File Transfer Services (FTS)

Business Overview

File Transfer Services (FTS) provide an endpoint for the customer to be used when working with files that are uploaded to and downloaded from the Merchandising Cloud Service Suite. These services are used by Merchandising and Sales Audit (RMFCS), Pricing (RPCS), Invoice Matching (ReIMCS), Allocation (RACS) and the Data Conversion tool. They allow you to manage uploading and downloading files to Oracle Cloud Infrastructure Object Storage, which is an internet-scale, high-performance storage platform that offers reliable and cost-efficient data durability.

For each customer environment, buckets, which are logical containers for storing objects, will be created in Object Storage. Any type of data, regardless of content type, is stored as an object. An object is composed of the object itself and metadata about the object. Any file uploaded through FTS to Object Storage has a retention period of 7 days before it is automatically purged.

The services use OAUTH 2.0 client credential authentication. Once authentication passes, the internal file transfer services that retrieve a pre-authenticated request (PAR) are called to upload and download files to Object Storage. The primary role of these services is to ensure that only valid external users can call the service by enforcing authorization policies.

List of services:

URL Prefix: https://rex.retail.<Region Name>.ocs.oraclecloud.com/<Customer Subnamespace>/RmsPlatformServices/services/private

The final URL will be the URL Prefix followed by the ReST URL path mentioned in each service description below.

To start uploading or downloading the files to/from Object Storage, storage prefixes should be registered first.

The table below shows the prefixes used by each of the solutions when calling the above listed services. By default, all the storage prefixes below will be registered automatically.

	RMFCS	RPCS	ReIMCS	RACS	Data Conversion
Incoming	/incoming		/incoming/reim	/incoming/alloc	/dataconversion/incoming
Outgoing	/outgoing				/dataconversion/outgoing
Reject	/reject			n/a	n/a
Downloaded	/downloaded		/downloaded/reim	/downloaded/alloc	n/a
Archive		n/a	n/a	n/a	n/a
