I am trying to add a user in keyclaok server using postman but i am not able to create.

Postman request:

first of all i got the token from keycloak:
http://54.218.218.85:8080/auth/realms/ctms/protocol/openid-connect/token

request:

  client_id=ctms-app
  grant_type=password
  username=admin
  password=password

response:

{
     "access_token": $Token,
     "expires_in": 300,
     "refresh_expires_in": 1800,
     "refresh_token":  $Token
     "token_type": "bearer",
     "not-before-policy": 0,
     "session_state": "4425bee9-c243-4d1d-89ed-7c6bcc3f37a0",

My gues, you don’t have proper permissions and that is a reason for 403 response. See 403 Error by GET REST request
