--- title: "White Cap EDI Integration | Stacksync" description: "White Cap EDI: 8 listed document types, channel comparison, record mapping and validation guidance for your integration." canonical: https://www.stacksync.com/edi/white-cap last_modified: 2026-09-15 --- # *White Cap* EDI integration guide. > 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 Plan your White Cap EDI integration using 8 listed document types across 1 channel. Compare channels, map business records and test the operational handoff.

Confirm the business unit and account before copying a mapping from another channel. 2. #### Map records and assign owners Start with purchase order or sales order, buyer order-change request, purchase-order response. For each document, assign the source system, destination record, stable identifiers and person responsible for exceptions. Agree whether a change updates an existing record or creates a new event. 3. #### Test a complete exchange Run a successful exchange and the failure cases in the mapping table. Track delivery, document validation and processing in your business system separately. Agree on the White Cap production handoff and save the results of each approved test. 4. #### Check results after launch Match records between systems using buyer purchase order, order line and trading-party identifiers. Assign an owner to missing responses, duplicates and rejected records. Test recovery before enabling automatic retries. ### Go-live checklist - The required X12 documents, versions and sample files are agreed. - Sender and receiver IDs, test connections and production connections are agreed with the channel owner. - Delivery receipts, document validation and business responses have monitoring and a named owner. - Tests cover duplicates, partial processing and reconciliation with realistic business records. ### Related documents and resources - [Field mapping workbook](https://www.stacksync.com/blog/two-way-sync-field-mapping-workbook) - [Production readiness checklist](https://www.stacksync.com/blog/two-way-sync-production-readiness-checklist) - [Evaluate your integration requirements](https://www.stacksync.com/blog/integration-evaluation-worksheet) **Sources.** Directory data as of 2026-05-07.

X12 850 Purchase Order; X12 860 Purchase Order Change Request Buyer Initiated; X12 855 Purchase Order Acknowledgment; X12 810 Invoice; X12 204 Motor Carrier Load Tender; X12 990 Response To A Load Tender; X12 214 Transportation Carrier Shipment Status Message; additional documents are shown in the mapping plan. Confirm which documents, directions and versions apply to your account. ### How should I choose the White Cap EDI channel? The directory lists 1 channels for White Cap, including White Cap. Match the channel to your actual trading relationship and compare its document list before reusing a mapping. ### Which identifiers should the White Cap mapping preserve? For X12 850 Purchase Order, plan around buyer purchase order, order line and trading-party identifiers. For X12 860 Purchase Order Change Request Buyer Initiated, use original purchase order, change revision and affected line. Use the partner guide to locate these values and check their allowed formats. ### Does a successful EDI receipt mean White Cap accepted the business document? Track delivery, document validation and business processing separately. An AS2 message disposition notification (MDN) confirms transport receipt; an X12 997 or 999 reports technical validation. Use the agreed business response or reconciliation report to confirm that the order, shipment or invoice was processed. ### What should be tested before launching White Cap EDI? Map buyer item numbers to seller SKUs and explicitly convert case quantities to the agreed unit. Resend one purchase order and confirm that only one sales order is created. Also test missing responses and recovery after a destination failure. Assign an owner to each failure and obtain partner approval before launch. ## Your last integration took months.
