Using the API and managing API keys
If you want to send documents programmatically instead of through the Inkless interface, generate an API key from Settings → API Keys.
Available on Starter (50 document sends/month) and Starter Team (250 document sends/month) plans.
Creating a key
- Go to Settings → API Keys and click Create Key.
- Optionally add a description (e.g., "Production server") and an expiration date — leave the expiration blank for a key that never expires.
- Click Create Key.
- Copy your key immediately. For security, Inkless shows it to you exactly once — there's no way to view it again later, and you can't dismiss this screen with Escape or by clicking outside; you have to click Done.
Authenticate your API requests by sending the key in an x-api-key header.
Viewing usage
The API Usage card shows how many document sends you've used this month against your plan's limit, and when the count resets.
Managing existing keys
The keys table shows each key's prefix (not the full key — that's never shown again after creation), description, creation date, expiration, last-used date, and status: Active, Expired, or Revoked.
To retire a key, click Revoke. This takes effect immediately and can't be undone.
Note: There's currently no way to regenerate or rotate a key in place — if you need a replacement, revoke the old one and create a new key.
