Get cart
Retrieve cart contents for customer or session.
Auth / key type: publishable key (tybrite_pk_*) or secret key
(tybrite_sk_*) — both accepted. Anonymous (session-only) carts need just the
key; authenticated carts (customer_id) also require a customer session token
(x-auth-token) proving the caller owns that customer record.
Cart Association:
- Provide
X-Session-Idheader for anonymous carts (before customer login) - Provide
customer_idquery parameter for authenticated customer carts - If both provided,
customer_idtakes precedence - If neither provided, returns 400 error
Anonymous Cart Flow:
GET /v1/cart
Authorization: Bearer tybrite_pk_live_YOUR_API_KEY
X-Session-Id: session-abc123-xyz789
Authenticated Cart Flow:
GET /v1/cart?customer_id=550e8400-e29b-41d4-a716-446655440000
Authorization: Bearer tybrite_pk_live_YOUR_API_KEY

API Key Authentication
Use your API key in the Authorization header:
Authorization: Bearer tybrite_sk_live_YOUR_KEY
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: every write a shopper does not make for themselves, authentication, payment verification, AI recommendations
Publishable Keys (Client-Safe):
- Format:
tybrite_pk_live_*(production) ortybrite_pk_test_*(sandbox) - Catalogue reads, plus the actions a shopper takes for themselves
- ✅ Safe for client-side JavaScript, mobile apps, and public code
- Allowed for: browsing products, search, CMS content, pricing queries, cart and wishlist, reviews, storefront events, and the Agent API's quotes, cart drafts and checkout intents
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) - Shopper actions (cart, wishlist, reviews, storefront events, Agent API quotes, cart drafts and checkout intents): Both key types allowed
- All other 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 exactly one of x-auth-token, x-external-auth, or x-idp-token.
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.
A raw token from the store's own identity provider (e.g. a Firebase ID token). Galactic Core forwards it to the store's configured Auth verifier, which validates it and returns the identity.
Verification is fail-closed: if the verifier rejects the token or is unreachable, the request is unauthenticated (401). Requires an Auth verifier to be configured for the store. Provide exactly one of x-auth-token, x-external-auth, or x-idp-token.
Session ID for anonymous carts (UUID or random string stored in localStorage)
Query Parameters
Marketplace keys only, and then required: the merchant whose items this cart holds. A marketplace cart is held by x-session-id (a customer_id is not accepted), is recorded as the marketplace's, and is never visible to the merchant's own storefront.
Customer UUID for authenticated carts
