Downloading Attachments through API

Manaswitha

I have been trying to access and download attachments to rows in a Smartsheet through API using Access token. In how many ever ways, I tried to do so, that didn't work.

However, I am able to access the attachments directly that are attached to a sheet and not to a row. Are there any different permissions to access row and sheet attachments. User permission for this Smartsheet is Admin.

The error:

{'errorCode': 1006, 'message': 'Not Found', 'refId': 'p7hg71'}

Even though there are attachments, I am getting this Not Found error.

Did anyone encounter this issue before, any help here is highly appreciated.

Thank you,

Manaswitha P.

Here is some c# code:

          PaginatedResult<Attachment> attachments = smartsheet.SheetResources.RowResources.AttachmentResources.ListAttachments(

           sheetId,     // sheetId

           rowId,      // rowId

           null       // PaginationParameters

          );

          if (attachments.TotalCount > 0)

          {

            for (int i = 0; i < attachments.TotalCount; i++)

            {

              Attachment temp = attachments.Data[i];

              Attachment at = smartsheet.SheetResources.AttachmentResources.GetAttachment(

               sheetId,         // sheetId

               (long)temp.Id      // attachmentId

              );

              if (at.AttachmentType == AttachmentType.FILE)

              {

                SiteSmartsheetLinkedFileMap map = new()

                {

                  Id = at.Id.ToString(),

                  URL = at.Url,

                  FileName = at.Name,

                  MimeType = at.MimeType,

                  RowId = rowId.ToString()

                };

                siteSmartSheet.RowAttachments.Add(map);

              }

            }

          }

The permissions should be the same for accessing Row and Sheet Attachments. I can confirm that I have accessed Row Attachments with Admin level permissions. I have written code using Javascript to both upload and download Attachments.

Hi,

Thank you for your response. Yes, I have been able to access and download the sheet and row attachments. But, after downloading, when I am trying to open the attachments, I wasn't able to.

Was getting an error as below:

Please find the code used below:

import requests

import os

# Define your Smartsheet API access token

access_token = "ACCESS_TOKEN"

# Define your Smartsheet sheet ID

sheet_id = "SHEET_ID"

# Define the endpoint for fetching sheet data

endpoint = f"https://api.smartsheet.com/2.0/sheets/sheet_id?include=attachments"

# Define headers with authorization token

headers = {

    "Authorization": f"Bearer {access_token}",

    "Content-Type": "application/json"

}

# Send a GET request to fetch sheet data

response = requests.get(endpoint, headers=headers)

if response.status_code == 200:

    rows_data = response.json()['rows']

   

    for row in rows_data:

        if 'attachments' in row:

            x = row['cells'][0]['value']  # Assuming SAP Card Number is in the first column

            row_id = row['id']

           

            # Create folder for SAP Card Number

            folder_name = f"Card_{x}"

           

            # Create folder in the file system if it doesn't exist

            folder_path = os.path.join("D:\\SAPMANAGER", folder_name)

            if not os.path.exists(folder_path):

                try:

                    os.makedirs(folder_path)

                    print(f"Folder created for SAP Card Number {x} at path: {folder_path}")

                except OSError as e:

                    print(f"Failed to create folder for SAP Card Number {x}: {e}")

           

            # Iterate over attachments and download/save them

            attachments = row['attachments']

            for attachment in attachments:

                attachment_id = attachment['id']

                attachment_name = attachment['name']

               

                # Download attachment and save it to the SAP folder

                attachment_url = f"https://api.smartsheet.com/2.0/sheets/sheet_id?rowid=row_id?include=attachments"

                attachment_response = requests.get(attachment_url, headers=headers)

               

                if attachment_response.status_code == 200:

                    attachment_content = attachment_response.content

                    attachment_path = os.path.join(folder_path, attachment_name)

                    with open(attachment_path, 'wb') as f:

