details[].lineNumber es el número de línea (1..N, en orden estable) de cada ítem. Úsalo como nroItem al emitir una Nota de Crédito/Débito de sector 47/48: el returnedDetails[].nroItem (y el overlay ICE del 48) referencian la línea original por este número. Solo el detalle de una factura individual (GET /invoices/{id} o /cuf/{cuf}) incluye details; los listados (GET /invoices, /search) no lo traen.

​

Tambien puedes obtener una factura usando su Codigo Unico de Factura (CUF):

  -H "X-API-Key: YOUR_API_KEY"

const response = await fetch(
  'https://sandbox.cucu.bo/api/v1/invoices/cuf/2872F7294502332E637FABFBC3654EA82202AD48E0969F14EBEB8AF74',
  { headers: { 'X-API-Key': 'YOUR_API_KEY' } }
