A developer is trying to access org data from within a test class. Which sObject type requires the test class to have the (seeAllData=true) annotation?
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. If a match is not found, the integration looks up Lead records with a given email address and, if found, the integration adds a Task to the first matching Lead it finds. If a match is not found, the integration will create a Lead and a Task for that newly created Lead. What is one way in which the integration can stay near real-time, but not exceed the number of allowed API calls in a 24-hour period?
