Offline Transaction File Submission Implementation Guide {#batch-about-guide-java} ================================================================================== 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 offline transaction requests to `Cybersource` in CSV-formatted batch files. Batch files can be uploaded to `Cybersource` using the Simple Order API with Java authentication. Batch files can also be submitted to `Cybersource` at the `Business Center`. The Offline Transaction File Submission system ingests batched payment requests composed of fields from the `Cybersource` Simple Order API. 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: Simple Order and SCMP API Field Mapping](/docs/cybs/en-us/batch/user/all/so/batch-upload/batch-java-api-field-mapping.md "").
