Retrieving Data using FusionAuth API

[humaira.tum11]

Hello everyone,

Can someone please highlight which API functions/calls will be used to retrieve following Data

• Retrieving List of all users for a specific tenant
• Retrieving List of all users within a specific application for a particular tenant
• Retrieving tenant ID of a user based on its email ID/username only.
• Retrieving List of Tenants present in FusionAuth server
• Retrieving List of Applications associated with a specific tenant.
• Retrieving List of all the applications in FusionAuth server.

Thank you
Humaira

Hiya,

The API documentation will have answers for most of these. https://fusionauth.io/docs/v1/tech/apis/

@dan Thank you for the link. I actually did go through the API documentation. But I couldn't find API call for the following highlighted queries:
a Retrieving List of all users for a specific tenant
b Retrieving List of all users within a specific application for a particular tenant

• Retrieving List of all users for a specific tenant
  
  In here, "Retrieve a user" only retrieves a single user.
  "Search for Users", it also only retrieves the users whose Ids are provided in the query.
  its the same for following, I can't find any API calls in API documentation of Users, Registration, Login or Tenants/Application.
  • Retrieving List of all users within a specific application for a particular tenant

I have created a generic group as well, and then try to add users into that. When I retrieve the group i don't get any information regarding they are part of which groups. So It can not be used as well.

Q1 - Is it not possible retrieve these datas?
Q2 - Do we have to separately keep a database to maintain the list our self to retrieve these data on go.
(This data is required by us to create a management portal for both super admin who manages all the tenants/applications related information and for individual tenant admins who manages their own users and their related information. )

Thank you
Humaira

Hiya,

If you are using the elasticsearch search engine, you can use the admin UI and then see the elasticsearch string you'd need to set the queryString to in order to run the same search. This is the API which takes the `queryString: https://fusionauth.io/docs/v1/tech/apis/users#search-for-users

a Retrieving List of all users for a specific tenant

queryString = tenantId:64c1844b-04ef-4bc8-b4ea-3d8bf2e586e9 (or whatever your tenantId is)

b Retrieving List of all users within a specific application for a particular tenant

In this case you need to use a raw JSON query, which will be passed through to elasticsearch:

{
  "bool" : {
    "must" : [ {
      "nested" : {
        "path" : "registrations",
        "query" : {
          "bool" : {
            "must" : [ {
              "match" : {
                "registrations.applicationId" : "c6b9de0c-2f71-4019-920b-58bc2d4206fc"
              }
            } ]
          }
        }
      }
    }, {
      "query_string" : {
        "query" : "tenantId:32306536-3036-6431-3865-646430303332"
      }
    } ]
  }
}

(again, set your tenantId and applicationId.)

Note that you can't use the query JSON if you are using the database search engine. Here's how to switch between them: https://fusionauth.io/docs/v1/tech/tutorials/switch-search-engines

This data is required by us to create a management portal for both super admin who manages all the tenants/applications related information and for individual tenant admins who manages their own users and their related information.

You can build your own management portal, for sure. An alternative you may consider is creating FusionAuth users that have access to the FusionAuth application, but with limited permissions. That may or may not work for you, but you may want to evaluate it if you haven't had a chance (there are a number of predefined roles).

@dan Hi can I just check then that if I'm using the database search engine there isn't way of obtaining a list of users. We have a simple use case with a small number of users, perhaps only a single application and just a few roles within that. Getting a list of user ids that we could then enumerate for display and other purposes is something we would need to do. We would rather not have to upgrade the search engine to Elastic in order to do this but is this the only way?
Many thanks for your time,
Simon

You can definitely retrieve all users within the tenant with the database engine, just use a queryString of * and the tenant header. If you only have a few users, applications and tenants, I'd suggest using additional filtering in your application. So I'd retrieve all users for a tenant and then filter by their registrations to get the application associations.

An alternative would be to file a feature request to enhance the database engine functionality to give you what you need.

Does this help?

Hi Dan,

That is good news indeed. I think I'm just not understanding or misreading the docs https://fusionauth.io/docs/v1/tech/apis/users#search-for-users which seems to be saying use of "query" or "queryString" either only works with ES or only supports a few fields like username, email etc. I will try something like:

GET /api/user/search?queryString=*

later on today.

Many thanks for your time,

Simon

Edit: it works thanks again

Great! We have a PR out to revisit the search documentation which I just merged. So hopefully that will be clearer for folks in the future.

That sounds great. Out of interest did you mean I could filter on applicationId in the query as well? I've tried:

http://{{dockerhost}}:{{fusionport}}/api/user/search?queryString=*&applicationId=85a03867-dccf-4882-adde-1a79aeec50df

and

http://{{dockerhost}}:{{fusionport}}/api/user/search?queryString=*&registrations.applicationId=85a03867-dccf-4882-adde-1a79aeec50df

but doesn't seem to filter the results further.

Many thanks for your time,

Simon

Sorry, you'll need to filter on the application by examining the results of the search api call (which should return all users) in your application code, and filtering it in business logic.

You can't do that in the FusionAuth database search (though, again, you can with elasticsearch).

[srothery]

Ok - thanks for confirming.

@dan

Still not really clear though but at least this Q&A forum is really resourceful

[dan]

@kasir-barati Can you be more specific about your question?

Back to this comment of yours, I meant that the first line in this screenshot kinda confused me, since I thought that you're searchQuery will be searched only for these fields and not all of the existing fields if you call this this endpoint http://{{dockerhost}}:{{fusionport}}/api/user/search?queryString=*

And also I did not know that I can do something like http://{{dockerhost}}:{{fusionport}}/api/user/search?queryString=tenantId:uuid
