# API Usage

> How Benji uses integration APIs to process transactions and determine eligibility

Benji uses information about loyalty customers, their status, and their payment transactions in order to power the automatic processing and eligibility determination for each transaction.

## API Access

Not all data is present in webhooks provided by our integrators, so we correlate that information with loyalty customers using their APIs.

Benji uses the following APIs:

* **Payments**: Correlate payments with orders and customers.
* **Loyalty Customers**: Ensure we can connect the customer to their loyalty accounts for our suite of partners.
* **Orders**: Analyze the orders placed by customers to determine eligibility for rewards.

> **Note:** This data applies to all supported integrations (e.g., Square, Stripe). See [Integration Overview](./overview) for platform-specific details.

## Event Payload Examples

```json theme={null}
{
  "type": "purchase",
  "customer_id": "12345",
  "amount": 100.00,
  "items": [
    { "sku": "A1", "qty": 2 }
  ]
}
```
