DIY Developer Guide: Building Custom Integrations for Cetec ERP

Overview

This DIY Developer Guide for Cetec ERP walks you through how to build secure, scalable custom integrations. Cetec ERP is a cloud-native manufacturing and distribution ERP platform offering a RESTful API, ideal for connecting to CRM systems, eCommerce platforms, financial tools, and custom business applications.

Whether you’re syncing inventory, automating work orders, or integrating invoicing processes, mastering Cetec ERP integrations will streamline your operations.

Prerequisites for Cetec ERP Integrations

• Cetec ERP instance with API access enabled
• API key or access token
• Familiarity with:
  • REST APIs
  • JSON payload structure
  • Basic Authentication or API Key Authentication
• Tools: Postman, Cetec ERP API documentation, Python/Node.js SDKs, or custom-built HTTP clients

Step 1: Authentication for Cetec ERP Integrations

Cetec ERP uses API Key authentication for secure communication.

Authentication Example:

Authorization: Token your_api_key_here

Include the token in the header for each API request.

Step 2: Endpoint Discovery and Data Mapping for Cetec ERP Integrations

Common API Resources:

• Customer Records
• Sales Orders
• Work Orders
• Inventory Items
• Invoices and Payments

Process:

• Review Cetec ERP’s API documentation thoroughly.
• Map external system fields precisely to Cetec ERP fields.

Important considerations:

• Required versus optional fields
• Referential integrity between objects (e.g., Customer to Sales Order)
• Proper formatting of data (dates, amounts, IDs)

Step 3: Building Integration Flows for Cetec ERP

Integration Patterns:

• Inbound (to Cetec ERP): Use POST or PUT to create or update records.
• Outbound (from Cetec ERP): Use GET requests to fetch data.

Example: Creating a Sales Order:

POST /api/salesorder
{
  "customer_id": "CUST001",
  "order_date": "2025-05-01",
  "items": [
    {
      "part_number": "P12345",
      "quantity": 10,
      "unit_price": 20.00
    }
  ]
}

Example: Fetching Inventory Data:

GET /api/inventory?status=active

Step 4: Error Handling and Pagination for Cetec ERP Integrations

Error Handling:

• Check HTTP status codes (e.g., 200, 400, 401, 500).
• Use returned error messages for debugging.
• Implement retries with exponential backoff.

Pagination:

• Use limit and offset query parameters for large datasets.

Example:

GET /api/customer?limit=100&offset=100

Step 5: Testing and Validation for Cetec ERP Integrations

• Test all API endpoints with Postman.
• Validate data mapping, record creation, and retrieval workflows.
• Perform load testing to assess API performance under volume.

Step 6: Deployment and Security of Cetec ERP Integrations

• Deploy applications in secure containers (AWS, Azure, Docker).
• Securely manage API keys using vaults.
• Enforce HTTPS for all data transmissions.
• Implement detailed logging and error capturing mechanisms.

Step 7: Maintenance and Monitoring for Cetec ERP Integrations

• Monitor Cetec ERP API for updates or deprecations.
• Enable real-time alerting for authentication or transactional errors.
• Track system performance through health checks and monitoring tools.

Optional Enhancements for Cetec ERP Integrations

• Webhooks or polling mechanisms for real-time updates
• Middleware platforms (Zapier, Workato) for orchestration
• Admin panels for error tracking and process monitoring
• Audit logs for transaction security

Summary

Building robust Cetec ERP integrations is key to scaling manufacturing and distribution workflows. This DIY Developer Guide for Cetec ERP gives you the tools and steps to build secure, scalable, and effective custom integrations.
