What can the Salesforce operation action return?

The Salesforce operation action can return zero to many object records, which means it is flexible in handling the results of a query. This is particularly useful when dealing with Salesforce data, as you might execute a query that could potentially match multiple records, such as retrieving all contacts related to a specific account or all opportunities within a certain timeframe.

This functionality allows developers to efficiently handle scenarios where they do not know in advance how many records will match their criteria. It provides a capacity to fetch either no results, if the query doesn't match any records, or multiple records, should there be any that fit the defined parameters.

The ability to return multiple records is essential for integrating and manipulating data effectively within applications that interface with Salesforce, making it a powerful tool for developers building data-driven solutions.
