Salesforce accounts are subject to a maximum number of API calls that can be made against Salesforce's servers in any 24-hour period. Calls will be blocked until usage for the preceding 24 hours drops below the limit.
When Geckoboard performs a widget refresh it polls Salesforce for the current status of that report. This polling activity consumes up to 3 API calls. If you have multiple widgets powered by the same report Geckoboard caches the data to avoid wasting API calls. For example, if you have 10 widgets powered by the same report, we'll only make 3 calls, rather than 30.
Ways to prevent exceeding your API request limit
Reduce how often Salesforce widgets update
Edit your Salesforce widgets to change the refresh rates. It'll also let you know how many API calls the widget will use per day.
If you have a widget set up to visualize a report that updates only twice per day, you're better off refreshing only every 2.5 hours.
Purchase extra API calls
If you're still exceeding your API request quota it's possible you need a higher limit. For more information, contact your Salesforce account representative.
