API (official)

• Base URL: https://api.attio.com

• Auth: send the header Authorization: Bearer $ATTIO_API_KEY
• Get a key: https://attio.com/help/reference/apps/generating-an-api-key

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
