```julia
import HTTP
url = "http://localhost:8080";
open("file.json") do json; open("file.csv") do csv
headers = []
body = HTTP.Form([
"json" => json,
"csv" => csv
])
HTTP.post(url, headers, body)
end end
```
(You can check the request with e.g. `netcat -lp 8080`)
See documentation for [`HTTP.Form`](https://juliaweb.github.io/HTTP.jl/stable/public_interface/#HTTP.Form) (and [`HTTP.Multipart`](https://juliaweb.github.io/HTTP.jl/stable/public_interface/#HTTP.Multipart)), and [Julia HTTP POST request with image attachment - Stack Overflow](https://stackoverflow.com/a/66276751/5087136)

Thank you. I think it is working, but I need to add filename of csv. Please, do you know how to add filename for it?

Did you read the documentation I linked? It is explained there, and also in the SO answer.

I tried mentioned advice:
```julia
url="http://$hostname:$port/myEndPoint"
headers = ["X-User-Id" => "d5as4d654asd65a64s5dad6a"]
body = HTTP.Form(Dict(
"json" => HTTP.Multipart("data.json", open("data.json"), "text/json"),
"csv" => HTTP.Multipart("data.csv", open("data.csv"), "text/csv"),
))
res = HTTP.post(url, headers, body)
inputJson = JSON.parse(String(req.body))
```
but I still getting an error with filename:
```julia
Got exception outside of a @test
HTTP.ExceptionRequest.StatusError(400, "POST", "/myEndPoint", HTTP.Messages.Response:
"""
HTTP/1.1 400 Bad Request
Content-Type: application/json

Stacktrace:

Then you need to consult the documentation of the API you are using, maybe the names have to be something specific.

I have another issue related to multipart. It looks like PUT is not working correctly. I tried same example for POST and PUT. Same example worked for POST and didn’t work for PUT.
When I ran it in swagger or with CURL command, PUT option was working. When I used following code using HTTP.jl it was failing on side of server in function “HTTP.parse\_multipart\_form(req)”. I don’t understand why it is working with swagger, curl, but not working with HTTP.jl.
Working POST:
```julia
url = "http://$hostname:$port/datasets/csv"
headers = ["X-User-Id" => "9997773e-7e42-40d1-896b-5659a6229066",
"Content-Type"=> "multipart/form-data"]
mpdt = Vector{Pair}(undef, 2)
mpdt[1] = "configuration" => open("Upload.json")
mpdt[2] = "csv" => HTTP.Multipart("Upload.csv", open("Update.csv"), "text/csv")
body = HTTP.Form(mpdt)
res = HTTP.request("POST", url, headers, body)
```
Not working PUT:
```julia
url = "http://$hostname:$port/datasets/$(datasetId)/csv"
headers = ["X-User-Id" => "9997773e-7e42-40d1-896b-5659a6229066",
"Content-Type"=> "multipart/form-data"]
mpdt = Vector{Pair}(undef, 2)
mpdt[1] = "configuration" => open("Update.json")
mpdt[2] = "csv" => HTTP.Multipart("Update.csv", open("Update.csv"), "text/csv")
body = HTTP.Form(mpdt)
res = HTTP.request("PUT", url, headers, body)
```
Missing is boundary for HTTP.jl request. Is something wrong in my code or in HTTP.jl?
From swagger:
```julia

HTTP.jl only adds the `Content-Type` automatically for `POST`: [https://github.com/JuliaWeb/HTTP.jl/blob/255a75907a06b1340e7deac659383f15f3aa55f0/src/MessageRequest.jl#L58-L61](https://github.com/JuliaWeb/HTTP.jl/blob/255a75907a06b1340e7deac659383f15f3aa55f0/src/MessageRequest.jl#L58-L61).
I [added](https://github.com/JuliaWeb/HTTP.jl/pull/473) that code [but didn’t know if it made sense for any other request types](https://github.com/JuliaWeb/HTTP.jl/issues/489#issuecomment-567148992). You can probably make a PR and relax that to `POST` or `PUT` at least.
