# Onboarding milestones: donations with the Charitips API

> A SaaS turns its setup checklist into donations: each step completed unlocks 0,20 € to 1 €, paid by the vendor. The new user picks the charity once, at the first milestone.

- **Use case**: [Progress and tiers](https://www.charitips.com/docs/use-cases/progress-and-tiers.md)
- **Sector**: Software and apps
- **Who pays**: Your company
- **What starts the donation**: A customer action
- **Example**: 0,20 € to 1 € per milestone reached
- **Calls**: [`POST /v1/charities-selections`](https://www.charitips.com/docs/api-reference/create-charities-selection.md), [`POST /v1/campaigns`](https://www.charitips.com/docs/api-reference/create-campaign.md), [`POST /v1/campaigns/{campaignId}/activate`](https://www.charitips.com/docs/api-reference/activate-campaign.md), [`POST /v1/donations`](https://www.charitips.com/docs/api-reference/create-donation.md), [`POST /v1/donations/{donationId}/claim`](https://www.charitips.com/docs/api-reference/claim-donation.md)
- **Webhooks**: `donation_create`, `donation_update`

## How it works

The screens of the demo in order, with the calls your server makes at each one.

### 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 software",
    "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 software",
    "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

### 1. At the first step

- Button: Complete the step

**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": 20,
    "uniqueExternalId": "kpi_5521_first_project",
    "externalId": "user_5521"
  }
  ```

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

### 2. When the charity is chosen

- The customer picks a charity from your selection.
- Button: Choose the charity

**Your server calls:**

- [`POST /v1/donations/{donationId}/claim`](https://www.charitips.com/docs/api-reference/claim-donation.md) Claim a donation: donationId from the create-donation response

  ```json
  {
    "charityId": "<charityId>"
  }
  ```

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

### 3. At the next step

- Button: Complete the step

**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": 50,
    "uniqueExternalId": "kpi_5521_first_invite",
    "externalId": "user_5521",
    "charityId": "<charityId>"
  }
  ```

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