Processing overrides are additional data fields to be used only for processing. Provided values will take precedence over any similar fields(e.g. processingOverrides.customerEmail takes precedence over the vaulted customer's email address).
However, these values will not update any similar fields (e.g. providing processingOverrides.customerEmail will not update a vaulted customer's email address). These values are not returned in responses.
