Supplementary Feeds

Updated: Aug 3, 2023
Supplementary Feeds are used to modify existing data sources by providing either new or updated product field values. They can only be used to update existing products, but cannot add or remove products.
This document outlines the steps required to build an API integration to enable Supplementary Feeds support in your applications.
For more high-level information about Supplementary Feeds and use cases, please see these Help Center articles:

Requirements

Your application must have the catalog_management permission to create and read Supplementary Feeds.

Set Up Your Integration

Supplementary Feeds are files that represent a list of products. Under the hood, they map to existing products by attaching the Supplementary Feed to the primary data source that originally added the product.
A typical flow when doing an integration might look like this:
Step 1: Authenticate by using Facebook Login with the catalog_management permission
Step 2: Create a catalog selection page for the user to choose which catalog to supplement. List catalogs functionality can be found here:
Step 3: Find the available primary data sources which populate the catalog:
GET https://graph.facebook.com/<API_VERSION>/<CATALOG_ID>/data_sources?ingestion_source_type=PRIMARY

Step 4: Create a Supplementary Feed using the Feed API
  • Supplementary Feeds require the fields ingestion_source_type and primary_feed_ids to be populated.
  • The Supplementary Feed file requires all items to have the id attribute populated. Each id must match an existing product from the attached primary data source(s). Read more about Universal Basic Attributes and Category Specific Fields.
  • The relationship between Supplementary feeds and Primary data sources is 1-to-many. In other words, a Supplementary Feed can be attached to multiple Primary data sources, but primary data source may only have up to 1 Supplementary Feed attached.
Step 5: Handle Feed Upload Errors
