50 USD🧩 Project: 1C Middleware Integration (Node.js + Bitrix24 + Didox)
Goal:
Connect an existing Node.js middleware (already built and working) to the correct 1C endpoints, and ensure smooth integration between 1C, Bitrix24, and Didox platforms.
📋 Project Overview
We are building an automated accounting system that connects:
Telegram Bot → for clients
Middleware (Node.js) → central connector
Bitrix24 CRM → client & invoice management
1C:Enterprise 8.3 (Server) → accounting and invoice creation
Didox API → electronic invoice signing and submission
E-IMZO → electronic signature
Bank API → payments integration
The middleware and documentation are already prepared.
Your task is to connect and configure the 1C integration endpoints correctly and ensure end-to-end data flow.
🧠 Your Tasks
Review existing documentation (includes middleware endpoints, payloads, and 1C script examples).
Connect 1C REST endpoints to the middleware:
/createInvoice/getInvoiceStatus/sendInvoice
Ensure proper XML/JSON structure between 1C ↔ Didox ↔ Middleware.
Integrate Bitrix24 with 1C through middleware using REST API or Webhooks.
Test full data flow:
Telegram → Middleware → 1C → Didox → Bitrix24 → Back to Telegram.Provide a short integration report (what was done, how to test it).
⚙️ Tech Stack
1C:Enterprise 8.3.25+
Node.js (Express)

Bitrix24 Cloud API
Didox API (REST)

📦 What’s Ready
✅ Full Node.js middleware (with endpoints, database schema, and queue system).
✅ Postman collection for testing.
✅ 1C HTTP examples (HTTPЗапрос) and sample XML payloads.
✅ Didox sandbox access.
✅ Google Sheet + Apps Script PoC CRM.

I have experience integrating 1C with external systems via REST API and HTTP requests, including setting up the correct XML/JSON structures for data exchange. My team specializes in building reliable middleware integrations, testing data flows, and documenting the process for future use.
I can connect 1C endpoints to your Node.js middleware, ensure integration with Bitrix24 and Didox, test the complete data flow from Telegram to 1C and back, as well as prepare a brief report on the integration and instructions for testing.
I am ready to start work after discussing the details and budget of the project.
