agency-invoicing
POST /v1/agency-invoicing/invoices/{invoiceId}/send
Email the invoice to your client, with the PDF attached.
Authentication
Send an API key as a bearer token. The key must carry the agency.invoicing.manage permission; a key without it is refused with 403, not 404.
Where your organisation id goes
This endpoint takes org_id as a query parameter. Leave it out and the call covers your whole tenancy subtree; send it to narrow the call to one organisation.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

Details
Issues it first if it is still a draft. Leaves on YOUR mail account when you have connected one, otherwise on ours with your address as Reply-To and a line saying who issued it. The PDF is attached as bytes rather than linked — a link would expire, and it would put our storage hostname in front of your client. Requires agency.invoicing.manage.
