Email an invoice to the customer

POST/api/v1/invoices/{id}/send

Sends the customer a link to the online invoice and a PDF copy. A draft is issued first, with the same rules as issueInvoice (422 invoice_has_no_items when it has no lines), taking issue_date and due_date when given. A void invoice returns 409. Emails are limited to 100 a day per account.

Needs an API key, and runs with the access of the member who made the key.
Send an Idempotency-Key. The same key with the same request within 24 hours gives the first answer again and changes nothing.
A connected AI assistant can use it too, as sendInvoice.

Fields(49)
- lock_versionintegerrequired
  At least 0.
- created_atstring (date-time)required
- updated_atstring (date-time)required
- idstring (uuid)required
- account_idstring (uuid)required
- customer_idstring (uuid)required
- job_idstring (uuid) or null
- quote_idstring (uuid) or null
- kindstring
  `deposit` for the invoice issued when a quote that asks for a deposit is accepted; its `quote_id` is that quote. It is an invoice like any other: sent, paid, reminded about and voided the same way. Every other invoice is `standard`. Read-only.
  One of: standard, deposit.
- deposit_invoice_idstring (uuid) or null
  The deposit invoice this invoice takes off. The first invoice for a job whose quote had its deposit invoiced deducts it, once: the one invoice of a job billed on completion always, and for a job billed by visit the first invoice that comes to at least the deposit. An invoice made with createInvoice that names the job counts as the job's. A deposit invoice that has been voided is never deducted, and voiding or deleting the invoice that deducted one leaves it to be deducted again. Read-only.
- deposit_deduction_centsinteger (int64)
  The deposit invoice's amount before tax, taken off this invoice before tax beside `discount_cents`: `total_cents` is `subtotal_cents` less `discount_cents` less this, plus `tax_cents`. `tax_cents` is then the tax the lines carry after the discount, less the tax the deposit invoice charged, so the two invoices come to exactly what one would have. When the lines come to less than the deposit, all of them comes off and nothing is left to pay. 0 when no deposit is taken off. Read-only.
  At least 0.
- numberstringrequired
- titlestringrequired
- descriptionstring or null
- statusstringrequired
  One of: draft, issued, void.
- payment_statusstringrequired
  `written_off` when the business has written off what was left to pay (writeOffInvoice): settled, and never received.
  One of: unpaid, partially_paid, paid, written_off.
- overduebooleanrequired
  Past its due date with something left to pay. Never while `collecting`, or while `collect_on` is set.
- collectingbooleanrequired
  A payment is on its way and has not cleared: one the customer made online, or a Direct Debit. The invoice is not overdue, cannot be voided and is not to be chased.
- collecting_centsinteger (int64)required
  How much is on its way: the invoice's `pending` payments.
  At least 0.
- collect_onstring (date) or null
  The day the customer's bank is expected to be debited, when the invoice is going to be collected by Direct Debit without anybody asking: the due date, or the next working day; later when the invoice was issued with less than two working days to go, and on a bank holiday. Null for any other invoice, and once a collection has been started. An invoice collects itself only if it was issued while its customer's Direct Debit was in force, and nothing has been paid or tried online for it: one issued while a new Direct Debit was still being confirmed by the customer's bank is paid some other way, or collected with collectInvoice.
- collectablebooleanrequired
  Whether collectInvoice would start a Direct Debit for what is left to pay now.
- direct_debit_failedbooleanrequired
  True when the last Direct Debit collection tried for the invoice failed, or could not be started, and something is still left to pay. Nothing is tried again by itself: it stays true until collectInvoice starts another collection or the invoice is paid some other way. A payment recorded by hand with the method `direct_debit` does not count as a collection.

