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."

A customer order looks ready in the CRM while resin approval, mold availability or a color change still blocks the run.

Pick the customer service lead who fields the is-it-ready question, and pair them with the planner who owns the Molding order. Between them they can name the approved material, tool and quantity for one program, and they know when a Resin lot is still on hold. Loop in the NetSuite or Salesforce administrator before enabling changes. Quality keeps the release decision on the Resin lot; two-way sync makes that state visible without granting it. ### When is a resin substitution or a color hold ready for a Stacksync workflow? It is ready when you can point to the Molding order it affects and name who approves the change. For a substitution, purchasing supplies the candidate material and availability, and engineering and quality decide suitability against the customer’s requirements. For a color hold, quality defines the held quantity and planning decides what still ships. The workflow collects the evidence and routes each decision; a substitute stays a proposal, not an approved material, until that decision is recorded. ### What should a plastics manufacturer ask to see in a NetSuite and Shopify demo? Ask to follow one Customer item cross-reference through a pack-based Shopify order, a finished-goods color lot placed on hold after the order was accepted, and a repeated order message. You should see the store quantity kept in its original unit, the held lot removed from the saleable count, and no duplicate order after the replay. Shopify and NetSuite writes are scoped to specific objects, so ask which order and inventory operations are in scope before you sign off.
