Accessing a Public Invoice

The public invoice endpoint requires no authentication:
Returns the full invoice with:
  • Customer details
  • Organization branding (logo, colors)
  • All line items
  • Tax breakdown
  • Total due
  • Bank account details (if configured)
  • Payment link (if a gateway is configured)

​
Security

  • Public tokens are cryptographically random UUIDs
  • Tokens can be regenerated (invalidating old links) by calling generate-token again
  • Public pages don’t expose any other customer or organization data

​
Use Cases

  1. Email delivery — Include the public link in invoice emails
  2. Customer portal embedding — Link from your app directly to the invoice
  3. Manual sharing — Copy-paste the URL to share with finance contacts
  4. Payment collection — The public page includes a payment button when a gateway is connected
Regenerate the public token if a link is accidentally shared with the wrong person. The old link immediately becomes invalid.
