API Integration Guide for Systech ERP

Systech APIs follow REST architectural style using standard HTTP methods (GET, POST, PUT, DELETE), stateless communication, resource-based URLs, and JSON payloads.

API version is specified in URL path (e.g., /api/v1/). Older versions remain supported for backward compatibility. New integrations should use latest version.

API requests are rate limited to protect system performance. Default limits are 1000 requests per hour per API key. Contact support for higher limits if needed.

All API requests and responses use JSON format with UTF-8 encoding. Date fields use ISO 8601 format. Numeric fields are transmitted as numbers, not strings.

Obtain API key from system administrator. Include API key in request header: Authorization: Bearer YOUR_API_KEY. Keep API keys secure and rotate periodically.

For user-context integrations, OAuth 2.0 is supported. Implement standard OAuth flow to obtain access tokens. Tokens expire after 1 hour and must be refreshed.

Optionally restrict API access to specific IP addresses or ranges. Configure whitelisting in system administration module.

All API endpoints require HTTPS. HTTP requests are automatically redirected to HTTPS. Use TLS 1.2 or higher.

Sync products, inventory, prices, and orders between ERP and e-commerce platform. Real-time inventory updates prevent overselling. Orders created in e-commerce automatically generate sales orders in ERP.

Import bank statements automatically for reconciliation. APIs support multiple bank formats including MT940, BAI, and CSV. System matches transactions to payments and highlights exceptions.

Generate shipping labels, track shipments, and update delivery status. Integration with major carriers including Blue Dart, DTDC, Delhivery, and others.

Process online payments and update ERP automatically. Support for Razorpay, PayU, CCAvenue, and other Indian payment gateways.

Automatically import test results from USTER HVI, AFIS, Tensorapid, and Classimat. Test results linked to production lots through QR codes.

System monitors incoming test data and generates alerts when parameters exceed limits. Email and SMS notifications to quality team.

Historical test data enables trend analysis and SPC charting. Identify quality drift before parameters go out of spec.

USTER integration requires network connectivity between USTER PC and ERP server. Configuration wizard simplifies setup and testing.

GET /api/v1/customers - List customers GET /api/v1/customers/{id} - Get customer details POST /api/v1/customers - Create customer PUT /api/v1/customers/{id} - Update customer DELETE /api/v1/customers/{id} - Delete customer

GET /api/v1/items - List items GET /api/v1/items/{id}/stock - Get stock levels POST /api/v1/stock/adjustment - Adjust stock GET /api/v1/warehouses - List warehouses

POST /api/v1/sales-orders - Create sales order GET /api/v1/sales-orders/{id} - Get order details PUT /api/v1/sales-orders/{id}/status - Update order status GET /api/v1/invoices - List invoices

POST /api/v1/work-orders - Create work order GET /api/v1/work-orders/{id} - Get work order POST /api/v1/production/report - Report production GET /api/v1/quality/tests - List quality tests

const response = await fetch("https://api.systecherp.com/v1/customers", { method: "GET", headers: { "Authorization": "Bearer YOUR_API_KEY", "Content-Type": "application/json" } }); const customers = await response.json();

import requests headers = { "Authorization": "Bearer YOUR_API_KEY", "Content-Type": "application/json" } response = requests.get( "https://api.systecherp.com/v1/customers", headers=headers ) customers = response.json()

using (var client = new HttpClient()) { client.DefaultRequestHeaders.Add( "Authorization", "Bearer YOUR_API_KEY"); var response = await client.GetAsync( "https://api.systecherp.com/v1/customers"); var customers = await response.Content .ReadAsStringAsync(); }

Always check HTTP status codes. Implement retry logic for transient failures. Log errors with sufficient context for troubleshooting. Handle rate limiting gracefully.

Validate data before sending to API. Check required fields, data types, and business rules. API will reject invalid requests with descriptive error messages.

Use bulk APIs when processing multiple records. Implement pagination for large result sets. Cache reference data that changes infrequently. Minimize API calls through efficient design.

Log all API requests and responses. Monitor integration health and set up alerts for failures. Track API performance and optimize slow operations.
