Question

How to order documents for Manual Review if they are uploaded via API?

Answer

If you define the index parameter for each file, then you will get the same order as the file's array. Here is the sample:

{
  "files": [
    {
      "index": 0,
      "imageProcessingOptions": {
        "autoCrop": "Default",
        "autoOrientation": "Default"
      },
      "registrationParameters": [
        {
          "key": "Document",
          "value": "0"
        }
      ]
    },
	{
      "index": 1,
      "imageProcessingOptions": {
        "autoCrop": "Default",
        "autoOrientation": "Default"
      },
      "registrationParameters": [
        {
          "key": "Document",
          "value": "1"
        }
      ]
    },
	{
      "index": 2,
      "imageProcessingOptions": {
        "autoCrop": "Default",
        "autoOrientation": "Default"
      },
      "registrationParameters": [
        {
          "key": "Document",
          "value": "2"
        }
      ]
    }
  ]
}

And the result:
