The PATCH import method is specifically designed for modifying existing records within the destination application based on the current data provided in the import. When using PATCH, it doesn't create new records but instead updates existing ones according to the identifiers or keys provided in the data. This is particularly useful when a user wants to ensure that specific fields or attributes of a record are updated without affecting the rest of the record that remains unchanged.

In contrast, other methods focus on either creating new records, deleting existing ones, or solely transferring files. The ability of PATCH to precisely target updates makes it essential in scenarios where maintaining the integrity and accuracy of existing data is critical.
