Help with http Request Post (formdata)

I just did. Still not working.


Let me know did you use JSON Input Parameter like this “{”“parentID”": ““FEF98F4245FABCCFB2DA03FDFC254717B94CC7FC3C29"”}”

and remote your headers “multipart/form-data” and try.

I just tried but i got Authorization Required output.


I gave you the valid OAuth2 token. Just verified that that token still works in postman just now. I still see that no file uploads. That’s how I’ve been checking to see if it works or not.


I have checked in the postman also with your supported pdf file. but it’s not supporting that pdf file.

AgilitteDemo.postman_collection.json (4.2 KB)

Just uploaded the postman collection that works.

This is where you select the pdf.

I responded with messages. I replied to myself and not you. Sorry. I uploaded the collection for postman that works.


Did you get a solution for the same scenario using in Uipath to upload an attachment (image).


Hi @kyqurikan

is there any idea on how to pass form-data values in http request activity ?

No solution yet?

Hello Henrik,
In this video, I use multipart/form-data:

0:20 cURL example
1:35 Send the command from POSTMAN
2:50 Implement the code in C#
4:20 Run the code
4:50 Visual Basic code VB.NET
6:20 New Process on UiPath Studio with Invoke Code
7:20 Imports Libraries in UiPath Studio
8:30 Run the Robot to Upload and Download the file

Dim client As HttpClient = New HttpClient()
client.BaseAddress = New Uri(“YOUR URL”)
client.DefaultRequestHeaders.Accept.Add(New MediaTypeWithQualityHeaderValue(“application/vnd.openxmlformats-officedocument.wordprocessingml.document”))
Dim byteArray As Byte() = Encoding.ASCII.GetBytes(“username:password”)
client.DefaultRequestHeaders.Authorization = New AuthenticationHeaderValue(“Basic”, Convert.ToBase64String(byteArray))Dim byteArray As Byte() = Encoding.ASCII.GetBytes(“username:password”)
// for OAUTH2
client.DefaultRequestHeaders.Add(“authorization”, “Bearer YOUR TOKEN”)
Dim request As MultipartFormDataContent = New MultipartFormDataContent()
request.Add(New StringContent(“tags”), “Bad”)
request.Add(New StringContent(“displayreferencetext”), “true”)
request.Add(New StringContent(“similaritythreshold”), “0.63”)
request.Add(New StreamContent(File.OpenRead(“C:\8A.docx”)), “file”, (New FileInfo(“C:\8A.docx”).Name))
Dim response As HttpResponseMessage = client.PostAsync("", request).Result
Dim strm As Stream = response.Content.ReadAsStreamAsync.Result
Dim doc As Byte()
Dim ms As MemoryStream = New MemoryStream()
doc = ms.ToArray()
File.WriteAllBytes(“C:\rpa\FORDOWNLOAD\rez.docx”, doc)

Same problem here, I need to pass the password for the API in the form-data section as a key value pair (password=ThisIsThePassword).
In Postman everything works as intended but I cannot seem to get it running in UiPath.
I also tried sending it in the Body as JSON or XML but the API does not accept this (neither UiPath nor Postman)
