# Trust boundaries you can actually inspect.

SeatLayer minimizes the data it holds, keeps credentials on the correct side of the browser, isolates every organizer workspace, and makes retries safe by construction.

- BUYER
- ORGANIZER
- BACKEND
- WEBHOOK
## The browser can request. Only trusted systems commit.

Each surface receives the narrowest useful credential, and every commercial decision is re-established on the server.

### Public event access, not account authority

Rendering and holds use the event key. sk_live_ and sk_test_ remain on your backend for provisioning, hold inspection and booking.

### One serialization point per event

Every hold, booking and release is ordered through one stateful event authority, preventing a double-sale race window by construction.

### Inspect the hold before payment

Your backend receives event, mode, workspace, expiry and immutable line items. Browser-supplied prices, tiers and labels are never payment authority.

### Buyer identity stays out of seat inventory

Headless inventory routes need no buyer identity. When hosted checkout is used, the order service stores the contact details needed to issue tickets; complete card details stay with the payment provider.

## One organizer cannot become another organizer.

Charts, events, embedded sessions and webhook routing remain bound to an immutable workspace boundary.

### Immutable resource ownership

Platforms assign every organizer’s charts and events to one workspace. Events inherit ownership from the published chart.

### Origin-, chart- and workspace-scoped

Short-lived tokens are stored hashed, can be revoked immediately, and expose explicit publish permission. Browser messages validate source and origin.

### Passwordless authentication

Dashboard access uses a one-time email code. SeatLayer stores no reusable user password or password hash.

### TLS across every surface

API, dashboard, documentation, CDN and WebSocket traffic use HTTPS or WSS. There is no plaintext application mode.

## Retries remain transport events—not duplicate business events.

Signatures establish authenticity; stable identifiers and idempotency establish safe processing behavior.

### HMAC-SHA256 signed payloads

Receivers verify the raw request body against the endpoint secret before trusting the occurrence.

### Stable occurrence identifiers

Process an occurrence once even when delivery is retried. Delivery attempts remain separately inspectable.

### Idempotent provisioning and booking

Stable request keys and booking references make network retries safe without duplicating organizers, events or sales.

### Hashed, rotatable and revocable

Account secrets are shown once, stored hashed, mode-scoped, and can be rotated or revoked without redesigning the integration.

## Review what is published today.

SeatLayer does not ask you to infer reliability from a badge. Inspect the live service, implementation guidance and change history directly.

### Status and incident visibility

Inspect the public service state with a live browser probe before integrating.

### API and security behavior

Review authentication, errors, webhooks, test mode and integration boundaries.

### Published product changes

Follow changes to the SDK, API and operational surfaces over time.

### Ask the architecture questions

Request additional implementation detail for an enterprise evaluation.

### getseatlayer.com · seatlayer.dev · seatlayer.events

getseatlayer.com is an outreach sender domain and redirects to seatlayer.io. seatlayer.dev is an outreach sender domain and redirects to seatlayer.io/developers/. seatlayer.events is the customer storefront namespace. Account sign-in remains on app.seatlayer.io.

## Found a vulnerability?

Tell us directly with enough detail to reproduce it, and give us a reasonable window to investigate and fix it before public disclosure.
