Omnichannel Ads

Updated: May 21, 2026

Omnichannel ads is a new optimization solution that lets you drive in-store and website sales using one sales campaign. The solution also includes new store location ad features to make shoppers aware of their nearest store locations.

Omnichannel ad setup is only officially supported in the Meta Ads Manager UI for advertisers, who can also use Marketing APIs for campaign setup and creation.

The following are the API integrations needed to create omnichannel campaigns, ad sets and ads.

Prerequisites

App permission

Apps should have the following permissions:

• ads_management
• ads_read

More detailed information on permissions and access can be found here.

Assets

Advertisers will need access to the following assets:

• AD_ACCOUNT_ID: ID of the ad account that ad campaigns, ad sets and ads will be associated with. More information here.
• PIXEL_ID: ID of a Meta Pixel. Used in promoted_object in ad set creation. More information on setup and permissions here⁠.
• OFFLINE_CONVERSION_DATASET_ID: ID of offline dataset. Used in promoted_object in ad set creation. More information on setup and permissions here.

Supported ad features

Omnichannel ads support many features of Meta ads, including:

• Advantage+ Catalog Ads⁠: automatically show people your most relevant products based on their interests, intent, and actions.
  • Omnichannel ads support Advantage+ Catalog ads at the campaign level. To opt-in, the field product_catalog_id is required in the promoted_object parameter in omnichannel ad campaign creation.
  • Besides e-commerce catalog, store-based local inventory (SBLI) catalog will also be available through the same setup flow. It will efficiently deliver relevant products available at a person's nearby store.
• Advantage+ Shopping Campaigns⁠: help you reach valuable audiences with less set up time and greater efficiency.
  • Omnichannel ads support ASC campaigns.
• Advantage+ Creative⁠: Optimize your images and videos to versions your audience is more likely to interact with.
  • Omnichannel ads support all kinds of A+C features
  • Store locations is the high performance Omnichannel A+C feature that helps drive offline conversions (Only available for non Advantage+ catalog ads). To opt-in, the field local_store_extension is required under degrees_of_freedom_spec in ad creative creation.

Omnichannel ad campaigns

To create a new omnichannel ad campaign, make a POST request to the /campaigns endpoint with the following parameters:

• name: The name of the campaign.
• objective: The objective of the campaign. Valid value is OUTCOME_SALES.
• status: The status of the campaign. Valid values are ACTIVE, PAUSED.
• promoted_object: Adding product_catalog_id will enable Advantage+ catalog ads.

Example:

curl -X POST \
https://graph.facebook.com/v20.0/act_<AD_ACCOUNT_ID>/campaigns \
-F 'name=My Omni campaign' \
-F 'objective=OUTCOME_SALES' \
-F 'status=ACTIVE' \
-F 'access_token=<ACCESS_TOKEN>'

Example for Advantage+ catalog ads:

curl -X POST \
https://graph.facebook.com/v20.0/act_<AD_ACCOUNT_ID>/campaigns \
-F 'name=My Omni campaign' \
-F 'objective=OUTCOME_SALES' \
-F 'promoted_object={"product_catalog_id":"<PRODUCT_CATALOG_ID>"}' \
-F 'status=ACTIVE' \
-F 'access_token=<ACCESS_TOKEN>'

Sample response

A successful response will return the ID of the newly created campaign.

Example:

{
  "id": "23845678901234567"
}

An unsuccessful response will return an error object with an explanation for the cause of the error.

Example:

{
    "error": {
"message": "Invalid parameter",
       "type": "OAuthException",
       "code": 100,
"is_transient": false
}

Error codes

The error codes that may be returned when creating an omnichannel ad campaign are the same error codes as in regular campaigns.

Omnichannel ad sets

To create a new omnichannel ad set, make a POST request to the /adsets endpoint with the following parameters:

• name: The name of the ad set.
• campaign_id: The ID of the campaign that the ad set belongs to.
• bid_strategy: The bid strategy for the ad set to suit your specific business goals.
• daily_budget: The daily budget for the ad set.
• attribution_spec: Conversion attribution spec used for attributing conversions for optimization. For omnichannel ads, only CLICK_THROUGH event_type with a 7 window_days and VIEW_THROUGH event_type with a 1 window_days are supported.
• promoted_object: The object your ad set is promoting across all its ads.
  • For an omnichannel ad set, promoted_object should have an omnichannel_object with Pixel and offline objects. PURCHASE is the only custom event type supported for omnichannel ad sets. Please review the example below.
    • If you are using a Meta Pixel to track website events and a separate dataset to track offline events, please send both Pixel ID and offline dataset ID (see example 1 below).
    • If you are using a single dataset to manage both your website and offline events, please use that dataset ID in both fields. (see example 2 below).
  • If you are creating Advantage+ catalog ads at ad campaign level, you'll also need to add product_set_id with the variation field set to PRODUCT_SET_AND_IN_STORE. See the example below.
    • You can also create a website, app, and in-store ad with Advantage+ catalog. You will need to add a product_set_id, a pixel_id that has an associated offline conversion dataset, an app ID, and a Pixel ID. You will also need to set the variation to PRODUCT_SET_WEBSITE_APP_AND_INSTORE. You do not need an omnichannel_object. See the example below.
• targeting: The targeting spec for the ad set.
• optimization_goal: OFFSITE_CONVERSIONS, which will optimize for people more likely to make a conversion in the site and store
• status: The status of the ad set. Valid values are ACTIVE, PAUSED

Example 1 - Using Meta Pixel to track website events and separate dataset to track offline events:

curl -X POST \
https://graph.facebook.com/v20.0/act_<AD_ACCOUNT_ID>/adsets \
-F 'name=My Omni Adset' \
-F 'campaign_id=<OMNI_CAMPAIGN_ID>' \
