Access the keycloak API from postman

Question

I have tried to access the keycloak API from the postman. but it is showing 400 bad request.

I was calling api in the below format.

http://{hostname}:8080/auth/realms/master/protocol/openid-connect/token?username=admin&password=admin&client_id=admin-cli&grant_type=password

In the headers I have set the content_type as application/x-www-form-urlencoded

I am getting the response as below.

{
    "error": "invalid_request",
    "error_description": "Missing form parameter: grant_type"
}

Can any one help me.Any help will be appreciated. thanks in advance

Answer 1

A bit late for this question, but you did ask about postman and not curl. So you have to put the options in x-www-form-urlencoded

Answer 2

You call API through POST client

URL - http://localhost:8080/auth/realms/Demo/protocol/openid-connect/token

So here in above url i am using Demo as my realm instead of master.

ContentType - "Content-Type":"application/x-www-form-urlencoded"

Params:

{
"client_secret" : "90ec9638-7647-4e65-ad20-b82df3341084",
"username" : "ankur",
"password" : "123456",
"grant_type" : "password",
"client_id": "app-client"
}

Set Header as below

Data Need to be passed as shown below
