# Summary

XCover Elements handles the front-end presentation of offers to your customers. When a customer views protection products, XCover Elements creates offers automatically — no backend integration is needed for this step.

Once a customer has selected or declined a protection product, your backend server integrates directly with the **XCover API** to complete the transaction. This includes:

* **Confirming an offer** the customer has accepted
* **Opting out** of an offer the customer has declined

**Connecting frontend to backend:** The offer response from XCover Elements contains a `provider_reference` field. Use the IDs from `provider_reference` when making requests to the XCover API — these map the frontend offer to the corresponding XCover resource.

**Authentication:** The XCover API uses HMAC signature authentication for all server-to-server requests.

You can use the HTML Demo under Client Integration Examples to display an example frontend widget, and the [Postman Collection](https://web.postman.co/workspace/%255BGitBook%255D-XCover-Elements-Demo~4aca8c38-22e6-4762-8cc7-0be5c3ed0ec7/collection/9582676-47676b6b-2078-40ce-82c7-7f269d1c2020) for the same demo partner to see example booking requests against the XCover API.

**Note: The Postman collection requires access. Please liase with your key account manager to request access.**
