# Config 1: Standard Nested YAML

## Scenario
Testing standard nested YAML structure dengan **multiple root keys** dan **arrays of objects** dengan properties kompleks.

## Use Case
Configuration file untuk multiple billers dengan struktur yang sama, di mana setiap biller punya API credentials dan HTTP headers configuration.

---

## Input: CONFIG1.yaml

```yaml
fundtastic:
  ApiSecret: secret_fundtastic_123
  TrxAuthMethod: basic
  TrxSignKey: X-Signature
  TrxSignAlgorithm: HMACSHA256(hex)/ApiSecret
  endpoint: https://api.fundtastic.com/v1
  timeout: 30000
  headers:
    - name: Content-Type
      type: LITERAL
      value: application/json
    - name: X-Timestamp
      type: DEFAULT
    - name: X-Signature
      type: PATH
      value: Environment.Variables.Signature

itm:
  ApiSecret: secret_itm_456
  TrxAuthMethod: bearer
  TrxSignKey: Authorization
  endpoint: https://api.itm.com/payment
  headers:
    - name: Authorization
      type: LITERAL
      value: Bearer token123
    - name: Content-Type
      value: application/json
```

## Output: hasilParseConfig1.json

      {
        "name": "Content-Type",
        "type": "LITERAL",

        "value": "application/json"
      }
    ]
  }
}
```

## ESQL Usage

```esql
-- Ambil config untuk biller 'fundtastic'
DECLARE billerConfig REFERENCE TO Environment.Variables;
DECLARE success BOOLEAN;

CALL ACE_LIB.getConfig(
    'BILLER_CONFIG_fundtastic',
    'fundtastic',
    '/path/to/CONFIG1.yaml',
    '600',
    billerConfig
) INTO success;

IF success THEN
    -- Akses scalar values
    DECLARE apiSecret CHARACTER billerConfig.ApiSecret;
    DECLARE endpoint CHARACTER billerConfig.endpoint;
    DECLARE timeout CHARACTER billerConfig.timeout;
    
    -- Loop headers array
    DECLARE headerRef REFERENCE TO billerConfig.headers[1];
    WHILE LASTMOVE(headerRef) DO
        DECLARE headerName CHARACTER headerRef.name;
        DECLARE headerType CHARACTER headerRef.type;
        DECLARE headerValue CHARACTER COALESCE(headerRef.value, '');
        
        -- Process header...
        
        MOVE headerRef NEXTSIBLING;
    END WHILE;
END IF;
```

## Key Features Tested

✅ Multiple root keys (`fundtastic`, `itm`)  
✅ Nested scalar values  
✅ Arrays of objects with multiple properties  
✅ Optional properties in array items (some headers have `value`, some don't)  
✅ Dynamic key selection (dapat pilih `fundtastic` atau `itm`)
