What Attio (BYOK) is for

Attio (BYOK) lets an AI assistant read your own Attio data through the Attio API with a key you supply (Attio API key (access token)). Read-only: 10 tools (get_token_info, list_objects, query_records, get_record, search_records, list_lists, query_list_entries, list_workspace_members, list_notes, list_tasks). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.attio.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Attio. Attio and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "Which Attio workspace is my API key for, and what can it access?"
  • "What objects exist in my Attio workspace?"
  • "List my Attio companies"
  • "Show Attio person record 891dcbfc-9141-415d-9b2a-2238a6cc012d"
  • "Find the Attio company Acme"
  • "What lists do I have in Attio?"

What it does

  • get_token_info: Show the workspace the Attio key belongs to (name, slug, id) and the scopes and level of the token.
  • list_objects: List the objects of the workspace (people, companies, deals and custom ones) with their slugs and names.
  • query_records: List records of one Attio object (for example people or companies) in the default order. Each record carries its attribute values.
  • get_record: Get one Attio record by object and record id, with all its attribute values.
  • search_records: Search Attio records of one object by text (names, emails, domains) and get a label per hit. Searches as the whole workspace.
  • list_lists: List the Attio lists (pipelines and other curated record collections) with slug, name and parent object.
  • query_list_entries: List the entries of one Attio list (for example a sales pipeline) with the parent record and the entry's own attribute values.
  • list_workspace_members: List the members of the Attio workspace with name, email and access level.
  • list_notes: List Attio notes, optionally for one record (give both parent_object and parent_record_id). Returns title and plain text.
  • list_tasks: List Attio tasks with deadline, completion state, assignees and linked records. Can filter to open or completed tasks.

BYOK key

You bring your own Attio Attio API key (access token) (https://docs.attio.com/rest-api/guides/authentication). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.attio.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Attio API (api.attio.com) with a BYOK key; documentation: https://docs.attio.com/rest-api/overview. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Attio.
