Supported channels

Every plan can send feeds to all channels below. When you create a feed, you choose Direct channel connection (API) or Export a data file.

• Direct channel connection (API): you log in to your channel account and Omega Feed sends products directly. You can view product approval status and fix issues in the app. Real-time price and stock updates work only with this option (Pro and Max).
• Export a data file: Omega Feed builds a file and gives you a feed URL. The channel fetches that URL on its own schedule. Issues must be fixed on the channel's dashboard.
• The first format in each row is the default for a new feed. You can change it in the feed's settings.

Feed attributes

An attribute is one piece of product data a channel reads, such as title or price. You see them on the Attributes tab of each feed. Click Required to see only the ones your channel needs.

The table shows the main attributes, what fills them by default and which channels the app marks as required.

• Some channels show a different name for the same attribute. Facebook and Tiktok call ID Content ID. OpenAI uses Item ID, Product URL and Image URL.
• On the Attributes tab, attributes are grouped into Essential fields, Media, Pricing, Identifiers, Categorization, Shipping, Clothing & shoes, Product details and Ads & campaigns. Google API feeds also have Energy & certifications.
• You can fill an attribute from a product field, a variant field, a Shopify metafield or a fixed value. Changing the mapping needs Pro or Max. See Map attributes and Plan limits.

Rule operators

Rules on the Rules page include, exclude or change products across your feeds. Each rule has up to 20 conditions, matched with all or any.

Include and Exclude rules check these fields: Title, Description, Image, Vendor, Product type, Tags, Collection, SKU, Barcode, Price, Compare-at price and Weight. Price and Compare-at price use your store currency.

• Include and Exclude rules ignore upper and lower case and accents. "T-Shirt" equals "t-shirt".
• A description that holds only HTML and no text counts as empty.
• For Collection, the value is checked against the title of every collection the product is in.

Set attribute rules use the same operators as attribute mapping: Contains, Equals, Starts with, Ends with, Greater than, Less than and Any in.

• Contains ignores upper and lower case. Equals, Starts with and Ends with are case-sensitive.
• Any in matches when at least one item of a list field, such as tags, is in your comma-separated list. Example: refurbished, used.
• Any plan can save a Set attribute rule. Only Pro and Max apply it to feeds.

Limits: 50 rules of each type (Include, Exclude, Set attribute), 20 conditions per rule, 255 characters per value. On Free, rules check only your 100 newest products. See Feed rules.
