How to set up automatic export via Synchron1C in 3 steps
Synkhron1S connects to 1S via standard web services — without installing processing routines or modifying the configuration.
Step 1. Write to the Telegram bot
Open @sync1cbot and write: "I want to set up data export to Diadoc." The bot will ask a few questions: - Which 1C configuration: Accounting, Trade Management, ERP, another? - Is the database local or 1C Fresh? - Which documents to send: UPD (Universal Transfer Document), invoices, bills of lading? - Is loading incoming documents from Diadoc into 1C needed?
Access to 1C is read-only — no changes will be made to your database.
Step 2. The specialist will configure the integration.
A specialist will connect to your 1C database and Diadoc, and configure the exchange rules: - Which document types to export automatically - Which organizations and counterparties to send them to - How to process incoming documents from Diadoc - Synchronization schedule (on command or upon posting a document)
Setup takes 15 minutes. If something isn't right — a specialist will adjust it for free.
Step 3. Documents are sent automatically.
After setup: - UPD (Universal Transfer Document) is sent to Diadoc when a document is processed in 1C - Document statuses are sent to Telegram: "Sent", "Signed by counterparty", "Rejected" - Incoming documents from Diadoc are loaded into 1C automatically
Result: automatic exchange without the involvement of an accountant.

What if Diadoc changed the document format?
The platform updates automatically. You don't need to do anything — the new formats will start working on their own.
