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
- Email delivery — Include the public link in invoice emails
- Customer portal embedding — Link from your app directly to the invoice
- Manual sharing — Copy-paste the URL to share with finance contacts
- 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.
