# Objects

Every SDK method returns plain JavaScript objects. There are two of them:

* [Recommendation](/client-api/objects/recommendation.md) — a newsletter your readers can subscribe to.
* [Offer](/client-api/objects/offer.md) — a sponsored offer your readers can claim.

Objects are meant to be displayed right away and acted on immediately. Never cache or store them for later use — see [Errors & Warnings](/client-api/errors-and-warnings.md).
