Step 1 – Initialize PdfApi instance.

PdfApi pdfApi = new PdfApi("API_KEY", "APP_SID");

Step 2 – Upload PDF to Cloud storage.

Since all the processing of documents is within cloud, so we need to upload the PDF file to cloud storage so that we can easily process them..

pdfApi.UploadFile(fileName, System.IO.File.ReadAllBytes(Common.GetDataDir() + fileName));

Step 3 - Remove PDF page.

var apiResponse = pdfApi.DeletePage(fileName, pageNumber, storage, folder);

Alternatively, you may also try calling Aspose.PDF Cloud API using cURL commands. This approach is quite useful when you are looking to develop a solution which requires batch processing, or you need to perform PDF processing in the console.

Step 1 - Generate Access Token.

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=XXXXXX-XXXXXXX-XXXXXXXX&client_secret=XXXXXXXXXX" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Step 2 - Delete PDF from PDF file.

curl -v -X DELETE "https://api.aspose.cloud/v3.0/pdf/c4611_sample_explain.pdf/pages/2" \
