Connect Meta catalog and Pixel

Connecting Meta gives you two things at once: a product catalog for Facebook and Instagram Shopping, and a Pixel + Conversions API setup for tracking. Both share one authorization, so you only connect once.

Connect your Meta account

Go to Settings → Meta → Connection.
Select Connect Meta. This opens Facebook Login for Business in a popup.
Grant access to the Business Manager that owns (or should own) your catalog and Pixel.

Máximo stores one Meta authorization per store and uses it for both Meta Catalog and Meta Pixel + CAPI. Reconnecting either one re-authorizes both. If a token expires, the Connection tab flags it and offers Reconnect Meta.

Choose or create a catalog

On Settings → Meta → Catalog, pick a commerce catalog from the accounts your Meta login can reach, or select Create new catalog to have Máximo create one for you. Only commerce catalogs can hold products, non-commerce catalogs show up in the picker but can’t be selected.

By default, product variants that share a product are grouped under one item_group_id so Meta treats them as a single product with variants. You can turn this off under Variant grouping if you’d rather sync each variant separately.

Once connected, set a sync schedule on the same tab, Máximo pushes your catalog to Meta automatically on that schedule, and you can trigger a sync on demand.

Product sets from your collections

Under Product sets, select Add collections to mirror chosen Shopify collections as Meta product sets. This lets you target a specific collection (a category, a sale, a seasonal drop) when building Advantage+ catalog ads, without maintaining a separate list in Meta.

Advantage+ catalog ads

Meta automatically generates video ad creatives from your product images and any product videos synced from Shopify. This is on by default for every catalog Máximo connects, there’s nothing to configure.

Turn on the Pixel

On Settings → Meta → Pixel, either choose a Pixel from the list Máximo found in your connected Meta account, or enter a Pixel ID manually if you manage it elsewhere. Saving a Pixel for the first time also enables it.

Once a Pixel is configured, use Enable/Disable to control whether it loads on your storefront. Máximo also offers to Link pixel to catalog, which registers the Pixel as an event source on your catalog, this is what lets Meta match Pixel conversions back to catalog products for Advantage+ Catalog Ads.

Enable the storefront embed

The Pixel only fires once you turn on the theme app embed:

In Shopify admin, go to Online Store → Themes → Customize.
Open App embeds.
Enable Máximo Pixels.

This single embed covers Meta, TikTok, Google, and Pinterest, you only need to turn it on once, even if you connect more than one of these destinations.
