# For API Integration (Merchants)

You can associate a bank account with orders or payment links in two ways:

## Option 1: Using an Existing Bank Account ID

If the customer already has a registered bank account, reference it by ID:

## Create Order

### API Endpoint


```curl
POST https://api.glomopay.com/api/v1/orders
```

### Request


```curl
{
  "customer_id": "cust_E602dMzgjpDC",
  "amount": 10000,
  "currency": "USD",
  "purpose_code": "P1401",
  "bank_account_id": "ba_xyz123"
}
```

## Option 2: Providing Bank Account Details Inline

If you have the customer's bank account details, provide them directly:

## Create Order
