How can I add Marketplace Offers to our Commercial Product Catalog?

You can either add them manually or use ListCatalogOffers API to retrieve partner offers which you have added to your Marketplace Product Catalog programmatically.

• When adding manually, you need to make sure that you configure Marketplace Offer ID and API Credentials in your Commercial Product Catalog which is required for provisioning the offer to a subscriber via generateActivationLink API. 
• You can also use ListCatalogOffers API to import partner offers into your Commercial Product Catalog or present them within your mobile or web application. You will receive everything you need to present the offer to your subscribers including Offer Price in your home country as well as Offer Headline and Description in your preferred language among the available translations in Marketplace.
