Email each automatic invoice to the payer

30 October 2026 — Each connected Stripe account can now email every invoice that Factuarea issues automatically to the person who paid, using the address that comes with the Stripe charge. Read the Stripe auto-invoicing guide for the whole flow.

• New option — email_invoice_to_payer is a boolean, false by default. When it is true, each invoice issued and paid from a charge, a Checkout, a Stripe invoice or a subscription cycle is emailed with your company template and its PDF, without a payment button.
• The address is not stored — the email of the charge is only where the invoice is delivered. A simplified invoice keeps no recipient, and an invoice issued to an identified customer keeps that customer.
• How to set it — on the update operation, omitting email_invoice_to_payer leaves it as it is. A value that is not a boolean returns 422 parameter_invalid_value with param email_invoice_to_payer.
• Where it is returned — connected accounts return email_invoice_to_payer in every response that describes them.
• Traceability — the outcome of each email is an integration event: autoinvoice.email_requested, autoinvoice.email_skipped when the charge has no valid email, or autoinvoice.email_failed when the email is rejected. The invoice and the payment are kept in every case.
• MCP tool — update_stripe_connected_account accepts email_invoice_to_payer.

Integrations that do not send the field need no changes: no invoice is emailed until the option is turned on.
