How many requests can be sent in a single batch using the Batching REST resource?

The correct answer reflects Salesforce's limitation on the number of requests that can be processed in a single batch using the Batching REST resource, which is set at 25 requests. This batching capability allows for efficient use of API calls, as it enables developers to bundle several discrete operations into a single network request.

In the context of data operations within Salesforce, particularly when using the REST API, batching can significantly enhance performance and reduce latency by minimizing the overhead associated with multiple round-trip requests. By applying this batching constraint, Salesforce also manages system resources effectively, ensuring that the API remains responsive and stable under load.

Selecting this specific value of 25 requests is crucial for Salesforce integration architectures because it encourages developers to design workflows that optimize API usage while adhering to company guidelines and best practices. Understanding this limit not only aids in efficient coding and resource management but also improves the overall integration process with Salesforce services.
