docs.facturia.cl
Chile's e-invoicing API.
You POST a small JSON object. We take a folio from a real CAF, build and sign the XML, transmit it to the SII, follow it to a terminal state, render the PDF and tell you what happened. We also receive the DTEs your suppliers send you, keep your Registro de Compras y Ventas current and compute your F29.
Start here
What Facturia is, your first invoice in the sandbox, and the four concepts everything else hangs off.
Authentication
sk_test / sk_live keys, scopes, the empresa allowlist, rotation and rate limits.
Issuing
Creating 33/34/39/41/46/52/56/61 documents, previews, PDF and XML artifacts, and the map of SII states.
Reception
The exchange casilla, the documents your suppliers send you, and the 8-day window where silence accepts.
Tax
RCV sync, characterisation, the F29 proposal and filing it.
Webhooks
HMAC signatures, retries with jitter, 12 months of replay, and the event catalog.
MCP / AI
Connecting Claude or any other agent to mcp.facturia.cl: OAuth, the tool catalog and confirmations.
API reference
The 99 paths of /v1, generated from the OpenAPI 3.1 document we publish.
Errors
The error envelope, the types, the SII rejection codes and the request_id.
The sandbox is free forever and never touches the SII. You can build the whole integration before you own a certificate. This reference is public and needs no login.
