# Register business

> Create a new Tyms business using a **partner** API key.

<Warning>Call with your **partner** API key in `X-API-Key`. Do not use a business `tyms_sk_` key. After success, use the returned **`api_secret_key`** for all other endpoints.</Warning>

  title: Adam Developer API
  version: 1.0.0
  description: >-
    REST API for useadam.io — Adam, the AI accounting agent for small
    businesses. Paths are appended to the server URL.


    **Business key** (`tyms_sk_...`): all routes except `POST
    /register-business` and OAuth authorization steps that document their own
    auth. **Partner key** (`adam_partner_sk_...` or equivalent): only `POST
    /register-business`. **OAuth**: integration apps use `tyms_pk_...` /
    `tyms_sk_...` plus user Bearer tokens — see the OAuth guide.


    Financial reports match what you see in the Adam app. AI create endpoints
    accept optional attachment objects (`name`, `file`, `type`) — see the
    Attachments page in this docs site.
