# Demo: A campaign for a date: Happy hour

> A restaurant's charity happy hour puts 5 % of each order into the evening's pot for a named charity. At 8 pm, the till sends the pot as one donation; the restaurant pays.

One variant of **A campaign for a date**, in Hotels and restaurants: 5 % of the evening's happy-hour sales.

A made-up site, order.your-restaurant.example, walked through screen by screen with the Charitips API calls the product makes at each step. Rebuild it in your own project to start from a working flow.

The full guide, with edge cases: https://www.charitips.com/docs/use-cases/campaign-for-a-date.md.

**Once, before the first customer:**

- [`POST /v1/charities-selections`](https://www.charitips.com/docs/api-reference/create-charities-selection.md) Create a charities selection: once: the charities you offer, from the catalog

  ```json
  {
    "name": "Your restaurant",
    "charityIds": [
      "<charityId>"
    ]
  }
  ```
- [`POST /v1/campaigns`](https://www.charitips.com/docs/api-reference/create-campaign.md) Create a campaign: once: the campaign the donations go to

  ```json
  {
    "name": "Your restaurant",
    "charitiesSelectionId": "<charitiesSelectionId>",
    "type": "PERMANENT",
    "amountType": "FREE_AMOUNT"
  }
  ```
- [`POST /v1/campaigns/{campaignId}/activate`](https://www.charitips.com/docs/api-reference/activate-campaign.md) Activate a campaign: once: the campaign starts taking donations

## Screens and calls

### 1. With each order

- Button: Send the order

No call: this screen only shows the result.

### 2. At the end of happy hour

- Button: Skip to 8 pm

**Your server calls:**

- [`POST /v1/donations`](https://www.charitips.com/docs/api-reference/create-donation.md) Create a donation: from your server, when it happens; amount in cents

  ```json
  {
    "campaignId": "<campaignId>",
    "amount": 6280,
    "uniqueExternalId": "happy_hour_evening_412",
    "charityId": "<charityId>"
  }
  ```
- [`GET /v1/campaigns/{campaignId}/metrics`](https://www.charitips.com/docs/api-reference/get-campaign-metrics.md) Get campaign metrics: what the campaign has received so far, for the gauge

Charitips then sends the `donation_create` webhook to your endpoint.

## Clone it with a coding agent

```prompt
Clone the Charitips demo "A campaign for a date: Happy hour" into this project. Read https://www.charitips.com/docs/demos/moment/happy-hour.md: it lists each screen and the Charitips API calls behind it. Build the same flow in this codebase, on the sandbox (https://api.sandbox.charitips.com), with my client id and secret read from environment variables, and follow the rules of https://www.charitips.com/docs/skill.md. Make every API call from the server, never from the browser. When it works, show me each call and its response.
