Can we create users in Keycloak by sending a json array containing more than 2 user info?

Question

I was able to create user in Keycloak by posting a json containing only 1 user using postman.

http://localhost:8080/auth/admin/realms/master/users

But when i tried to create more than 1 user by passing a json array of more than 1 record i am getting a 500 Internal server error

[
  {
    "username": "user1",
    "firstName": "John",
    "attributes": {
      "pl_uid": null
    },
    "credentials": [
      {
        "temporary": true,
        "type": "password",
        "value": "ares2012"
      }
    ]
  },
  {
    "username": "1000195",
    "firstName": "Matt",
    "attributes": {
      "pl_uid": null
    },
    "credentials": [
      {
        "temporary": true,
        "type": "password",
        "value": "rx3o0t9f"
      }
    ]
  }
]

Is there any way by which we can send a json array to keycloak and create users there?

Answer 1

Please have a look on the discussion added in Keycloak mailing list

Just double checked the approach I suggested. I thought we had made it possible to import users into an existing realm, but that's not the case. You have to create the whole realm. It's still possible to do it this way, first create the realm and add an example user. Stop the server and run it again with:

 bin/standalone.sh -Dkeycloak.migration.action=export -Dkeycloak.migration.provider=dir -Dkeycloak.migration.realmName=<realm name> -Dkeycloak.migration.dir=<dir name>

• Replace realm name and dir name

In dir name you should then get a few json files. You can then update realm name-users-0.json to add the users you want to import.

As Bill points out the admin client could be a good alternative approach. We also have a Java client that makes it simpler to use. Have a look at the admin-client example.

So this URL can help. Have a look at this link

Another option is using partialImport API for importing users (use admin user token):

access_token=`curl --data "grant_type=password&username=admin&password=admin&client_secret=secret&client_id=admin-cli" http://localhost:8180/auth/realms/master/protocol/openid-connect/token| jq -r .access_token`

curl -X POST -H 'Accept: application/json' -H 'Content-Type: application/json' -H "Authorization: Bearer $access_token"  --data "@$PWD/myrealm-users-0.json"  http://localhost:8180/auth/admin/realms/myrealm/partialImport

Answer 2

After checking Keycloak's REST API doesn't look like bulk/batch requests for creating users are accepted. The only solution would be to send the POST request for every user.

This is not surprising, HTTP is not prepared for this kind of requests:

As HTTP does not provide proper guidance for handling batch/bulk requests and responses.

from this RESTful guide. Have a look to it, it's really usefull in REST devlopments.
