Which APIs can be used in batch processes?

The selection of Bulk API, SOAP API, and REST API as capable of being used in batch processes is well-founded due to their specific functionalities and capabilities.

The Bulk API is specifically designed for handling large volumes of data. It allows users to submit and process batches of records asynchronously, making it ideal for tasks that involve inserting, updating, or deleting significant amounts of data efficiently. Its capacity to process records in bulk operations is a key feature tailored for batch processing needs.

SOAP API is also a viable option for batch processes, particularly in scenarios where transactional integrity is critical. Although it is not as optimized for bulk data processing as the Bulk API, it still supports operations on multiple records through its various methods, enabling some level of batch capabilities depending on the use case.

REST API provides flexibility and can handle multiple records through its CRUD operations. While it is generally more oriented towards real-time interactions, its capability to process data in batches using multiple records in a single request adds to its functionality in batch processing scenarios, making it suitable for various integrations that need to handle multiple records at once.

The integration of these APIs allows for versatility in how batch processes are achieved within Salesforce, catering to the needs of different applications and integration scenarios. Thus, the answer correctly recognizes the
