Partner
Your company — the top-level principal behind the API key.
A partner is your company: the top of the hierarchy and the owner of everything you access through the API. It is the principal the API authenticates as.
Everything else — accounts, organizations, workspaces, documents, tools — ultimately belongs to you, the partner.
The API key is the partner
You never pass a partner identifier. Instead, your API key represents the partner: authenticating with the key tells the API which partner you are, and every request is automatically confined to the accounts your company owns.
GET /v1/me is the one endpoint that speaks about the partner directly — it verifies the key and returns the partner it belongs to. (Pass X-Account-Id as well to also confirm an account is yours; see Authentication.)
Each API key is tied to a single partner. If you are issued several keys for the same partner, they behave identically.
What the partner owns
- Accounts — one per customer. The partner can have many; you select which one a request targets with the
X-Account-Idheader. See Accounts. - Through those accounts, all organizations, workspaces, documents, and tools.
The partner’s internal identity is never exposed beyond its name and createdAt, and there is no partner create/update/delete in the API — a partner (and its keys) is provisioned for you by a LumenOne superadmin. See Authentication for how to obtain and handle keys.
