Org-level connection

Anthropic is connected once at the org level by an admin. The credential is shared across all groups that have been granted access — individual team members don't need to connect their own accounts.

Getting your API key

Go to console.anthropic.com and sign in (or create an account)

Open Settings → API Keys

Click "Create Key" and copy it

Paste it into the Anthropic API Key card in On Belay Settings

Ready to connect?

Sign in to On Belay and open the Integrations page to add Anthropic.

Permissions (scopes)

Troubleshooting

"Invalid API key" or "Unauthorized" error
Double-check that you copied the full key without any leading/trailing spaces. Some platforms show a truncated preview — make sure to copy the full token. If the key was generated with restricted scopes, verify it includes the permissions listed above.
Connected but Claude can't access data
Check that your group has been granted access to this integration in On Belay → Groups → [your group] → Integrations. Also verify the specific scopes your group is permitted to use match what your query requires.
The key expires or stops working
Some API keys have expiration policies. Generate a new key in Anthropic and update it in On Belay → Integrations → Anthropic → Update key. Consider creating a dedicated service account or machine user for On Belay so the key isn't tied to a personal account.
