What methods exist for checking your API limit usage on Salesforce?

The option regarding "Setup > Monitor > System Overview > API Usage" is correct because this method provides direct access to the API usage metrics through the Salesforce Setup interface. Within the System Overview section, users can find real-time statistics about their API calls utilization. This area allows administrators to monitor current usage, making it easy to identify whether they are nearing their limits, which is crucial for maintaining healthy integration operations.

Salesforce sets strict limitations on API calls to ensure fair resource distribution among its many users, making it essential for organizations to keep track of their usage. The System Overview provides a straightforward visualization of how much API capacity has been consumed and how much is left, allowing organizations to plan accordingly.

While the other methods mentioned can serve helpful purposes in monitoring and managing resources, they may not provide the same level of detail or direct access to API usage data as the System Overview within the Setup area. It ensures that administrators can promptly identify and address any potential issues regarding API limits.
