Key Types:
Secret Keys (Server-Side Only):
- Format:
tybrite_sk_live_*(production) ortybrite_sk_test_*(sandbox) - Full read/write access to all endpoints
- ⚠️ NEVER expose in client-side code or public repositories
- Required for: write operations, authentication, payment verification, AI recommendations
Publishable Keys (Client-Safe):
- Format:
tybrite_pk_live_*(production) ortybrite_pk_test_*(sandbox) - Read-only access (GET requests only, plus POST semantic search)
- ✅ Safe for client-side JavaScript, mobile apps, and public code
- Allowed for: browsing products, search, CMS content, pricing queries
Endpoint-Specific Requirements:
- Authentication endpoints (
/v1/auth/*): Secret key required - Payment verification (
POST /v1/payments/verify): Secret key required - AI Recommendations (
POST /v1/recommendations): Secret key required - Semantic Search (
POST /v1/search): Both key types allowed (read-only operation) - All write operations: Secret key required
- All read operations: Both key types allowed
Using a publishable key for restricted operations returns 403 Forbidden.
Headers
Customer session access_token from /v1/auth/login or /v1/auth/verify-otp. Required whenever customer_id is supplied so the gateway can prove the caller owns that customer record. Anonymous (session-only) carts may omit it.
Bring-your-own-auth assertion for stores that manage authentication in an external identity provider (Auth0, Clerk, Cognito, Firebase, NextAuth, SSO). Provide this OR x-auth-token, not both.
Format: <base64url(JSON)>.<base64url(HMAC-SHA256(JSON))> where the JSON is { "external_id": "...", "iat": <unix>, "exp": <unix> } and the HMAC is keyed on the store's signing secret. Claim lifetime capped at 300 seconds.
