I'm not sure if this is possible, but i am trying to curl a post, but with a json as the parameters, like such:

curl -X POST 'https://myserver/action?params={"field1":"something","whatever":10,"description":"body","id":"random","__oh__":{"session":"12345678jhgfdrtyui"}}'

however, i keep getting some error curl: (3) [globbing] nested braces not supported at pos X

how do i do this?

The curl error is due to braces {} and square brackets [] being special curl globbing characters. Use the -g option to turn off globbing and you should be fine.

There two ways to approach this.

  1. Ensure that your JSON is properly escaped so that it can be sent as a parameter.
  2. Set the HTTP header to accept json.

For example:

curl -X POST -H "Content-Type: application/json" \ --data '{"field1":"something","whatever":10,"description":"body","id":"random","__oh__":{"session":"12345678jhgfdrtyui"}}' \ https://example.com/action

Since --data implies a POST method, "-X POST" can be removed from the command line.
@DanielStenberg true, but explicitness is better IMO.
Some call it explicit, I call it misleading and error-prone: daniel.haxx.se/blog/2015/09/11/unnecessary-use-of-curl-x
