If you want to promote your inventory using retargeting ads (for example, dynamic ads), create a data feed:

1. Choose a supported file format for the feed. This is where you'll enter the values needed for the feed. You can upload these file formats into your feed:
   • CSV/TSV: Comma-separated value (CSV) or tab-separated value (TSV). Can be used with most spreadsheet programs.
   • XML (ATOM/RSS): Format typically generated by automated feed provider systems or web servers.
2. Create a data feed file with the required item information. Learn more about setting up a data feed for all catalogue types.
3. Save your file.
4. (Optional) Test your feed before you upload it to Facebook using the product feed debugger tool. For CSV/TSV files, copy the first row (column header row) and a few products; for XML, copy the XML with a few products, paste the lines into the text area, then click Validate. Make sure that you click the drop-down menu first to select the type of products in your feed before you validate them.

Upload a data feed

To add a data feed to your catalogue:

1. Go to Catalogue Manager.
2. Choose the catalogue you want to update.
3. Click Data sources.
4. Click Add Data Source.
5. Click Use Data Feeds and click Next.
6. Choose Upload once or Set a schedule. Learn more about uploading your data feed in Catalogue Manager.
7. Enter a name for your data feed.
8. Select the default currency for the data feed. Your catalogue uses the default currency when the prices in your data feed file don't include an ISO currency code (for example: 10 USD instead of $10.00). You can update the default currency at any time in your data feed settings.

If you don't have a data feed, or you're unable to create a data feed, you can add items to your catalogue manually using a form. This option is only available for advertisers with e-commerce catalogues.

1. Go to Catalogue Manager.
2. Choose the catalogue you want to update.
3. Click Data sources.
4. Click Add Data Source.
5. Click Add Manually.
6. Fill in all fields to add a new product item:
• The Name of your product should be under 26 characters (including spaces) for it to be displayed without being cropped.
• The Price is set to USD by default. After the first time you change the currency, your selection will be remembered.
• (Optional) Add a Content ID if you want to run dynamic ads. This is an optional field. The Content ID needs to match a pixel event on your website and needs to be associated to the catalogue before you can run the ad.
7. Click Add product to save. To add more items, click Add Another Product and repeat the process.

If a merchant platform hosts your inventory, you can upload inventory from the platform using Catalogue Manager. You don't need to create another data feed when you use this method. For detailed instructions on how to use merchant platforms with Catalogue Manager, select one of the following links below:

• Shopify
• WooCommerce
• BigCommerce
• Magento
• Google

If you update your inventory frequently, you can use the Facebook pixel to automatically update the products in your catalogue each time someone visits them. When someone visits your website and interacts with a product, this adds the product to your catalogue. This option is only available for advertisers with e-commerce catalogues.

Before you begin, make sure that you:

1. Install the Facebook pixel on your website and choose the right events that you want to track.
2. Install required microdata tags on your website for each item that you want to add to your catalogue.
3. Ensure that a pixel fire has been sent from your website in the last seven days. Bear in mind that pixel fires are dependent on website traffic to your page, so it may take some time.

To add items to your catalogue using a pixel:

1. Go to Catalogue Manager.
2. Choose the catalogue you want to update.
3. Click Data sources.
4. Click Add Data Source.
5. Click Connect Facebook pixels as your upload method.

6. Choose the pixel that you want to associate with the catalogue. The ads you create with your catalogue automatically show items based on customer behaviour on your websites.

   Note: If the pixel doesn't meet the requirements, you won't be able to select the pixel until those requirements are met.
7. Select Next. Your items are then uploaded to your catalogue. Bear in mind that it may take some time to upload your items. You can continue to work in Catalogue Manager as your items are being uploaded to your catalogue.
8. Click Done.
