Use ApparelHub from ChatGPT
On ChatGPT Business or Enterprise, the fastest path is the hosted connector: add one URL, sign in to ApparelHub once, and ChatGPT gets a full set of ApparelHub tools linked to your account. ChatGPT gates connector writes to Business and Enterprise (Plus and Pro can read but not act), so this guide covers the connector first, then the Custom GPT Action and scripting paths that work on any plan.
The one-click connector (Business and Enterprise)
You need a ChatGPT Business or Enterprise workspace and an ApparelHub account.
-
Open ChatGPT settings and go to Connectors (developer mode or apps, depending on your workspace).
-
Add a custom connector and paste:
https://mcp.apparelhub.ai -
Sign in to ApparelHub and click Approve. The connector links to your account, and ChatGPT loads the ApparelHub tools.
On Plus and Pro, ChatGPT can add the connector for reading (list your stores, products, and orders) but blocks the write actions. To build and sync from those plans, use one of the paths below.
Other paths (scripting, Custom GPT Actions, Codex)
Plain ChatGPT chat can't call our API directly because the surface doesn't ship outbound HTTP access in a way that's easy to drive from one prompt. The practical path here is to use ChatGPT as a writing partner that helps you build a small Python or Node script against the Agent API, then run the script yourself. The script picks up your API key from an environment variable and the OpenAPI spec gives ChatGPT enough context to scaffold any operation you describe.
Custom GPTs can call ApparelHub directly via the Actions feature. In the GPT Builder, add an Action and paste our OpenAPI spec from apparelhub.ai/developer/api-docs (use the "Download OpenAPI" button at the top). In the Authentication section, set the auth type to API Key, header name x-api-key, and paste a key you generated at apparelhub.ai/developer/api-keys. The Custom GPT can then call any endpoint the spec describes.
Codex (the OpenAI agent product) has its own install path that mirrors our Claude Code skill closely. Detailed instructions live in our Codex setup guide.
Notes and feedback
The connector is the same standard remote connector Claude.ai and Perplexity use, so it works on ChatGPT as soon as your workspace supports custom connectors. If you've connected ApparelHub from ChatGPT and want to share what worked on your plan, open a discussion on the apparelhub-skills repo and we'll fold it in.
A faster path that probably already exists for you
If you have Claude Code installed, the full apparelhub-skills package installs in seconds:
curl -fsSL https://apparelhub.ai/install-skill.sh | bash
The Claude Code path ships packaged helpers for the trickier mechanics (transparent background generation, embroidery thread color mapping, mockup job polling) that you'd otherwise rebuild yourself in a ChatGPT script. The full walkthrough is at apparelhub.ai/agents.
