I'm trying to send a file in Postman native to test our API, but I can't get it sent. I've set Request method POST, chosen BODY and added a file (using the file selector) and given the file the key I want it to have. I've also added another key-value (string), which gets sent. This is the request:
POST /api/user/1901594/17406/foto HTTP/1.1
Host: hidden.domain.com
tp-api-token: eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpZCI6ImF4a3Jpc3RpYW5zZW4iLCJ0dGwiOjE1NTYwNDQ0NDh9.7MAp43_4jnPM_QQluc2Ozx-QBowjCIqQzJ8sn9Y7HG0
cache-control: no-cache
Postman-Token: 8c14c293-f769-4391-90a3-c070cba1393a
Content-Type: multipart/form-data; boundary=----
WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="foto"; filename="C:\Users\ander\Downloads\bilder tilhenger\DSC_0178.JPG
Content-Disposition: form-data; name="unikID"
asdf2398
------WebKitFormBoundary7MA4YWxkTrZu0gW--
As you can see the filename is added to the request, but not the actual file itself (it should be, shouldn't it?)
Is this a bug, or am I doing something wrong?
Nothing wrong with the Postman request. It was the PHP extension php-fileinfo who wasn't installed on our new server.

The eBay CSV Manager enables to upload a CSV file to mark all paid and sent items as sent in eBays seller tool. My Excel Macro creates such a CSV file. Now, I want to upload this file via HTTP Post Request.
In eBays CSV Manager manual they say:
Files can only be uploaded via Token. This Token has to be send with the file every upload. It is virtually the key for the entry to the CSV Manager.
I already have the Token.
It goes on to say that
a HTTP Post request has to be sent to the eBay CSV Manager Server to upload the file via script. The HTTPS connection has to be started and the data has to be send together with the Token to the CSV Manager web adress https://bulksell.ebay.com/ws/eBayISA...ExchangeUpload
eBay has an example for the request in its CSV Manager manual:
POST /path/to/upload/script HTTP/1.0
Connection: Keep-Alive
User-Agent: My Client App v1.0
Host:
https://bulksell.ebay.com/ws/eBayISA...ExchangeUpload
Content-type: multipart/form-data;
boundary=THIS_STRING_SEPARATES
Content-Length: 256
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="token"
12345678987654321
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="file";
filename="listings.csv"
Content-Type: text/csv
... contents of listings.csv ...
--THIS_STRING_SEPARATES
The explanation of the example is:
State which method has to be applied to the ressource:
POST /path/to/upload/script HTTP/1.0
Connection type, user-agent and information to the host:
Connection: Keep-Alive
User-Agent: My Client App v1.0
Host:https://bulksell.ebay.com/ws/eBayISA...ExchangeUpload
Header with information to the content and the lenght of the file:
Content-type: multipart/form-data; boundary=THIS_STRING_SEPARATES
Content-Length: 256
Safety Token and content to be uploaded:
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="token"
12345678987654321
--THIS_STRING_SEPARATES
Content-Disposition: form-data; name="file"; filename="listings.csv"
Content-Type: text/csv
... contents of listings.csv ...
--THIS_STRING_SEPARATES
How to do the HTTP Request and how to integrate it to the VBA Code?
The concept of REST API is that you post a data file to the API end point. You need to use one of microsoft http add-on to conscruct the payload which contains the header and body and post it to the require API.
You would have multi part in your macro to achieve this function
A login function where you would store the token
A body constructor where you would read your excel data and transform it into a json format.
A header constructor
A post function where post the relevant data to the gateway api using the microsoft http document handler.
But if you are planning to send the CSV as data then its best to write a vbscript to quickly post the file to the API.
As a system administrator, I want to fetch all the libraries from my organization. To achieve my goal I tried to use the request to GET /services/data/v48.0/query/?q=SELECT+Id+FROM+ContentWorkspace.
But I did not get private 'ContentWorkspaces'.
Another problem that I faced was trying to create a file in user`s private library.
Example 1
POST /services/data/v48.0/sobjects/ContentVersion/
--boundary_string
Content-Disposition: form-data; name="entity_content";
Content-type: application/json
{"PathOnClient":"FILE.txt", "OwnerId":"0051v000006lmLuAAI", "FirstPublishLocationId":"0581v000000dacWAAQ"}
--boundary_string
Content-Type: application/octet-stream
Content-Disposition: form-data; name="VersionData"; filename="FILE.txt"
Binary data goes here.
--boundary_string--
Example 2
POST /services/data/v48.0/sobjects/ContentVersion/
--boundary_string
Content-Disposition: form-data; name="entity_content";
Content-type: application/json
{"PathOnClient":"FILE.txt", "OwnerId":"0051v000006lmLuAAI"}
--boundary_string
Content-Type: application/octet-stream
Content-Disposition: form-data; name="VersionData"; filename="FILE.txt"
Binary data goes here.
--boundary_string--
Is it possible to achieve everything that I mentioned above using the system admin token with 'Query All Files' perms or it is impossible?
I am trying to send a post request though an api. The call requires:
content-type: multipart/form-data; boundary=[boundary_number]
I have used Charles HTTP proxy to watch see what headers/content I need to send.
My Request: (basically copied from Charles' multipart section)
--324a08fa-6b58-424a-a1ad-691123d9d04b
Content-Disposition: form-data; name="message[body]"
Content-Transfer-Encoding: binary
Content-Type: text/plain; charset=utf-8
Content-Length: 5
Text!
--324a08fa-6b58-424a-a1ad-691123d9d04b--
** My Headers:**
My Result:
When I post this in postman, the response just displays 'Loading'
I can't seem to satisfy the content I was wondering if anyone can point me in the right direction.
Any help would be greatly appreciated!
Cheers!
The response is not as expected because the Content-Length of HTTP request body is incorrect. It should be 240, not 238.
For HTTP request in Charles screenshot, the message[body] data is qqq, which is also indicated by Content-Length: 3. However, in your HTTP request in postman, the message[body] data is Text!. While its own Content-length is correct (5), the Content-length of the whole request body is not changed accordingly -- it's still 238, which should be increased to 240.
I am using RestSharp to upload multi-part messages (basically, form data with a file attached at the end). The receiving service seems to require that I specify the Content-Transfer-Encoding header on each part or I get a 400 error on the POST.
I can't find any way in RestSharp to set this, or to specify "headers" that are actually inside the body of the parts. What I need to produce is a payload that looks like this:
POST http://server/object/create HTTP/1.1
User-Agent: RestSharp/105.2.3.0
Content-Type: multipart/form-data; boundary=-----------------------------28947758029299
Host: server:8080
Content-Length: 540
-------------------------------28947758029299
Content-Type: application/xml;charset=US-ASCII
Content-Disposition: form-data; name="form"
Content-Transfer-Encoding: 8bit
<form>this is some form data in XML format</form>
-------------------------------28947758029299
Content-Disposition: form-data; name="1.eml"; filename="1.email"
Content-Type: application/octet-stream; charset=ISO-8859-1
Content-Transfer-Encoding: binary
This is arbitrary file content to attach to the form.
-------------------------------28947758029299--
So far, this is what I've got (I'm prototyping in PowerShell but the results are identical in C#):
$request = New-Object RestSharp.RestRequest("iss", [RestSharp.Method]::POST)
$request.AddParameter("application/xml;charset=UTF-8", $form, [RestSharp.ParameterType]::RequestBody) | Out-Null
$request.AddFile("att.txt", "C:\Development\att.txt", "application/octet-stream; charset=ISO-8859-1") | Out-Null
$response = $rest.Execute($request)
which does everything I need except the Content-Transfer-Encoding part.
Is this possible with RestSharp, or should I drop down to use the HTTP client directly?
I am trying to create an object via postman rest client with the following request. It gives the below-mentioned error. What could be the reason for this? Can anyone help me to fix this?

