Unable to add record via API

Hi,

I'm trying to add a record into a Zoho Creator application i've created from a Zoho CRM custom function. Here's the call i'm making:

paramsmap=map();

paramsmap.put("authtoken","my correct auth token that i know works");

paramsmap.put("scope","creatorapi");

paramsmap.put("Account_Name","My Account");

info paramsmap;

info url;

** I'm replacing "myuser" in the call and "my correct auth token" with the correct values.

The paramsmap value is:

{"authtoken":"my correct auth token that i know works","scope":"creatorapi","Account_Name":"My Account"}

The response i'm getting is:

The request had bad syntax or was inherently impossible to be satisfied.

Any idea what the issue is?
