# Uploading Files (multipart/form-data)

Some APIs require you to upload files, which is usually done using the multipart/form-data content type.

This can be achieved in Midio using `Http.Body.Create Form Field File` `Http.Body.Create Form Field Value`  and `Http.Body.Encode Multipart FormData` .

In the example above, we fetch an image as a buffer, which we then convert to a form field file using `Create Form Field File`. All form fields are sent as inputs to `Encode Multipart FormData`, which returns two values: a `Content-Type` header value and the encoded body. We place the header value in an object with the field value `Content-Type` and use it in the headers input when calling the API that requires a file upload. We use the `multipart/form-data` output as the body.

It is important to include the header, as it contains information about how the form data is encoded in the body.
