What is the default batch size limit when using the SOAP API?

The default batch size limit when using the SOAP API is 500. This limit is significant because it defines how many records can be included in a single API request when processing data. By setting a batch size limit, Salesforce optimizes server resources and helps ensure efficient data handling during operations like insert, update, or delete actions.

Utilizing a batch size of 500 strikes a balance between reducing the number of API calls and minimizing the risk of hitting governor limits, while still ensuring that the transactions are processed efficiently.

In scenarios where large amounts of data are being handled, adhering to this default size may prevent errors related to timeouts or limits on processing, ensuring a smoother integration experience for developers working with the Salesforce platform. Understanding this limit helps architects and developers design more efficient integrations and manage data more effectively within Salesforce's ecosystem.
