Managing API Keys
How to generate, view, and regenerate your SMLLR API key for Enterprise 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 Enterprise 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.
Find the API Key section
Scroll to the API Access or Developer section.
View your key
Your API key is displayed (partially masked for security). Click Reveal to see the full key.
Regenerating Your API Key
If you believe your API key has been compromised, regenerate it immediately:
1. Go to Settings → API Access
2. Click Regenerate API Key
3. Confirm the action
4. A new key is generated instantly — the old key stops working immediately
5. Update all your systems and integrations with the new key
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 Enterprise support.
