Question67: Recently a Salesforce org's integration failed because it exceeded the number of allowed API calls in a
24-hour period. The integration handles a near real-time, complex insertion of data into Salesforce. The flow of data is as follows: The integration looks up Contact records with a given email address and, if found, the integration adds a Task to the first matching Contact it finds.
