Optim Feed ‑ Facebook Catalog

I use this app to help me create Facebook catalog feeds for Ads and Instagram shop tagging. We used three other feed apps prior, and each could not handle the number of products because they used RSS feeds. This product uses an XML style feed and handles large inventories in seconds. We also needed customization to the app, and the developer responded and implemented our request app-wide in less than 24-hours. I highly recommend this product.
