Using the QR code API

For: DevelopersDifficulty: Advanced⏱ 5 min

Step by step

1. On QR codes, choose More → API to open Developer tools · QR API. Workspace owners and admins can manage keys.
2. Choose Create key, name it, and pick its scopes: codes:read, codes:write, analytics:read, bulk:write.
3. Copy the key now — it starts lvqr_ and is shown only once. LinkVault keeps a secure hash, not the key.
4. Send it with every request as Authorization: Bearer lvqr_… to https://accounts.linkvault.bio/api/qr/v1.
5. The full reference — listing, creating and changing codes, pointing a printed code somewhere new, pause and resume, the SVG image, analytics and bulk — is on the same page, and always matches the API that is running.

Tips

• Limits: 60 requests a minute per key and 10,000 a month per workspace. Requests the API refuses (a bad key, a missing scope, a rate limit) do not count towards the month.
• Errors always come back in one shape: {"error": {"code", "message", "fields"}}.
• Recent API calls shows what each key did. Request bodies are never stored — they can contain passwords and phone numbers.
• A key belongs to the workspace, not to the person who made it, and acts with the workspace’s current plan. Revoke stops it immediately.
• The QR code API is included on Premium and Enterprise.
