Automate Mis Comprobantes with a workflow

  Every weekday at 8:00, Buenos Aires time

  Step 1

  Get the comprobantes recibidos for your CUIT with a Fecha de Emisión in the last 7 days.

  Step 3

  Post each one, with issuer, Cód. Autorización, IVA and Imp. Total, to your ERP's webhook.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get comprobantes recibidos” would look like.

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

Mis Comprobantes’s own options

ARCA offers web services for issuing electronic invoices and for checking a comprobante through Constatación de Comprobantes, and some of its services need special authorizations and agreements with ARCA. Its web services catalog lists no service for the Mis Comprobantes lists: you read them in the browser and download them as Excel, PDF or CSV.

Signing in to Mis Comprobantes

ARCA signs you in to Mis Comprobantes with your CUIT and Clave Fiscal, and the service must first be enabled for you in the Administrador de Relaciones. When you act for a company, you sign in with your own CUIT and choose the company's. With Fous you sign in once through ARCA's own sign-in with your own Clave Fiscal: it is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Enable the service first

Mis Comprobantes does not appear in Mis Servicios until it is added in the Administrador de Relaciones de Clave Fiscal. Until then a method has nothing to open.

Your own CUIT, the company's data

To read a company you administer, you sign in with your own CUIT and choose the company's CUIT inside ARCA. A method takes the CUIT to read as an input.

Emitidos and recibidos are separate lists

Each list is queried on its own with a Fecha de Emisión range. Comprobantes emitidos show the receiver's Tipo Doc., Nro. Doc. and Denominación; recibidos show the issuer.

Foreign-currency invoices keep their currency

A comprobante in foreign currency is shown in its original currency, with Moneda and Tipo Cambio in its row. Convert to pesos before you compare totals with your books.
