Invoice project time

Turn the selected billable time into a DRAFT invoice for the project billing contact, grouped by grouping, and mark those entries as invoiced.

Requires the invoices:write scope (it creates an invoice), not a projects scope.
The draft is numbered when issued from the invoice API.
Entries already invoiced return 422 task_time_entry_invoiced; if the plan has used up its invoices or yearly documents, 402 limit_exceeded and nothing is created.
Sending the same batch_id again with the same request returns the same invoice; reusing a batch_id with a different project selection, grouping or entries (or after its invoice was deleted) returns 409 idempotency_key_reused.
Deleting the draft invoice releases the entries.

Client-generated opaque key (up to 255 characters; UUID v7 recommended) that makes retries safe: the first response is cached and replayed for repeats without re-executing the mutation. Reusing a key with a different body returns 409 idempotency_key_reused. See the Idempotency guide.

Length1 <= length <= 255

Factuarea-Version?string

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.