  Payments that have `succeeded`, less what was refunded.
  At least 0.
- written_off_centsinteger (int64)required
  What the business wrote off with writeOffInvoice because the customer will not pay it: settled, and never received, so it is not in `paid_cents`. 0 unless written off.
  At least 0.
- written_off_atstring (date-time) or null
  When it was written off. Null unless it is.
- write_off_reasonstring or null
  Why it was written off. The customer is never shown it.
  Up to 255 characters.
- written_off_by_membership_idstring (uuid) or null
  The member who wrote it off.
- balance_due_centsinteger (int64)required
  What is left to pay: the total less `paid_cents` and `written_off_cents`, and never below zero.
  At least 0.
- issue_datestring (date) or null
- due_datestring (date) or null
- issued_atstring (date-time) or null
- paid_atstring (date-time) or null

  When the invoice was last emailed.
- sent_to_emailstring (email) or null

  At least 2 characters. Up to 2 characters.
  propertystring or null
  The property the work was at, on one line, printed as "Property: …".
- invoice_remindersstringrequired
  Whether the overdue reminders the workspace sends by itself go for this invoice: `default` follows its customer's `invoice_reminders`. The one field an issued invoice can still change: send it with `lock_version` alone.
  One of: default, on, off. Default: "default".
- remindersobject or nullrequired
  Where the invoice's overdue reminders stand. Null for an invoice that asks for nothing: a draft, a void or archived invoice, and one with nothing left to pay.
  Read only.
  Fields(5)
  settingstringrequired
  Whether an email the workspace sends by itself goes: `default` follows the workspace's switch, `on` sends it even while that is off, and `off` never does. The most specific setting wins: an invoice's own over its customer's, and a customer's over the workspace's. Set to `on`, it counts from that moment, so nothing already overdue or awaiting an answer is chased that day. Emails a person sends are not affected.
  One of: default, on, off. Default: "default".
  sentintegerrequired
  How many reminders the customer has been sent about it, by themselves or with sendInvoiceReminder.
  At least 0.

  The most that are sent by themselves, the workspace's `invoice_reminder_limit`.
  At least 1.
  next_onstring (date) or nullrequired
  The first day the next reminder can go by itself, in the workspace's time zone. A refund, a failed payment or a dispute can hold it back. Null when `reason` says why none will.
  reasonstring or nullrequired
  Why no reminder will go by itself. `collecting`: a payment is on its way. `direct_debit`: a Direct Debit is going to collect it. `customer_archived`: the customer is archived. `no_email`: the customer has no email address. `off_invoice`, `off_customer`, `off_workspace`: the setting that decides is off. `plan`: the plan does not include automatic emails. `all_sent`: it has had `limit`. Null while one is to come.
  One of: collecting, direct_debit, customer_archived, no_email, off_invoice, off_customer, off_workspace, plan, all_sent.

  At least 1.
  methodstringrequired
  One of: cash, cheque, card, bank_transfer, direct_debit, other.
  statusstringrequired
  A payment recorded with createInvoicePayment or createCustomerPayment has `succeeded`. One the customer made online, or a Direct Debit, is `pending` until the money clears, `failed` if it does not or if a dispute is lost, and `disputed` while the customer's bank decides a dispute. A Direct Debit collection that could not be started at all is recorded as `failed` too, with why in `notes`. Only a `succeeded` payment, less `refunded_cents`, counts towards the invoice's `paid_cents`.
  One of: pending, succeeded, failed, disputed.
  refunded_centsinteger (int64)required
  How much of the payment has been refunded: its `refunds` that `succeeded`, added up, and 0 for a payment that `failed`. Never more than `amount_cents`.
  At least 0.

  At least 1.

  `succeeded` from the moment the refund is made, though a refund through Stripe can take 5 to 10 working days to reach the customer's card or bank account. `failed` when Stripe could not get the money back to the customer, or the refund was cancelled: it no longer counts in the payment's `refunded_cents`, so the payment counts towards the invoice again.
  One of: succeeded, failed.
  sourcestringrequired
  How it was made. `app`: from TradeSender, through the business's Stripe account ("From TradeSender"). `manual`: a payment recorded by hand, refunded as a record, with no money moved ("Recorded by hand"). `stripe`: outside TradeSender, in the Stripe dashboard or by Stripe itself ("In Stripe").

  Stripe's reason for a refund that failed, such as `expired_or_canceled_card` or `lost_or_stolen_card`, when it gives one.
  referencestring or nullrequired
  The last 8 characters of Stripe's id for the refund. Null for a refund recorded by hand.
  onlinebooleanrequired
  Whether the payment went through the business's Stripe account: paid online by the customer, or collected by Direct Debit.

  referencestring or null
  notesstring or null
  For a payment that failed, why.
  paid_atstring (date-time)required
