I am trying to upload a file to Bullhorn API using Make’s HTTP – Make a request module, but I keep receiving a 400 Bad Request error with the message:

{“error”:“This URL is reserved for login purposes.”}

**What I Have Tried:**

- I confirmed I am using the correct **corpToken** (blotted out in screenshot as [corpToken]) and **candidate ID**.
- The request uses the **PUT** method as required by Bullhorn API.
- The file is mapped correctly from a previous **HTTP – Get a File** module.
- I tried both appending the query parameters (`fileType` and `externalID`) to the URL and passing them in the **Query String** section.
- The **Body Type** is set to **multipart/form-data** , and the **file field** is mapped properly.

Here is the API documentation for the PUT /file request from Bullhorn (specifically the raw file not the base64-encoded file): [API Reference](https://bullhorn.github.io/rest-api-docs/#put-file).

Any help would be MUCH appreciated!
