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?

1. A. Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
2. B. write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
3. C. Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.
4. D. Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
