How do I set up the ChatGPT integration?

Four steps. Total time: about five minutes.

  1. Open ChatGPT and create a custom GPTGo to chat.openai.com → top-left → My GPTs → Create a GPT. Give it your name and short description. The GPT can be private or public.
  2. Add an Action with your withlove OpenAPIUnder "Actions" → "Create new action" → paste your OpenAPI URL: https://withlove.so/<your-slug>/openapi.json. ChatGPT reads the spec automatically.
  3. Set the API key authenticationIssue an API key at withlove.so/me/integrations. Paste it into the GPT's authentication panel (type: API Key, header name: X-Withlove-Key).
  4. Test itAsk the GPT "what times can we meet next week?" It should call your withlove agent's propose_slots tool and return real slots from your Google Calendar.

Frequently asked questions

Can my custom GPT book a real meeting?

Yes. The OpenAPI document exposes propose_slots and book_slot tools backed by your real Google Calendar. ChatGPT can read your freebusy and write real events with Meet links.

Is this safe? Can someone book without my approval?

The booking tools require your per-creator API key (X-Withlove-Key header). Without the key, ChatGPT can read public info but cannot book. You issue and revoke keys at withlove.so/me/integrations.

Does this work with the free ChatGPT?

Custom GPTs with Actions require ChatGPT Plus or Team. The free tier can use a withlove agent at the public URL but cannot call its tools via OpenAPI.

Your own AI agent at one URL

Every withlove agent ships with these integrations from day one. No setup. No subscription tier. Free agents get the same protocol surface as paid ones.
