AzureDevops API: Image not uploaded

I use the method

POST

"https://dev.azure.com/{organization}/{project}/_apis/wit/attachments?uploadType=Simple&fileName={filename}&api-version=5.0"

headers

headers = {
            "Accept": "application/json",
            "Content-Size": str(os.path.getsize(file_path)),
            "Content-Type": "application/octet-stream",
}

I get a successful response and a link to the image, but the image is 'broken', white square instead of original image

enter image description here

Solution

  • We can call this API first to upload the attachment image with binary file content and then sent this request to add the uploaded file as an attachment of a work item.

    Here is the sample Python script for your reference which works from my side.

    import base64
import json
import requests

# Define your Azure DevOps organization, project, and personal access token
organization = "YourADOOrgName"
project = "TheProjectName"
personal_access_token = 'XXXXXX'

# Encode the personal access token in base64
base64_pat = base64.b64encode(f':{personal_access_token}'.encode('utf-8')).decode('utf-8')

# Define the path to your image file
image_file_path = "C:/Users/Alvin/Desktop/testImage.png"

# Read the binary contents of the image file
with open(image_file_path, "rb") as image_file:
    image_file_bytes = image_file.read()

# Define the URL for uploading the attachment
upload_url = f"https://dev.azure.com/{organization}/_apis/wit/attachments?fileName=testImage.png&uploadType=Simple&api-version=7.1-preview.3"
headers = {
    "Authorization": f"Basic {base64_pat}",
    "Content-Type": "application/octet-stream"
}

# Make the API request to upload the binary file
response = requests.post(upload_url, headers=headers, data=image_file_bytes)
upload_response = response.json()

# Get the attachment URL from the upload response
attachment_url = upload_response['url']

# Define the URL for updating the work item
work_item_id = 2308
wit_url = f"https://dev.azure.com/{organization}/{project}/_apis/wit/workitems/{work_item_id}?api-version=7.1-preview.3"

# Define the body for the work item update request
attachment_body = [
    {
        "op": "add",
        "path": "/relations/-",
        "value": {
            "rel": "AttachedFile",
            "url": attachment_url,
            "attributes": {
                "comment": "Add a test image attachment from Python script"
            }
        }
    }
]

# Make the API request to update the work item
headers["Content-Type"] = "application/json-patch+json"
response = requests.patch(wit_url, headers=headers, json=attachment_body)
update_response = response.json()

# Print the response of the work item update request
print(json.dumps(update_response, indent=4))
