Quickstart
Make your first request in about a minute, with a key you already have.
Create a key in Settings → API keys, then make a request. There is no OAuth dance to work through first — that is only needed when your app acts on other people’s accounts.
curl https://app.360nook.com/api/v1/contacts \ -H "Authorization: Bearer nook_sk_your_key"
What can this key do?
Ask it. GET /v1/me returns the workspace, the scopes, and whether the key may pass sub_account_id — the three things people usually discover by getting a 403.
curl https://app.360nook.com/api/v1/me \ -H "Authorization: Bearer $KEY"
Every response carries X-Request-Id. Quote it to us and we can find the exact request rather than asking you to reproduce it.
