I want to upload a file using Request api.

I successfully tested it as a Postman program.
But I don't know how to use the invoke web service action in the power automate desktop.

Please refer to the setting method below.

[postman-Request]

let formData = new FormData();

formData.append("subject_id", ‘14’);

formData.append("uploader", el.files[0], el.files[0].name);

formData.append("id", ‘testmaster’);

formData.append("password", ‘testmaster00’);

fetch('http://testurl/', {

method: 'POST',

body: formData

})

.then((response) => response.json())

.then((data) => {

console.log(data);

});

I referred to the link below.

File upload api is not available with invoke web service action, refer to curl -x and test with rundos action.

Hello. I didn't understand the meaning of the question. What does query creation mean?
I used curl to post the created api.
The program was handled by CMD(Run DOS action).

Hi, how did you generate the curl -X POST query? what application did you use?

I succeeded in uploading the file through the test.
(I struggled with small quotes and big quotes.)
Share the successful query below.

curl -X POST %str_url% -H "Content-Type: multipart/form-data" -F "subject_id=%str_subject_id%" -F "id=%str_id%" -F "password=%str_pw%" -F "uploader=@%fileP_uploader%"

Many people look forward to being helped.
Thank you @Agnius

Hi, @Agnius
Thank you always for your answer.

I've tested it in many ways
The conclusion was that the invoke web service had no file upload function, so it kept failing.

Let's test the Run dos curl.
Thank you.

Try following this walkthrough: https://powerusers.microsoft.com/t5/Power-Automate-Desktop/Walkthrough-How-to-use-Invoke-Web-Service-with-multipart-form/m-p/981388

It presumably doesn't really work too well with file uploads, but the comments under the post also include a description of how to do it via the Run DOS command action.
