}Generate draft preview PDF (pre-factura)
Generate a preview PDF for a draft invoice with a “Sin Validez Fiscal” watermark.
This is the pre-factura feature: it runs the full CFDI pipeline (normalization, XML mapping, PDF generation) without actually stamping with SAT. The generated PDF is saved and can be retrieved later via GET /invoices/draft/{id}.
Requirements:
- Draft must have at least a
clientand oneitem
What you get:
- A PDF that looks like a real CFDI invoice
- UUID shows
PREFACTURA-0000-0000-0000-SINVALIDEZ - “Sin Validez Fiscal” watermark overlay
- Useful for client approval before stamping

}Authorizations
Authentication Method: HTTP Bearer token.
The runtime requires the literal Bearer prefix — a bare token in the
Authorization header is rejected with 401 unauthorized.
Header Format: Authorization: Bearer YOUR_API_KEY
Your API key is a JWT. Live keys operate on live data (livemode: true);
test keys operate on isolated test data (livemode: false).
Get your key at: app.gigstack.pro/settings?tab=api
Errors: credential failures are answered by the authentication layer with a raw
{ "message": … } body, not the standardized envelope — 401 for a missing, malformed or
expired token, 403 for a revoked key or a plan without API access. See the Unauthorized
and AuthForbidden responses.
Path Parameters
Draft invoice ID
Query Parameters
gigstack Connect: Target team ID for multi-team access.
Requires gigstack Connect enabled on your team and shared billing account.
Also requires the multipleIssuerAccounts feature on your plan. Requests targeting a
team other than the one your API key belongs to return 403 without it.
Only API keys can use it: an OAuth access token sent with another team's id is rejected with
403 Team mismatch with OAuth token.
Optional — omit it entirely unless you are acting on another team. It deliberately
carries no example value so generated snippets do not emit ?team=undefined; when the
parameter is absent, the team is derived from your API key.
Example: ?team=team_xyz789
