}Create an invoice
Bidirectional: outbound (firm bills client) or inbound (vendor bills firm). Outbound supports fromUnbilled: true to pull unbilled time entries and uninvoiced reimbursable expenses atomically.
Supports one selected organization via organizationId. Omit it to use the key’s organization. HQ descendant access requires an active acting attorney with hq:view_child_orgs, cases:view, cases:view_all, hq:view_all_cases, accounting:view, accounting:view_all, hq:view_all_accounting, invoices:view, hq:manage_child_orgs, invoices:create. Existing key scopes still apply. The selector requires an integration API key; legacy partner/OIDC routing is unchanged. Repeat the selector on every cursor page, related mutation, upload completion, and detail/download request. Mutation key scopes, idempotency, revisions, and resource-specific eligibility still apply. See HQ authorization.
Requires the billing:write scope. Mutations require an X-Idempotency-Key header (responses are stored for replay; reusing a key with a different request returns 409 IDEMPOTENCY_CONFLICT). Rate tier: write.
