Postman collection
The official collection has every API v5 endpoint with a sample body. It's the one published at docs.facturadigital.com.mx; in Postman you can try it against the sandbox without writing code.
Import the collection
- Open docs.facturadigital.com.mx.
- Click Run in Postman at the top right and pick your workspace. Postman copies the “Factura Digital API v5” collection with its folders: Conexión y Cuenta, Documentos, Validador, Kiosko Auto Facturación and Catálogos.
- Create an environment with the variables in the table below and select it before sending a request.
Variables
The collection's requests use these variables. The first two are all you need to get started.
| Variable | Value |
|---|---|
| URI | https://sandbox-app.facturadigital.com.mx/api/v5 in the sandbox, https://app.facturadigital.com.mx/api/v5 in production. |
| api_key_demo | Your current key, from Configuración › API y desarrolladores in the account of the same environment. |
| UUID | The fiscal folio you query or cancel. |
| RFC EMISOR, RFC RECEPTOR, MONTO TOTAL DEL CFDI | The CFDI data you query with GET /validator/cfdi. |
Your first request
In the Conexión y Cuenta folder, send Obtener el saldo de créditos. If the key and the URL belong to the same environment, it responds with your folio balance:
{
"message": "10 credits available.",
"balance": 10,
"code": 200
}Then try Crear CFDI via JSON in the Documentos folder. Every field of that JSON is in Create a CFDI.
