trails per region. |
| Transactions per second (TPS) for all other APIs | Each supported Region: 1 | No | The maximum number of operation requests you can make per second without being throttled. |
| Transactions per second (TPS) for the LookupEvents API | Each supported Region: 2 | No | The maximum number of operation requests you can make per second without being throttled. |
| Transactions per second (TPS) for the get, describe, and list APIs | Each supported Region: 10 | No | The maximum number of operation requests you can make per second without being throttled. The LookupEvents API is not included in this category. |
