Getting 403 response when creating message with attachment using API v2 and Python

When creating messages using the Community API v2 and the Python requests library, it works fine when not trying to upload an attachment, as shown in the sanitized excerpt below.     >>> headers ...

    jeffshurtliff I got it working with the following code: 

     

    import requests

headers = {
    'li-api-session-key': 'XXXXXXXXXX_XXXXXXXXXXX_XXXXXXXXXXXX',
}

files = {
    'api.request': (None, '{\n"data":{\n"type":"message",\n"subject":"This is the message subject",\n"board":{\n"type":"board",\n"id":"KB1"\n},\n"attachments":{\n"list_item_type":"attachment",\n"items":[\n{\n"type":"attachment",\n"field":"attachment1",\n"filename":"pdf1.PDF"\n},\n{\n"type":"attachment",\n"field":"attachment2",\n"filename":"pdf2.PDF"\n}\n]\n}\n}\n}'),
    'attachment1': ('/Users/will.bowen/Documents/pdf1.PDF', open('/Users/will.bowen/Documents/pdf1.PDF', 'rb')),
    'attachment2': ('/Users/will.bowen/Documents/pdf2.PDF', open('/Users/will.bowen/Documents/pdf2.PDF', 'rb')),
}

response = requests.post('https://rsalink-stage.rsa.com/api/2.0/messages', headers=headers, files=files)

Thanks WillB! Is that error log something that I have access to view or is it only accessible to Khoros employees?

Unfortunately, it is only accessible to Khoros employees.

    Would it be possible for you to provide the full error in case it has any clues to finding out the encoding issue? Because I’ve pushed the data in the way specified in the Python requests documentation and it still errors out. Thanks!

      There's not much more to the message. 

       lithium.util.NullArgumentException: exception=org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found,lastItem=null

      Can you provide a link to the python requests doc that you mentioned? I'm going to see if I can recreate the issue, and I want to make sure I'm using the same library.

        Hi WillB,

        That was very helpful, thank you! I was able to find a Stack Overflow thread about the error which helped me realize that, despite it being in the Khoros dev docs tutorial examples, I needed to stop manually inserting the "content-type": "multipart/form-data" entry into the header when making the POST request, and just let it get defined as a multipart query on its own.

        This allowed the query to return a normal response from the Community API, albeit an error message.  See below.

        >>> response
<Response [500]>

>>> response.text
'{"status":"error","message":"Unable to parse the required Content-Body from the request.","data":{"type":"error_data","code":308,"developer_message":"Unexpected character (\'-\' (code 45)) in numeric value: expected digit (0-9) to follow minus sign, for valid numeric value","more_info":""},"metadata":{}}'

>>> response.request.body
<MultipartEncoder: {'api.request': (None, '{"data": {"type": "message", "board": {"id": "product-knowledge-base"}, "body": "This is an <b>API TEST</b> done in Python with an attached file.", "subject": "API Test with Attachment", "attachments": {"list_item_type": "attachment", "items": [{"type": "attachment", "field": "attachment1", "filename": "jive_id_bookmarklet.pdf"}]}}}', 'application/json'), 'attachment1': ('jive_id_bookmarklet.pdf', <_io.BufferedReader name='C:\\Users\\shurtj\\Downloads\\jive_id_bookmarklet.pdf'>)}>

        I'm confused by the error though because from what I'm seeing, there is no field I'm using in the JSON that requires a numeric value and where a hyphen is found, unless it thinks the Board ID field should be an integer.  But that's not what the tutorial example shows...

        These are the documents I've been referencing, per your request:

        Thanks!
