Add User API returning 400 response

Hi, is it possible to use my authorization token from different environments? (Programmatic) API calls from my application are working from my application server, but not from my local environment.

Sample request:
Headers:
“Accept”: “application/json”
“Content-type”: “application/json”
“Authorization”: “Bearer <intercom_authorization_token>”

Request Body:
email":"email@email.com”, “name”:“null null”, “custom_attributes”:{<various custom attributes in key/value format}, “id”:"", “signed_up_at”:1581444122}
