#Can't add chat GPT oauth
1 messages · Page 1 of 1 (latest)
ChatGPT Plus (the web app subscription) and the OpenAI API are billed separately.
So if OpenClaw is using an openai/... model (regular OpenAI API), you still need an API key with API billing enabled on the OpenAI Platform account. That error usually means the API account has no credits / no payment method / exhausted quota.
You have two valid paths:
- Use the OpenAI API (needs API key + billing)
- Add billing / payment method on the OpenAI Platform, then create an API key.
- Configure
OPENAI_API_KEY(or paste it in the wizard).
Docs: https://docs.openclaw.ai/concepts/model-providers (OpenAI section)
- Use “subscription OAuth” (no API key) via Codex
OpenClaw supports ChatGPT sign-in for theopenai-codexprovider (Codex), not the normalopenaiAPI provider:
openclaw models auth login --provider openai-codex
openclaw models set openai-codex/gpt-5.2
