Limits

Lists information about limits in your org. For each limit, this resource returns the maximum allocation and the remaining allocation based on usage. This resource is available in REST API version 29.0 and later for API users with the View Setup and Configuration permission. The resource returns these limits:

Limit Label	Description
Analytics
`ConcurrentAsyncGetReportInstances`	Concurrent REST API requests for results of asynchronous report runs
`ConcurrentSyncReportRuns`	Concurrent synchronous report runs via REST API
`HourlyAsyncReportRuns`	Hourly asynchronous report runs via REST API
`HourlySyncReportRuns`	Hourly synchronous report runs via REST API
`HourlyDashboardRefreshes`	Hourly dashboard refreshes via REST API
`HourlyDashboardResults`	Hourly REST API requests for dashboard results
`HourlyDashboardStatuses`	Hourly dashboard status requests via REST API
Email
`MassEmail`	Daily number of mass emails that are sent to external email addresses via Apex or APIs
`SingleEmail`	Daily number of single emails that are sent to external email addresses For orgs created before Spring ’19, the daily limit is enforced only for emails sent via Apex and Salesforce APIs except for the REST API. For orgs created in Spring ’19 and later, the daily limit is also enforced for email alerts, simple email actions, Send Email actions in flows, and REST API. If one of the newly counted emails can’t be sent because your org has reached the limit, we notify you by email and add an entry to the debug logs. Note
Lightning Platform REST and Bulk APIs
`DailyApiRequests`	Daily API calls
`DailyBulkApiBatches` (API version 49.0 and later) or `DailyBulkApiRequests` (API version 48.0 and earlier)	Daily Bulk API and Bulk API 2.0 batches. In Bulk API, batches are used by both ingest and query operations. In Bulk API 2.0, batches are used only by ingest operations.
`DailyBulkV2QueryFileStorageMB`	Daily storage for queries in Bulk API 2.0 (measured in MB). This limit is available in API version 47.0 and later.
`DailyBulkV2QueryJobs`	Daily number of query jobs in Bulk API 2.0. This limit is available in API version 47.0 and later.
Platform Events
The following values apply only to platform events. They don’t apply to Change Data Capture events.
`HourlyPublishedPlatformEvents`	High-volume platform event notifications published per hour
`HourlyPublishedStandardVolumePlatformEvents`	Standard-volume platform event notifications published per hour (You can no longer define standard-volume events. New platform events are high volume by default.)
`DailyStandardVolumePlatformEvents`	Daily standard-volume platform event notifications delivered to CometD clients (You can no longer define standard-volume events. New platform events are high volume by default.)
Platform Events and Change Data Capture
`MonthlyPlatformEventsUsageEntitlement` (API version 48.0 and later)	Org With Add-On License: Monthly Usage-Based Entitlement If your org has the high-volume platform event or Change Data Capture add-on, use `MonthlyPlatformEventsUsageEntitlement`. This value is the monthly entitlement and usage of event delivery to CometD clients and is incremented for each client. This value doesn’t apply to non-CometD subscribers, such as Apex triggers, flows, and processes. This value includes usage for both high-volume platform events and Change Data Capture events. Usage tracking frequency: `MonthlyPlatformEventsUsageEntitlement` is updated once a day. The entitlement is reset every month after your contract start date. Entitlement usage is computed only for production orgs. It is not available in sandbox or trial orgs. For more information, see Usage-based Entitlement Fields. With an add-on license, you can exceed the maximum entitlement by a certain amount. As a result, the remaining value returned can be negative if you exceeded the maximum value. Use `MonthlyPlatformEventsUsageEntitlement` with API version 48.0 or later to get an accurate event delivery usage based on the first day of your contract. In API version 47.0 and earlier, the `MonthlyPlatformEvents` value returns the usage based on the first of the month instead of the contract start date.
`MonthlyPlatformEvents` (API version 47.0 and earlier)	Org Without Add-On License: Daily Default Allocation If your org doesn’t have the high-volume platform event or Change Data Capture add-on, use `MonthlyPlatformEvents`. This value contains the default allocation and usage for event delivery to CometD clients and is incremented for each client. This value doesn’t apply to non-CometD subscribers, such as Apex triggers, flows, and processes. To get the limit that is enforced daily, divide the monthly value returned by 30. `MonthlyPlatformEvents` includes usage for both high-volume platform events and Change Data Capture events. Usage tracking frequency: `MonthlyPlatformEvents` is updated within a few minutes after event delivery.
Private Connect
`PrivateConnectOutboundCalloutHourlyLimitMB`	Maximum amount of data in bytes that can be transferred per hour via outbound private connections.
Salesforce Connect
`HourlyLongTermIdMapping`	Hourly new long-term external record ID mappings
`HourlyODataCallout`	Hourly OData callouts
`HourlyShortTermIdMapping`	Hourly new short-term external record ID mappings
Salesforce Developer Experience
`ActiveScratchOrgs`	Daily and active scratch org counts
Salesforce Functions
`DailyFunctionsApiCallLimit` (API version 53.0 and later)	Daily API calls in an org with Functions. Values are visible only if Salesforce Functions is enabled. For more information, see Functions Limits.
Storage
`DataStorageMB`	Data storage (MB) (The API user must have the Manage Users permission)
`FileStorageMB`	File storage (MB) (The API user must have the Manage Users permission)
Streaming API—Durable (API version 37.0 and later)
`DailyDurableGenericStreamingApiEvents`	Generic events notifications delivered in the past 24 hours to all CometD clients
`DailyDurableStreamingApiEvents`	PushTopic event notifications delivered in the past 24 hours to all CometD clients
`DurableStreamingApiConcurrentClients`	Concurrent CometD clients (subscribers) across all channels and for all event types
Streaming API (API version 36.0 and earlier)
`DailyGenericStreamingApiEvents`	Generic events notifications delivered in the past 24 hours to all CometD clients
`DailyStreamingApiEvents`	PushTopic event notifications delivered in the past 24 hours to all CometD clients
