Bearer tokens

All API requests must include a Bearer token in the Authorization header:
Requests without a valid token return a 401 Unauthorized error. To check a key without touching any resources, call GET /v1/me — it requires no scope and returns the workspace name, plan, scopes and environment behind the key:

​
API key format

QRKit API keys use a prefix to indicate the environment:
Test keys work identically to live keys and create real QR codes in your workspace (marked internally as created by a test key), so you can verify the full flow end to end. Delete test codes when you’re done — they appear in your dashboard like any other code.

​
Scopes

Each API key has one or more scopes that control what it can access:
Follow the principle of least privilege. Only grant scopes that your integration needs.

​
Creating API keys

API keys are created from the QRKit dashboard (recommended) or via the Tokens API. API access requires a paid plan. When you create a key, the full key value is returned once. Store it securely — you won’t be able to see it again. The dashboard and API only show the key prefix (e.g., qr_live_a1b2) for identification.

​
Key rotation

Rotate API keys using the Rotate endpoint or the dashboard. This creates a new key with the same name, scopes and expiry, and revokes the old one.
Token management endpoints (/tokens/*) are authenticated with your QRKit dashboard session (a Clerk session JWT), not with an API key — a leaked API key can never mint new keys.

​
Key expiration

API keys can optionally have an expiration date. Set expires_in_days when creating a key:
Expired keys return a 401 Unauthorized error. Create a new key or use rotation before the current key expires.

Security best practices

1

Use environment variables

Never hardcode API keys in source code. Use environment variables or a secrets manager.
2

Use test keys for development

Use qr_test_ keys during development and CI/CD. Switch to qr_live_ only in production.
3

Rotate regularly

Set up a rotation schedule for your production keys (e.g., every 90 days).
4

Minimize scopes

Grant only the scopes your integration needs. A read-only dashboard only needs qr:read.
