Sync a Criteo product catalog feed for dynamic retargeting via the Marketing Solutions API

Steps

1. Authenticate to the Criteo API using the client_credentials OAuth 2.0 flow to obtain a bearer token; use the token endpoint at api.criteo.com/oauth2/token.
2. Create or identify the catalog (dataset) in Criteo's system; for large catalogs (over one million products), use the Product Importer API for faster, more granular ingestion rather than file-based feeds.
3. Submit the product feed via the appropriate endpoint, including required fields: product ID, title, description, price, image_link, availability, and GTIN/MPN where applicable.
4. Schedule the feed import to run at least once daily to keep product availability and price data current; stale prices or out-of-stock items in the feed will still be served until the feed is refreshed.
5. Monitor the import job status and check the error report for rejected products; common rejection reasons include missing required fields and images that fail Criteo's aspect ratio requirements.
6. Once the catalog is approved and populated, associate it with your retargeting campaign in Campaign Manager or via the API's campaign-catalog linkage endpoint.
