## 5. Message Generation Code

### TypeScript Example

```typescript
import { generateISO20022Message } from '@comboflow/iso20022';

const generatePaymentInstruction = async (
  plan: Plan,
  compliance: ComplianceStatus,
  signature: string,
  dltTxHash: string,
  notaryProof: string
): Promise<string> => {
  const isoMessage = generateISO20022Message({
    messageType: 'pacs.008',
    groupHeader: {
      messageId: `MSG-${Date.now()}`,
      creationDateTime: new Date(),
      initiatingParty: {
        name: 'Example Corp Ltd.',
        lei: compliance.lei
      }
    },
    creditTransfer: {
      paymentId: {
        endToEndId: plan.planId,
        transactionId: `TX-${Date.now()}`
      },
      amount: {
        currency: 'EUR',
        value: 78000.00
      },
      debtor: {
        name: 'Example Corp Ltd.',
        lei: compliance.lei,
        account: {
          iban: 'DE89370400440532013000'
        }
      },
      creditor: {
        name: 'Beneficiary Corp',
        account: {
          iban: 'DE89370400440532013001'
        }
      },
      remittanceInformation: {
        unstructured: `Plan ID: ${plan.planId} | Combo Flow Execution`
      },
      supplementaryData: {
        planId: plan.planId,
        planHash: plan.planHash,
        compliance: {
          lei: compliance.lei,
          did: compliance.did,
          kyc: compliance.kyc,
          aml: compliance.aml
        },
        digitalSignature: {
          algorithm: 'ECDSA',
          signerAddress: plan.signerAddress,
          signatureValue: signature
        },
        dltReference: {
          chainId: 1,
          transactionHash: dltTxHash
        },
        notaryProof: {
          proofHash: notaryProof
        }
      }
    }
  });

  return isoMessage;
};
```
