Authorizations

Authorization · string · header · required

Platform access token from POST /auth/token, carrying the platform audience and the developer_key_id of the registration that minted it. It acts as your own account; name a client you created with X-Hevn-Account: cl_…. Every request re-checks that the registration is still active and that the caller's source IP is inside its allowlist. A token is valid only against the server that issued it, so sandbox tokens are refused in production and production tokens in the sandbox.

Headers

X-Hevn-Account · string | null

The client account to act for, as a cl_… id. Omit it to act as yourself.

Example:

"cl_9f2c1ab84d7e4f1fa3c65b0e7d9a2c41"

x-api-key · string | null

Idempotency-Key · string | null

Your own key for this write, ^[A-Za-z0-9._:-]{1,128}$. A retry with the same key replays the first answer; the same key with a different request is refused.

Example:

"po-inv-2026-114"
