Installation

npm install @digigov-oss/govcrm-rest-client

Quick Start

import {
    HttpGovCrmClient,
    StatusCode,
    ExternalSystemType,
    CustomerKeyType,
} from '@digigov-oss/govcrm-rest-client';
import axios from 'axios';

// Create HTTP reader using axios
const axiosReader = {
    get: async (url, config) => axios.get(url, config).then((r) => r.data),
    post: async (url, config) =>
        axios.post(url, config?.data, { headers: config?.headers }).then((r) => r.data),
};

// Initialize client
const client = new HttpGovCrmClient(axiosReader, {
    apiUrl: 'https://test.gsis.gr/esbpilot/govcrmRestService', // Pilot environment
    username: 'your-username',
    password: 'your-password',
});

// Update a case
const updateResponse = await client.updateCase({
    auditRecord: HttpGovCrmClient.createAuditRecordSync('1', 'MyOrg', 'PROT001'),
    govcrmCaseUpdateInputRecord: {
        govcrmSectorcode: '66797',
        govcrmExternalsystem: ExternalSystemType.EKEP,
        govcrmExternalticketnumber: 'CASE-123',
        govcrmStatusdetails: 'Case completed successfully',
        statuscode: StatusCode.SUCCESSFUL_COMPLETION,
        govcrmResponsereceivedon: HttpGovCrmClient.formatDate(new Date()),
        govcrmCustomerkey: CustomerKeyType.CITIZEN_CODE,
        govcrmCustomercode: '1234567',
    },
});

// Create a new case
const createResponse = await client.createCase({
    auditRecord: HttpGovCrmClient.createAuditRecordSync('2', 'MyOrg', 'PROT002'),
    govcrmCaseCreateInputRecord: {
        govcrmSectorcode: '93742',
        govcrmKepcode: '123',
        govcrmKeptype: KepType.EDYTE,
        govcrmExternalsystem: ExternalSystemType.EKEP,
        govcrmExternalticketnumber: 'INTEGRATION-TEST-CREATE',
        govcrmCasetype: '746646', // EMD code
        govcrmCasename: 'Integration Test Case Creation',
        govcrmStatus: CaseStatus.INITIAL_CREATION,
        govcrmStatusdetails: 'Integration test case creation',
        govcrmAgentcomments: 'No comments',
        govcrmCustomerkey: CustomerKeyType.AFM,
        govcrmCustomercode: '154683952',
    },
});

Helper Methods

Create Audit Record

The client integrates with the official @digigov-oss/gsis-audit-record-db package for audit record management:

// Using the official audit record package (recommended)
const auditRecord = await HttpGovCrmClient.createAuditRecord({
    auditTransactionId: 'TRANS001',
    auditUnit: 'MyOrganization',
    auditProtocol: 'PROT123',
    auditUserId: 'user1',
    auditUserIp: '192.168.1.1',
});

// Or use the synchronous helper for backward compatibility
const auditRecord = HttpGovCrmClient.createAuditRecordSync(
    'TRANS001', // Transaction ID
    'MyOrganization', // Unit name
    'PROT123', // Protocol number
    'user1', // Optional: User ID
    '192.168.1.1', // Optional: User IP
);

Date Formatting

const formattedDate = HttpGovCrmClient.formatDate(new Date()); // Returns YYYY-MM-DD
const isValid = HttpGovCrmClient.isValidDateFormat('2024-12-16'); // Returns boolean

Environment URLs

const pilotUrl = HttpGovCrmClient.getPilotUrl(); // Test environment
const prodUrl = HttpGovCrmClient.getProductionUrl(); // Production environment

Error Handling

The client provides comprehensive error handling with specific error codes:

try {
    const response = await client.updateCase(request);

    if (response.govcrmCaseUpdateOutputRecord.responseMessage) {
        // Success
        console.log('Case updated successfully');
    } else {
        // Business logic error
        console.error('Error:', response.govcrmCaseUpdateOutputRecord.message);
    }
} catch (error) {
    // Network or authentication error
    console.error('API Error:', error);
}

Authentication

The client uses Basic Authentication. Credentials are automatically encoded and included in request headers:

const client = new HttpGovCrmClient(httpReader, {
    username: 'your-username',
    password: 'your-password',
    // Other options...
});