You have an error in your boundary:
It need "--"(2 dash) more than the header so:
Content-Type: multipart/form-data;boundary=----WebKitFormBoundaryE19zNvXGzXaLvS5C
Should be:
Content-Type: multipart/form-data;boundary=------WebKitFormBoundaryE19zNvXGzXaLvS5C
Apparently for Post request
From:
HTTP POST with HttpWebRequest
The file or content must be the last field in the form. Any fields below it are ignored.
http://docs.aws.amazon.com/AmazonS3/latest/dev/HTTPPOSTForms.html
Yours is not last. It's followed by other form fields, and presumably this is confusing S3 into thinking you have more than one file. Granted, the "ignored" in the docs is not entirely consistent with my explanation, but that could be a side effect of uploading a small file, if that's what you're doing... fields that begin within about the first 20K of the upload may not always be ignored if they come after the file.
I believe your boundary values need to be prefixed with -- for each entry and the last boundary value needs to be suffixed with -- as follows (also as mentioned before, file needs to go last):

I was having the same error, the problem for me was that indeed the file was "empty".
I had the request saved for a long time, and maybe I missplaced the file in my computer, and the reference Postman had was broken (I haven't seen message in the console of Postman though)
Adding again the file solved it. No more "POST requires exactly one file upload per request." error message.
I am not sure how that would translate to the HTTP code request being used by all the answers here, and I don't think that copying the HTTP code here will help, since I believe POSTMAN strips the actual contents of the file, but to give more info, I have it like this:
----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="sample-mp4-file-small.mp4"
Content-Type: <Content-Type header here>
