auth

Exchange an API key for a short-lived POS terminal JWT

Exchange a long-lived x-api-key (presented in the x-api-key header) for a short-lived POS terminal JWT (HS256, 600-second TTL) that the terminal uses on cashier-scoped money and identity calls. The JWT carries scope claims derived from the key (integration_id, enterprise_id, brand_id, branch_id), an optional server-validated cashier_id (max 64 chars, no control characters, validated rather than trusted from the body alone), and a sandbox claim mirroring the key. The terminal JWT is domain-separated from the consumer JWT (distinct issuer/audience and a versioned signing context), with iss=feddi-pos-terminal and aud=feddi-api, so a consumer JWT can never be mistaken for a POS terminal JWT and vice versa. A revoked or expired key, or a key whose integration is not ACTIVE, returns INVALID_API_KEY (401). This is an authentication exchange, not a money or identity-resolution call: it returns a JWT, never a debit token and never customer PII. Idempotent on the Idempotency-Key header: a retried exchange within the validity window replays the same JWT.

Authorizations

x-api-key

string

header

required

Partner API key (platform- or merchant-scoped). Contract key-enforces context.merchant_id.

Headers

Idempotency-Key

string<uuid>

required

Partner-generated UUID; the ONE dedup key for all mutating endpoints. 24h TTL. Same key + same payload -> byte-identical replay; same key + different payload -> IDEMPOTENCY_KEY_REUSED (422).

Body

application/json

Exchange the x-api-key (header) for a short-lived POS terminal JWT. The raw key is in the x-api-key header, NOT the body.

Response

JWT minted. Domain-separated POS terminal token with scope claims.

The standard response envelope that every enveloped endpoint serializes through. ok is a boolean discriminator: when ok is true, the typed result is carried in data; when ok is false, a typed error object is returned instead. The meta object is uniform across the entire API surface.
