The Sell Feed API lets sellers upload and download feed files and reports, and create schedules. Both upload and download feed files are processed asynchronously by eBay. The status of all upload and download tasks are tracked with a unique 'task ID'. Each report can be customized with date ranges and other filter criteria.

Technical overview

This API contains the following resources:

  • order_task - Create an order download task with filter criteria related to order and retrieve the status and details of a specific order task or a group of order tasks.
  • inventory_task - Create an inventory upload or download task with filter criteria related to inventory, and retrieve the status and details of a specific inventory task or a group of inventory tasks.
  • schedule - Create a schedule for the feed API resources. A schedule generates reports periodically for a specified feedType. Schedules are based off templates that define the parameters used such as feed type.
  • task - Create an upload or download task without filter criteria and retrieve the status and details of a specific task or a group of tasks. Whether it is a download or upload task depends on the feed_type specified.
  • customer_service_metric_task - Create a customer service metrics download task with filter criteria. This task can also retrieve the status and details of a specific customer service metrics task or group of tasks.

Business use cases

The Sell Feed API supports the following use cases. See the LMS Feed API Guide for additional information.

By using the order_task methods, you can generate an Order Report that shows detailed information on all unacknowledged orders. For details, see Overview of order report flow.

Acknowledge fulfilled orders with an Order Ack upload file

You can acknowledge orders you have received and are processing or fulfilling by uploading an order acknowledgment file. After this file has been processed, only the unacknowledged orders will be returned in the next order report. For details, see Submitting an order acknowledgment file.

Download an Active Inventory Report

Through the inventory_task methods, you can create an Active Inventory Report that shows price and quantity information for all active listings. For details, see Overview of active inventory report flow.

Download Customer Service Metrics reports

Through the customer_service_metric_task methods, you can create a report download task and retrieve a list of transactions that affect performance for given evaluation type, service metric type. Other filters can also be specified. You can search the returned list of transactions by applying a data range filter for the request creation date. For details, see Customer Service Metrics Report.

Create schedules

Through the schedule methods, you can create a schedule, which is a subscription to a specified schedule template. A schedule returns a report for the feed_type specified by the template. When creating the schedule, specify the template with the feed type and any other parameters needed for your schedule. You can also specify a preferred trigger hour, day of the week, or day of the month. For details, see Creating Schedules.
