Managing API Keys
How to generate, view, and regenerate your SMLLR API key for Premium plan integrations.
What is an API Key?
An API key is a secret credential that allows your software systems to interact with SMLLR programmatically — without a human logging in. With an API key, your systems can:
- Retrieve analytics data
- List QR codes and campaigns
- Pull performance reports for specific clients
API access is available on the Premium plan.
Where to Find Your API Key
Your API key is a secret. Do not share it publicly, commit it to code repositories, or include it in client-side JavaScript. Treat it like a password.
Go to Settings
Click Settings in the left sidebar.
Click the API tab
At the top of the Settings page, click the API tab.
Generate or view your key
If no key exists, click Generate Secure API Key. Your key is shown once — copy it immediately. On return visits, the key is masked; use Reveal to view it.
Regenerating or Revoking Your API Key
If you believe your API key has been compromised, regenerate it immediately:
1. Go to Settings → API tab
2. Click Regenerate Key to issue a new one, or Revoke Key to permanently delete it
3. The old key stops working instantly
4. Update all your systems with the new key before losing the page — it will not be shown again
Regenerating your API key immediately invalidates the old key. Any systems using the old key will stop working until you update them with the new key.
API Rate Limits
The SMLLR API allows up to 60 requests per minute per API key. Requests above this limit receive a 429 (Too Many Requests) response.
For higher rate limits, contact SMLLR support.
