// 初始化SDK
const sdk = new TencentESignSDK({
    appId: 'your_app_id',
    privateKey: 'your_private_key'
});

// 创建合同
sdk.createContract({
    contractName: 'Example Contract',
    contractContent: 'This is the content of the contract...',
    signers: [{
        name: 'Signer 1',
        idCard: '123456789012345678',
        mobile: '13800138000'
    }]
}).then(contract => {
    // 发送签署邀请
    return sdk.sendSignInvitation(contract.contractId, 'signer_email@example.com');
}).then(() => {
    console.log('Contract sent successfully!');
}).catch(error => {
    console.error('Error:', error);
});
