Recently a Salesforce org's integraon failed because it exceeded the number of allowed API calls in a 24-hour period. The integraon handles a near real-me, complex inseron of data into Salesforce. The flow of data is as follows: The integraon looks up Contact records with a given email address and, if found, the integraon adds a Task to the first matching Contact it finds. If a match is not found, the integraon looks up Lead records with a given email address and, if found, the integraon adds a Task to the first matching Lead it finds.
