Create a Criteo Retail Media sponsored products campaign on a retailer network

Steps

1. Authenticate to the Criteo Retail Media API using the client_credentials OAuth 2.0 flow at api.criteo.com/oauth2/token with your Retail Media-scoped credentials (separate from Marketing Solutions credentials).
2. List available retailers and their account IDs via GET /retail-media/accounts to identify the retailer network(s) where you want to run campaigns.
3. Create a campaign under the brand account linked to the specific retailer account; set campaignType to SPONSORED_PRODUCTS and supply flight dates and a total or daily budget.
4. Create a line item under the campaign with keyword targeting or category targeting; for sponsored products, specify target product categories or explicit product IDs to control which products are promoted.
5. Attach product SKUs or catalog items to the line item; Criteo uses the retailer's own product catalog, so the SKUs must match identifiers in the retailer's catalog exactly.
6. Activate the campaign and monitor performance via the Retail Media reporting endpoint; metrics such as attributed revenue and ROAS are reported on a post-click basis with the retailer's attribution window.
