# Introduction

The Reward Calendar Designs API allows you to create and manage designs for reward calendar offers. Reward calendars are 7-day calendars that display one reward per day. Days 1-6 are sub rewards displayed as regular calendar days, while Day 7 is the main reward displayed as a larger, wider featured tile.

With this API, you can:

* [Create a reward calendar design](./create-reward-calendar-design).
* [Update a reward calendar design](./update-reward-calendar-design).
* [Delete a reward calendar design](./delete-reward-calendar-design).
