You cannot create an Org Limit, since Salesforce sets the allocations for your edition and license count. What you can configure is monitoring, so the org warns you before a ceiling is reached. The main tool is an API Usage notification, set up in Setup under Company Information.
- Open API usage notifications
In Setup, go to Company Information, then find the API Usage Notifications related area, or search Setup for API Usage Notifications directly.
- Create a notification
Add a new notification, choose the recipient user, and set the threshold percentage of the Daily API Request Limit you want to be warned at.
- Set the interval
Choose how frequently the alert repeats while the threshold stays breached, then save. Add a second, higher-threshold notification for escalating urgency.
- Cross-check with the Limits API
For automated reactions, call /services/data/vXX.0/limits on a schedule and alert when Remaining for DailyApiRequests, DataStorageMB, or FileStorageMB drops too low.
The user who receives the threshold email. Pick a monitored team alias or an admin who acts on alerts, not a personal inbox that may go unwatched.
The share of the Daily API Request Limit that triggers the email, for example 50, 80, or 90 percent. Lower thresholds give earlier warning and more lead time to react.
How often a breaching threshold re-sends. Common pairings are 50 percent every 24 hours, 80 percent every four hours, and 90 percent every hour for tightening urgency.
Not a notification setting, but the Storage Usage page in Setup is where you confirm data and file storage headroom and see which objects consume the most space.
- API Usage notifications cover the daily API request count, not storage; watch storage separately on the Storage Usage page or via DataStorageMB in the Limits API.
- The Limits API values lag real consumption by up to about five minutes, so treat them as near-real-time, not exact gating thresholds.
- The daily API limit is a rolling 24-hour window, not a fixed midnight reset, so a spike can keep you over the line longer than you expect.
- Raising the ceiling usually means buying capacity or licenses; tune integration design first, because batching often removes the need entirely.
