Unire documenti PDF
Combinare più documenti PDF in uno solo, nell’ordine in cui vengono forniti.
Combinare più documenti PDF in uno solo. I file vengono uniti esattamente nell’ordine in cui compaiono nella richiesta, così si controlla la sequenza finale delle pagine. In una sola chiamata è possibile inviare tutti i file necessari. L’API è stateless: il documento viene elaborato nella regione e non viene mai memorizzato.

Autenticazione
Autenticare ogni richiesta con la chiave API segreta nell’intestazione
X-API-Key, tramite HTTPS. Le chiavi si creano e si gestiscono dalla
dashboard. Vedere
Autenticazione per i dettagli.
Richiesta
L’endpoint accetta un corpo della richiesta multipart/form-data.
filefile[]requiredI documenti PDF di input, inviati come parti file ripetute. Fornirne almeno
uno; in una sola richiesta è possibile inviare tutti i file necessari. I
documenti vengono uniti esattamente nell’ordine in cui le parti compaiono
nella richiesta. Vedere Lavorare con i
file per sapere come inviare più parti file.
Esempi
Unire tre PDF in uno solo, in ordine:

-F file=@chapter-2.pdf \

In caso di successo, la risposta è 200 OK e il corpo contiene il PDF unito:
HTTP/1.1 200 OK
Content-Type: application/pdf
Content-Length: 96124L’output è un unico PDF il cui numero di pagine è la somma delle pagine dei documenti di input, disposte nell’ordine della richiesta. Scrivere il corpo direttamente in un file, come fanno gli esempi qui sopra; dalla nostra parte non viene memorizzato nulla.
Errori
Le richieste non riuscite restituiscono un corpo application/problem+json.
L’errore più frequente su questo endpoint è un 400, restituito quando una
delle parti file non è un PDF leggibile. L’oggetto errors nomina il campo:
{
"type": "https://www.pdfblocks.com/docs/api/v1/error/400",
"title": "One or more validation errors occurred.",
"status": 400,
"errors": {
"file": ["Could not parse the PDF document. The file may be invalid or corrupt."]
}
}Una X-API-Key assente o non valida restituisce un 401. Vedere
Errori per tutti i codici di stato e la forma completa della
risposta.
