Hi rubbermeetsrd,

🙂 What are you expecting? You correctly declared "application/json" format, but by default how fetch is formatting the passed map? 🤔 Isn't it a form encoding? 😉

Hope this gives direction.

What am I expecting? I am expecting the pdf file to move from one folder to another which it does in Postman.

In Postman, the body format is raw. I am not familiar enough with fetch calls to say whether they are encoded forms or not. This is the API call working in Postman (access token is whited out). When I brought up the move_v2 api call, the template was set up as a raw body which worked.

  I don't know what you mean 'raw body', but your 'template' seems correct. It should work. Why are you NOT calling 'move_v2' in the same way? 🤷 Take a look on your OP. Is it the same or not exactly? 🙂

    rubbermeetsrd The /2/files/move_v2 endpoint is an "RPC" style endpoint, meaning it expects the parameters as JSON in the request body. The "request body: could not decode input as JSON'" error you're getting indicates that the request body did not contain valid JSON, and so the Dropbox API was unable to understand it.
    
    You'll need to debug your code to make sure you're sending valid JSON in the request body. As Здравко noted, make sure you check which code you're running, as the code in your screenshot does not match the code in your original post. Specifically, one does convert the parameters to JSON using JSON.stringify, and one does not.