                        f.write(attachment_content)

                    print(f"Attachment '{attachment_name}' downloaded and saved to folder: {folder_path}")

                else:

                    print(f"Failed to download attachment '{attachment_name}' for SAP Card Number {x}")

else:

    print("Failed to fetch sheet data")

This works for me to get a pdf using python3 and requests:

import requests

def download_pdf(url, save_path):
    response = requests.get(url)
    if response.status_code == 200:
        with open(save_path, 'wb') as f:
            f.write(response.content)
        print("PDF downloaded")
    else:
        print("Failed to download: ", response.status_code)

url = "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf"  
save_path = "downloaded.pdf"
download_pdf(url, save_path)

Most of my code for dealing with Smartsheet Attachments was done in Javascript.

Looking at your code, I see the variable attachment_url to be highly suspect. You should be getting the a JSON object from Smartsheet for the specific attachment id. Here is how it is done in Javascript:

const attachmentObj = await smartsheet.sheets.getAttachment({
    sheetId: sheetId,
    attachmentId: attachmentId
})

Then attachmentObj.url will provide a URL of the file which should look something like:

https://s3.amazonaws.com/SmartsheetB1/OBJECT_ID?response-content-disposition=attachment%3Bfilename%3DMY_FILE.PDF&Signature=%2THE_SIGNATURE%3D&Expires=EXPIRES_DATETIME&AWSAccessKeyId=ACEESS_KEY_ID 

So it should be a URL to an S3 object and will get you the PDF.

Hopefully, this will get you past your next hurdle

Hello Everyone,

I am able to download the attachments into a folder and segregating each row attachments into sub folders based on a unique column from the Smartsheet using the below Python code. Hope it should be useful for anyone who wants to work on it:

import smartsheet

import os

import requests

# Initialize Smartsheet client

smartsheet_client = smartsheet.Smartsheet('ACCESS KEY')

 

# Specify the sheet ID

sheet_id = 'SHEET_ID'

path = "FOLDER_PATH"

try:

    # Load the sheet with include discussions and attachments

    sheet = smartsheet_client.Sheets.get_sheet(sheet_id, include='attachments, discussions')

 

    print("Loaded", len(sheet.rows), "rows from sheet:", sheet.name)

   

    # Attachments that exist on the SHEET object

    for attachment in sheet.attachments:

        print("Attachment found (at SHEET-level):", attachment.name, "(attachment ID =", attachment.id, ")")

        # Add logic to process attachment here.

 

    # Attachments that exist on ROW objects

    for row in sheet.rows:

        for attachment in row.attachments:

            # print("Attachment found (at ROW-level) on Row #", row.row_number, ":", attachment.name, "(attachment ID =", attachment.id, ")")

            # Add logic to process attachment here.

            print("rowid: ", row.id, ":", attachment.id, " : ", attachment.name)

           

            response = smartsheet_client.Attachments.get_attachment(sheet_id, str(attachment.id))

           # print(response)

            if response.request_response.status_code == 200:

                url = response.url

                attachmentFile = requests.get(url)

                sapCardId = row.cells[0].value #Assuming the unique column is in the first column

                dir = path + f'/SAP_Card_Number_{sapCardId}'

                isDirExist = os.path.exists(dir)

                # remove existing directory including file(s) (tree structure)

                if not isDirExist:

                    os.makedirs(dir)

                fileName = dir + f'/{attachment.name}'

                f = open(fileName, "wb")

                f.write(attachmentFile.content)

                f.close()

            break

           

    print("---------")

 

except Exception as ex:

    print("Error:", ex)

Replace the access token and sheet id.. that should work :)

Thanks everyone for your suggestions.

Manaswitha.

Thanks for providing your solution. I will likely use it in the future.

Hint for the Future: In Smartsheet Community Discussions, you can click the paragraph symbol ¶ to the left your current typing position to format the text as code which will make much more readable and typically provides basic syntax highlighting.

For example:

#include <stdio.h>int main()
{
  printf("Hello world\n");
  return 0;
}
