I want to check user existence in Camunda java API. I asked this question from Chatgpt and said use Camunda client library. But i not found library of that or that method. Is there a way to solve this problem? I don't want to use password checker because this way id not accurate.
The API you are looking for is the IdentityService. It provides a query method:
identityService.createUserQuery()
.userId("id")
.singleResult()
