Preview the seat charge of adding a company

Preview the prorated per-seat amount for adding or activating managed companies, computed from the master tenant's Stripe upcoming invoice, without charging.

Use count (≥1) to preview a batch, or company_ids for a coverage-aware preview: companies still covered for the current period cost 0 (already_covered: true).
amount is in the currency's minor units; requires_payment_method is true when no payment method is on file.

Query Parameters

count?|

Número de empresas hijas que se activarían en bloque (≥1, default 1).

Range1 <= value <= 1000

company_ids[]*array<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.
