# Introduction

The Reward Calendars API service allows you to create and manage reward calendar offers in your web store. Reward calendars are 7-day calendar popup offers that show players the upcoming rewards of the week, and let them collect the current day's reward.

Learn more about [Reward Calendar offers](/../../guides/webstore/offers/reward-calendars/about-reward-calendars).

With the Reward Calendars API service, you can:

* [Create a new reward calendar offer](./create-reward-calendar).
* [Update an existing reward calendar offer](./update-reward-calendar).
* [Retrieve one or more reward calendar offers](./get-reward-calendar).
* [Retrieve all reward calendar offers](../get-offers).
* [Delete a reward calendar offer](./delete-reward-calendar).

## Before you begin

It’s important to note the following points before starting to code:

* The `productsSequence`  array must include seven objects representing the reward tiles for each configured week. You can configure one to 10 weeks, so the sequence must be a multiple of 7 and a maximum of 70 items. The main reward is every seventh index, such as 7, 14, and 21. All other indexes are sub rewards.

* If you set `rewardCollectionBehavior` to `ForcePlayerToCollect`, players must collect the available reward when the popup opens. Because collection can't be deferred, the collectible badge isn't shown.

## Terminology

These terms define how the Reward Calendar behaves for players:

* **Reset behavior:** Determines how player progress resets after a missed day, either to Week 1, Day 1, or to Day 1 of the current week.
* **Popup trigger:** Determines whether the popup opens automatically when a reward becomes available, or only after the player clicks the badge.
* **Reward collection behavior:** Determines whether players must collect the reward immediately, or can close the popup and collect later that day.
* **Start over:** Determines whether the calendar restarts after players complete all configured weeks.
