API Usage Notifications in Salesforce Setup can be used to notify if the API usage limit is going to exceed based on the Threshold configured.

Recipient will receive Salesforce API Usage Notifications when the Threshold is hit.

1. Go to API Usage Notifications.

2. Click the New button.

3. Select the system admin who should get the notification and save it. Once the threshold percentage is exceeded, a notification is sent once per the number of hours specified, until the limit is no longer exceeded.

Note:

Maximum 10 notification requests can be added.
