Creates and finalizes a one-off invoice and answers with url, the Stripe page where your customer pays it (card). Nothing is sent: share url, or POST /api/v1/invoices/{id}/send to email it from your business name. Amounts are integer cents. Give amount, or line_items (then amount may be left out, or must equal their total). customer needs an email or a phone. due_date is a date (2026-11-01, due at the end of that day UTC) or unix seconds, within 365 days; without one the invoice is due 30 days after it is made. Every create needs an Idempotency-Key header (a UUID, new for each invoice): a retry with the same key within 24 hours answers with the same invoice instead of making a second one.

Money: a destination charge to your Stripe Connect account, made on its behalf, so the invoice, the payment page and the card statement carry your business name. Orgo keeps only what Stripe charges it for the invoice, the card fee (2.9% + 30¢) and the Invoicing fee (0.5%), as orgo_fee; payout is paid out to you. Needs Invoicing (every paid plan) and payouts set up in Settings → Invoicing. Use an account-wide API key.
