# Marketing & Offers

{% hint style="info" %}
Implementation is **OPTIONAL**
{% endhint %}

### General flow

* Smarts shows marketing offers inside app after client log in to store.
* Client will tap to add the offer to shopping cart
* Client can accept more offers during the shopping process (tab will be available)
* **COMING SOON !** Cross-sale offer can be send along with product data which will be displayed after product has been added to shopping cart.

### Configuration

**Implement required SDK methods for offers and marketing.** There is no additional configuration needed at the moment.

### Implementation

You only need to create a new class, implement **`OfferAdapter`** interface and fill all required methods.  API endpoints for marketing are created automatically and secured with token. 

It is important to add `@Component` annotation on top of the class. There is no restriction for class name or location in your project. Our SDK will find your implementation based on the interface (DI).

```java
import ee.smarts.common.v1.Entities.offer.Offer;
import ee.smarts.common.v1.requests.OfferSearchRequest;
import ee.smarts.starter.adapter.OfferAdapter;
import org.springframework.stereotype.Component;
import java.util.List;

@Component
public class OfferServiceImpl implements OfferAdapter {

    @Override
    public List<Offer> searchOffers(OfferSearchRequest request) {
        // implement this method
        return null;
    }
}
```
