Use ApparelHub from ChatGPT
ChatGPT can drive ApparelHub but the path depends on which ChatGPT surface you use. This page covers what's possible today and what we're still validating.
Three different surfaces, three different setups
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.
What we're still validating
We're working through each of these paths end-to-end and will publish full step-by-step walkthroughs with screenshots, error messages you might see, and verification steps. The Custom GPT path is the closest to ready; the script path involves your own runtime so the variations are larger.
If you've gotten ApparelHub working from ChatGPT and want to share what worked, open a discussion on the apparelhub-skills repo. We'll fold what you share into the published guide and credit you.
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.
