Merge two password protected documents in a specified order

Using 🤖/document/merge, you can merge several pdf documents together in a single file.

There's no need to worry if you're handling password protected documents either, as you can simply specify an array of passwords to the input_passwords parameter, which will be used for each document.

To specify an order for the documents, use the "as" syntax, as shown in the demo below.

Step 1:

Filter files

We let you reject, or direct files against different encoding Steps.Learn more

first_document.pdf

application/pdf – 14 KB

"first": {
  "use": ":original",
  "robot": "/file/filter",
  "result": true,
  "accepts": [
    [
      "${file.basename}",
      "==",
      "first_document"
    ]
  ]
}

/file/filter

This bot directs files to different encoding Steps based on your conditions

      "==",
      "second_document"
    ]
  ]
}
