Hello All,
I’m trying to upload image using below discourse api through JAVA code:
[https://discourse.example.com/uploads.json](https://discourse.example.com/uploads.json)
by passing json in Body:
{
“type” : “avatar”,
“user\_id”: 1,
“synchronous”: true,
“file”: “Binary String”
}
But in response I’m getting below result:
{
“failed”: “FAILED”,
“message”: “undefined method `tempfile’ for #String:0x000055fc2e0a01d8”
}
Where I’m doing wrong?
Please help me.

The parameter for `file` needs to be called `files[]`. See this response for an example using Postman:
> [@Upload avatar image with API](https://meta.discourse.org/t/upload-avatar-image-with-api/55253/7):

> Okay I just verified that I got this to work. You just need to add the synchronous: true value to get the id. now that we have the id: 17 we can then make one more request:

This is my sample data

Did you get this to work? I have been trying all manner of combinations with Node.js, and cannot get this to work.
I get a 422 Unprocessable Entity error.
In [the Discourse docs](https://docs.discourse.org/#tag/Upload), it says the content-type for the request is `application/json`.
In [this post](https://meta.discourse.org/t/upload-avatar-image-with-api/55253/7), the Postman example is using `form-data`, and when I watch the composer in the Discourse Web UI, it uses a multi-part post.
Anyone know how to do this via the API without using the Ruby client?

This still doesn’t appear to be working.
This is the error I get when trying to upload an image, in binary that is.
```plaintext
Unprocessable Entity - {\"failed\":\"FAILED\",\"message\":\"undefined method `tempfile' for an instance of String\"}
```
