Create a catalog or feed

Omega can send your Shopify products to Meta in two ways:

• Catalog: Omega creates a catalog in your Meta Commerce Manager and keeps it updated for you. Pick this if your Facebook account has permission to manage catalogs in your Business account.
• Feed: Omega gives you a feed link, and you add that link to a catalog yourself in Commerce Manager. Pick this if you can't manage catalogs directly, or you want to control where the feed goes.

Both use the same setup form, so once you've created one, the other will feel familiar.

Create a catalog

Go to Catalog feed in Omega and click Create catalog. If your Facebook account isn't connected yet, Omega asks you to connect it first.

1. Business account, pixel and name

Your Business account is already selected. If you have more than one, pick the one the catalog should live in. It can't be changed after the catalog is created.

If your Business account has pixels added in Omega, click Click to choose a pixel and pick the pixel you use to track your store. This is what lets Meta match people's views and purchases to the products in your catalog, so use the same pixel you track with everywhere else. If you leave it empty, the catalog still syncs, but Meta can't measure your catalog match rate. Don't see the pixel option? Add your pixel to Omega first, then come back to this form.

Then give your catalog a name.

2. What to sync and what to exclude

Sync all products, or choose Selected products and pick collections, tags or specific products.

Under What to exclude, you can quickly leave out things that shouldn't be in ads:

• Products or variants priced $0 (only the $0 variants are skipped, the other variants of that product still sync)
• Products without images
• Gift cards
• Specific products, collections or tags

The number of products you've selected shows next to What to sync and updates as you change your choices.

3. How your variants show up on Meta

Choose how variants are sent:

• Each variant as a separate item: a T-shirt in Blue, Black and White becomes 3 items on Meta.
• Each product's variants as one group: the 3 colors are grouped under one product, so shoppers can switch between them.
• Only the first variant: only one item per product is sent.

Then choose the Item ID and Item title. Some combinations aren't available for a mode, and Omega tells you why right under the option. The Item ID matters for your catalog match rate, see Catalog match rate: keep your pixel and catalog in sync.

4. Price, link and images

• Which price to show: price and compare-at price, price only, or compare-at price only.
• Product link domain: Omega lists every domain connected to your store. Your primary domain in Shopify is selected by default, and you can switch to any other domain you like.
• Product images: send all product images or only the main image.

5. Category and sync schedule

Pick a Google/Facebook category. It helps Meta show your products to the right shoppers.

Under When to sync, choose weekly or daily, then the day and time. The time follows your store's time zone.

Options that need a higher plan show a plan badge next to them.

6. Check the Summary and Preview, then save

While you set things up, the right side of the form shows:

• Summary: your catalog name, how many products you selected and how many variants will sync, the next sync time, the product ID your pixel sends, and your catalog match rate status.

• Preview: a sample product showing how your items will look on Meta with your current settings. It's a sample, not one of your products.

If you're over your plan's product limit, the Summary shows how many will actually sync, with a link to upgrade.

When everything looks right, click Save. Omega creates the catalog in Commerce Manager and starts the first sync.

Create a feed

Click Create feed and fill in the same form. A feed doesn't need a Facebook account, Business account or pixel, so those parts aren't there.

After saving, copy the feed link and add it to a catalog in Commerce Manager. See Multiple Data Feeds for how to add it.

Omega can't see which catalog or pixel you use with a feed link, so the form doesn't check your catalog match rate for feeds. Make sure the pixel you use sends the same ID type as your feed's Item ID.

Edit a catalog or feed

Open it from the list to change your settings. A few things to know:

• The Business account can't be changed.
• If you're sending all product images, you can't switch to main image only, because Meta doesn't allow it after the first sync. Create a new catalog if you need a different setup.
• If you change the Item ID, the next sync sends items with the new IDs and removes the old ones once it's done. For a short while you may see both.

Need a resync after a big product launch or price change? Use Resync in the catalog's action menu.
