Fix Minimax Portal OAuth 401 Error
[minimax-portal] OAuth 401 Unauthorized
Error: minimax-portal authentication failed
Token exchange response: {"error": "invalid_token"}This issue was introduced in OpenClaw 2026.2.26. If you updated from an earlier version and are using minimax-portal, you need to regenerate your API key.
OpenClaw 2026.2.26 updated the Minimax Portal OAuth integration. Tokens generated under the old format are rejected with a 401 Unauthorized error. The fix is to regenerate your Minimax Portal API key and update your OpenClaw credentials.

Step 1: Regenerate Your Minimax Portal API Key
Go to minimax.io and log into your account.
Navigate to Dashboard → API Keys (or Settings → API).
Find your existing API key and click "Revoke" or "Delete".
Click "Create New API Key" and save the new key securely — it will only be shown once.
Step 2: Update Credentials in openclaw.json
{
"credentials": {
"minimax-portal": {
"apiKey": "YOUR_NEW_MINIMAX_API_KEY",
"groupId": "YOUR_GROUP_ID"
}
}
}After updating the config, restart the gateway to apply the new credentials:
openclaw gateway restart
Alternative: Use Direct Minimax API Instead of Portal
If you continue to have Portal OAuth issues, you can switch to the direct Minimax API which uses a simpler API key in the Authorization header:
{
"model": "minimax/MiniMax-Text-01",
"credentials": {
"minimax": {
"apiKey": "YOUR_MINIMAX_API_KEY"
}
}
}The direct Minimax API and minimax-portal may have different model names and endpoints. Check the Minimax API docs to confirm which models are available on each provider.
Verify Authentication
# Check gateway logs after restart openclaw gateway logs | grep -i minimax # Run diagnostics npx clawkit-doctor@latest
You should see [minimax-portal] Authenticated successfully in the gateway logs (or no auth errors). Try sending a test message to confirm end-to-end functionality.
