Void an invoice · Ownrecord docs

Voids a draft or an open invoice.

A draft is set aside without a number; its pending invoice items go back to waiting for the customer's next invoice.
An open invoice keeps its number (numbers are never reused) and its PDF; its ledger posting is reversed, and credit balance it used goes back to the customer.

Paid invoices aren't voided: they are corrected with a credit note. Emits invoice.voided. Financial tier: an approval policy may require a second person; dry-run it first.

Errors

Code	HTTP status	When	What to do
`validation_failed`	400	`id` isn't an invoice ID.	Fix the fields listed in `details.issues` and send the request again.
`resource_not_found`	404	This brand has no such invoice in this mode (invoices belong to one brand and one mode).	Check the ID and that your credentials are scoped to the right organization, entity, brand and mode.
`invoice_status_invalid`	409	Only drafts and open invoices are voided; a paid invoice is corrected with a credit note.	Check the invoice's `status` (`details.status`) and what it still allows (`details.allowed_actions`). Drafts are edited and finalized; open invoices are sent, paid, voided or marked uncollectible; paid and void invoices don't change (corrections are credit notes).
`version_conflict`	409	The invoice changed since `expectedVersion`, or at the same moment; read it again and retry.	Fetch the object again and retry the change.
`idempotency_key_reused`	409	The idempotency key was used before for another request.	Use a new Idempotency-Key for a different request, or resend the original request unchanged.
`approval_required`	202	The organization's approval policy needs a second person for this; nothing changed yet.	Nothing ran yet. An approver reviews `approval.summary` and the dry-run result in the console (`approval.approveUrl`). Poll `GET /approvals/{id}` or watch for the `approval.resolved` event; sending the same request again with the same Idempotency-Key returns the same approval.
`approval_rejected`	409	The same request was sent again after it was rejected.	Read the reason in `details.approval.rejection`. To try again, send a new request with a new Idempotency-Key.
`approval_expired`	409	The same request was sent again after its approval request expired.	Send the request again with a new Idempotency-Key to create a new approval request. Requests expire after 72 hours.
`stale_approval`	409	The approved request could no longer run as requested.	Check the current state (`details.approval.failure` says what failed), then send a new request with a new Idempotency-Key.
`scope_required`	400	The request names no brand (an org or entity key without `Ownrecord-Brand`).	Call the operation with credentials or a target at its level: an organization, a legal entity, a brand or the platform (`details.required_scope`).
`permission_denied`	403	You can't change this brand's invoices (`invoices:write`: finance, owners and admins).	Ask an organization owner or admin for a role or scope that allows this action.
`livemode_not_allowed`	403	You have no live-mode access, so you can't use live invoices.	Use test mode, or credentials for the target's mode. Developers need live access granted by an organization owner or admin.

It can also return these common errors: api_version_unsupported, invalid_json, unsupported_media_type, authentication_required, api_key_invalid, idempotency_key_required, idempotency_in_progress, approval_policy_denied, rate_limited, internal_error.
