### Installments & credit methods

| Step | Endpoint |
|
||||
|------|----------|
|
||||
| 1. List methods | `GET /tenants/{domain}/store-loan-methods` → `{ enabled, items[] }` |
|
||||
| 2. Pick method | **If `items.length > 1`, ask the shopper which method** (name + image). If exactly one, auto-select. Never skip this when multiple exist. |
|
||||
| 3. Collect inputs | Purchase total (`totalValue` ≥ `minShoppingAmount`), credit amount (within `minAmount`–`maxAmount`, ≤ total), months from `returnMonthOptions` / slider with `returnMonthsStep` |
|
||||
| 4. Calculate | `POST /tenants/{domain}/store-loan-methods/calculate` with `{ methodId, totalValue, creditAmount, months }` |
|
||||
|
||||
```json
|

POST /tenants/{domain}/store-loan-methods/calculate
|
||||
{
|
||||
"methodId": "1",
|
||||
"totalValue": 5000000,

"creditAmount": 2000000,
|
||||
"months": 12
|
||||
}
|
||||
```
|
||||
|
||||
Response `{ method, plan }` — `plan` has `cashPayment`, `interestFee`, `totalRepay`, and `installments[]` (`index`, `dueDate`, `amount`). Fee = `round(credit × (interest/100) × (months/12))`.
|
||||
|
||||
Optional: `GET /tenants/{domain}/store-loan-methods/{methodId}` for a single method.
|

**Wrong:** calculating without a chosen `methodId`, or auto-picking the first method when several are listed.
