Uploading attachment from blob plus parent parameter

English Forum Developers & API
1

I’m attempting to upload an attachment - trying both as a blob or from a URL.

Big caveat: Docs indicate you cannot add an attachment from Google Drive. Is this true whether you read the file as a blob or get the URL? If so, that greatly hinders things.

Also, the parent parameter on an attachment. Should that be the task gid?

One error I’m receiving is:
{“errors”:[{“message”:“You should specify one of parent”

Note: in code below, I either pass the name and URL of the image or a blob. This code indicates the former.

function asanaFileUpload(fileName, fileUrl, taskId, accessToken) {

  const attachURL = "https://app.asana.com/api/1.0/attachments";

  let attachment = {
    "data": {
      //file" : fileBlob,
      "name": fileName,
      "parent": taskId,
      "resource_subtype": "external",
      "url": fileUrl
    }
  }

  let options = {
    "method": "POST",
    "headers": {
      "Accept": "application/json",
      "Content-Type": "image/jpeg", //"multipart/form-data", //
      "Authorization": "Bearer " + accessToken
    },
    "payload": attachment //JSON.stringify({ data: attachment }
  };

  try {

    var result = UrlFetchApp.fetch(attachURL, options);
    var attachJSON = result.getContentText();
  } catch (e) {
    Logger.log(e);
    return null;
  } finally {

    return JSON.parse(attachJSON).data;
  }

}

Add: Searching for “You should specify one of parent” returns no results. :cry:

Try this url instead.

const attachURL  = `https://app.asana.com/api/1.0/tasks/${taskId}/attachments`

I saw that URL in the documentation somewhere and could not find it again. Do you have a link for that documentation?

That worked to create a linked attachment using the code below. How can I get it to upload the file to Asana. The image location, due to user/data sensitivity, cannot be unrestricted. The task is private to the person it is assigned to and the customer/department wants to image uploaded into Asana.

This worked - again - to create a linked attachments.

function asanaFileUpload(fileName, fileUrl, fileBlob, taskId, accessToken) {

  let attachURL = `https://app.asana.com/api/1.0/tasks/${taskId}/attachments`; 

  let attachment = {
      "name": fileName,
      "resource_subtype": "external",
      "url": fileUrl
    }

  let options = {
    "method": "POST",
    "headers": {
      "Accept": "application/json",
      "Content-Type": "image/jpeg",
      "Authorization": "Bearer " + accessToken      
    },
    "payload": JSON.stringify({ data: attachment })
  };

  try {

    var result = UrlFetchApp.fetch(attachURL, options);
    var attachJSON = result.getContentText();
  } catch (e) {
    Logger.log(e);
    return null;
  } finally {

    return JSON.parse(attachJSON).data;
  }

}

This is what worked. Image uploads correctly and is visible in the task.

Note: This is Google Apps Script

function testFileUpload() {
  const taskId = "[ENTER YOUR TASK ID]";
  const accessToken = "#/########";  //your access token
  const file = DriveApp.getFileById([ENTER AN IMAGE (JPG) GOOGLE DRIVE ID]);
  const fileName = file.getName();  //unneeded
  const fileURL = file.getUrl();    //unneeded
  const fileBlob = file.getBlob();
  const asanaResponse = asanaFileUpload(fileBlob, taskId, accessToken);
  Logger.log(JSON.stringify(asanaResponse,null,4));

}


function asanaFileUpload(fileBlob, taskId, accessToken) {

  let attachURL = `https://app.asana.com/api/1.0/tasks/${taskId}/attachments`; //"https://app.asana.com/api/1.0/attachments";

  let formData = {
       'file' : fileBlob
    }

  let options = {
    'method': 'POST',
    headers: {
      "Authorization": "Bearer " + accessToken      
    },
    'payload': formData
  };

  try {

    var result = UrlFetchApp.fetch(attachURL, options);
    var attachJSON = result.getContentText();
  } catch (e) {
    Logger.log(e);
    return null;
  } finally {

    return JSON.parse(attachJSON).data;
  }

}

Hi

I am using Power Automate to attach files to a task in Asana. I managed to get the API working using a URL and a file name with resouce_subtype set to external.

My only issue is that the images do not render in the Task.

Any idea what the issue could be as you managed to get the images rendering as per your thread above?
