}Descargar el logo del emisor
Devuelve el archivo tal como se subió, con su Content-Type. 404 si el contribuyente no tiene logo, que es distinto de no existir.
Scope de API key: taxpayer:read. Una key sin ese scope recibe 403 API_KEY_INSUFFICIENT_SCOPE, aunque el rol de quien la creó lo permita: el permiso efectivo es la intersección de los dos.

}Authorizations
API key de integración. El modo va en el prefijo: emi_test_ opera contra homologación, emi_live_ contra producción. Después, 64 hexadecimales.
Headers
El producto que origina el pedido (inmos, por ejemplo). Opcional, sólo con API key. Formato ^[a-z0-9-]{1,32}$; otro valor da 400 INVALID_INPUT. Queda en el comprobante, en el consumo y en el registro de pedidos.
Con una key sin producto es sólo atribución: no autoriza ni restringe nada. Con una key atada a un producto el pedido se etiqueta con el de la key aunque no mandes la cabecera, y si mandás otro valor la respuesta es 403 API_KEY_PRODUCTO_DISTINTO.
^[a-z0-9-]{1,32}$"inmos"
Path Parameters
Response
El archivo, con su Content-Type real. No es JSON: son los bytes de la imagen, listos para un <img src>.
The response is of type file.
