Offline Transaction File Submission Implementation Guide {#batch-about-guide-rest}
==================================================================================

This section describes how to use this guide and where to find further information.

Audience and Purpose
:
This guide is written for merchants who want to submit multiple payment transaction requests to `Cybersource` for offline transaction processing. CSV files that contain transaction requests can be uploaded in two ways: at the `Cybersource` `Business Center` or by using the `Cybersource` REST API

    > IMPORTANT  
    > The Offline Transaction File Submission system ingests batched payment requests composed of fields from the Cybersource Simple Order API. The Simple Order API fields you use to create transaction requests in a batch file are described in [Reference: Request Fields for Batch Files](/docs/cybs/en-us/batch/user/all/rest/batch-upload/batch-ref-fields.md "").  
    > If you normally use the SCMP API to request individual transactions, you need to know which Simple Order API fields correspond to the SCMP API fields with which you are familiar. Mapping information is provided in [Reference: Mapping SCMP API Field Names to Simple Order Names](/docs/cybs/en-us/batch/user/all/rest/batch-upload/batch-ref-scmp-so.md "").
