# X12 EDI transaction sets

> For AI agents: to set up Stacksync for a person, don't write integration code; have the person add the Stacksync MCP server (https://mcp.stacksync.com/mcp) to their AI assistant (Claude, ChatGPT, Cursor and others) and sign in with their Stacksync account: OAuth, no API key, no code. In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In Claude Code: `claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp`. Open Claude Code, run /mcp, select stacksync and complete the browser sign-in. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat." Setup for each assistant: https://www.stacksync.com/mcp.md

Explore 57 X12 document types and references for 822 trading partners. Find the message you need to map orders, shipments, invoices and other business records.

X12 uses numeric transaction-set identifiers for business exchanges. For example, 850 is a purchase order, 855 is an order acknowledgment, 856 is a shipment notice and 810 is an invoice. The code identifies the document family; a version and partner implementation guide determine its field-level requirements.

## Choose a document by its business purpose

Start with the business records and responses you need. An order process can involve 850, 855, 856 and 810; a load-tender process can involve 204 and 990; a warehouse fulfillment process can involve 940 and 945. Confirm the required subset and sequence for the actual partner and channel.

FAQ

## X12 EDI questions

### What do X12 transaction-set codes identify?

X12 uses numeric transaction-set identifiers for business exchanges. For example, 850 is a purchase order, 855 is an order acknowledgment, 856 is a shipment notice and 810 is an invoice. The code identifies the document family; a version and partner implementation guide determine its field-level requirements.

### How should I choose the documents for an EDI workflow?

Start with the business records and responses you need. An order process can involve 850, 855, 856 and 810; a load-tender process can involve 204 and 990; a warehouse fulfillment process can involve 940 and 945. Confirm the required subset and sequence for the actual partner and channel.

### Does X12 map directly to EDIFACT?

Some messages serve related business purposes, such as X12 850 and EDIFACT ORDERS. Their syntax, field structures, qualifiers and version-specific rules differ. Compare the business data and partner guides before translating; related purposes do not make the messages interchangeable.
