Hello,
I have to create a total of 300 users in camunda with default password and default group. Is it possible via SQL Query or REST API ?
Have you some example ?

Thanks

Hi @oronzo_lezzi,

this is the REST Api call to create a user: https://docs.camunda.org/manual/7.12/reference/rest/user/post-create/

And with this call you can add the user to a group: https://docs.camunda.org/manual/7.12/reference/rest/group/members/put/.

If you put these requests into a client of your choice and add a loop around it you can easly create 300 users.

Hope this helps, Ingo

Hi @oronzo_lezzi,

the group has to exist in the database. After you create it (https://docs.camunda.org/manual/7.12/reference/rest/group/post-create/), you can add members to it.

Hope this helps, Ingo

Thanks, was a my mistake in the REST API.
So I must to write code to insert all the users and put then in a group. I cannot use only one API call to create all the users as you write in the first response.
Is it correct ?
Thanks
O.

Hi @oronzo_lezzi,

yes, your assumption is correct.

My first understanding was, that all users belong to the same (existing) group.

Cheers, Ingo
