We frequently use tenant impersonation via the tenant list. However, we want to call it directly via our dashboard, as we have a client list there and want to avoid the detour via your tenant list in the SaaS module.
Since the source for this is not public, I have unfortunately not been able to figure out how to implement this. Can you tell me how I should do this?
I want exactly the same behavior. Click on a link on the tenant, then the pop-up should open to enter the username, etc.
Thanks, Adrian

To implement tenant impersonation directly from your dashboard in an ABP Blazor Server application (v8.3.4), you should use the impersonation APIs provided by the ABP Account module. The impersonation feature allows you to impersonate a tenant or user, and the same backend logic is used by the SaaS module's tenant list.
Here's how you can trigger tenant impersonation from your own UI:
Ensure Permissions:
- The current user must have the required permissions:
AbpIdentity.Users.Impersonation
for user impersonation andSaas.Tenants.Impersonation
for tenant impersonation.
- The current user must have the required permissions:
Use the Impersonation API:
- The Account module exposes endpoints for impersonation. You can call these endpoints from your dashboard.
- For tenant impersonation, use:
POST /api/account/impersonation/tenant
with a payload like:
{ "tenantId": "GUID of the tenant" }
- For user impersonation:
POST /api/account/impersonation/user
with a payload like:
{ "userId": "GUID of the user", "tenantId": "GUID of the tenant (optional, for host users)" }
Open the Impersonation Dialog:
- To replicate the pop-up behavior, you can create a modal dialog in your Blazor dashboard that collects the username (or user selection) and then calls the impersonation API.
- After a successful API call, the backend will return a URL for impersonation. Redirect the browser to this URL to complete the impersonation process.
Example: Blazor Button to Impersonate Tenant
@inject HttpClient Http @code { async Task ImpersonateTenant(Guid tenantId) { var response = await Http.PostAsJsonAsync("/api/account/impersonation/tenant", new { tenantId }); if (response.IsSuccessStatusCode) { var result = await response.Content.ReadFromJsonAsync<ImpersonateResultDto>(); NavigationManager.NavigateTo(result.ImpersonationUrl, forceLoad: true); } } }
- UI/UX:
- You can use a Blazor modal dialog to prompt for the username or user selection, then call the appropriate API as above.
This approach gives you the same impersonation behavior as the SaaS module, but triggered from your own dashboard.

Is there no way to call up a corresponding service method from the SaaS module directly from my AppService?

hi
Add a http form in your Blazor page.
Submit
ImpersonationForm
will login the tenant admin user.<form method="post" action="Account/ImpersonateTenant" id="ImpersonationForm"> <input type="hidden" name="TenantId" value="Your_Tenant_Id"> <input type="hidden" name="ReturnUrl" value="Your_ReturnUrl"> <input type="hidden" name="TenantUserName" value="Your_Tenant_UserName"> </form>

I mean something like this:
await AccountAppService.ImpersonateTenantAsync()
Is this possible?

hi
No, you can only submit the form.
<form method="post" action="Account/ImpersonateTenant" id="ImpersonationForm"> <input type="hidden" name="TenantId" value="Your_Tenant_Id"> <input type="hidden" name="ReturnUrl" value="Your_ReturnUrl"> <input type="hidden" name="TenantUserName" value="Your_Tenant_UserName"> </form>

Unfortunately, I haven't been able to get it to work yet. I tried three different variations. With the first two, I get the error message: “There is no user with username: admin!” But this user does exist (it also works when I use impersonation in the other way).
I don't see any error messages or other indications in the log file.
The third option is the one suggested above by the AI bot. But there I get a 404 error.
This is the code:
<form method="post" action="Account/ImpersonateTenant" id="ImpersonationForm1"> <input type="hidden" name="TenantId" value="@SelectedTenantId" /> <input type="hidden" name="TenantUserName" value="@SelectedTenantUserName" /> </form> <form method="post" data-ajaxForm="false" action="Account/ImpersonateTenant" id="ImpersonationForm2"> <AntiforgeryToken /> <input type="hidden" name="ReturntId" value="@SelectedTenantId" /> <input type="hidden" name="TenantUserName" value="@SelectedTenantUserName" /> <input type="hidden" name="ReturnUrl" value="" /> </form>
// Impersonation variant 1 private async Task SubmitImpersonationForm1(Guid tenantId) { Logger.Log(LogLevel.Information, "Start impersonation variant 1"); SelectedTenantId = tenantId.ToString(); SelectedTenantUserName = "admin"; await JSRuntime.InvokeVoidAsync("submitForm", "ImpersonationForm1"); } // Impersonation variant 2 private async Task SubmitImpersonationForm2(Guid tenantId) { Logger.Log(LogLevel.Information, "Start impersonation variant 2"); SelectedTenantId = tenantId.ToString(); SelectedTenantUserName = "admin"; var tokens = Antiforgery.GetAndStoreTokens(HttpContextAccessor.HttpContext); var requestToken = tokens.RequestToken; await JSRuntime.InvokeVoidAsync("submitFormWithAntiforgeryToken", "ImpersonationForm2", $"/Account/ImpersonateTenant", requestToken); } // Impersonation variant 3 private async Task SubmitImpersonationForm3(Guid tenantId) { Logger.Log(LogLevel.Information, "Start impersonation variant 3"); //var response = await Http.PostAsJsonAsync("/api/account/impersonation/tenant", new { tenantId }); var response = await Http.PostAsJsonAsync("https://localhost:44367/api/account/impersonation/tenant", new { tenantId }); if (response.IsSuccessStatusCode) { //var result = await response.Content.ReadFromJsonAsync<ImpersonateResultDto>(); //NavigationManager.NavigateTo(result.ImpersonationUrl, forceLoad: true); } }
function submitForm(formName) { var form = document.getElementById(formName); form.submit(); } function submitFormWithAntiforgeryToken(formName, uri, requestToken) { var form = document.getElementById(formName); // Check if the antiforgery token is present in the form, if the token is not present, create a new hidden input field for the token var tokenInput = form.querySelector('input[name=__RequestVerificationToken]'); if (!tokenInput) { { tokenInput = document.createElement('input'); tokenInput.type = 'hidden'; tokenInput.name = '__RequestVerificationToken'; form.appendChild(tokenInput); } } // Set the value of the token tokenInput.value = requestToken; // Update the form's action with the new URI and submit the form form.action = uri; form.submit(); }
Any ideas?

hi
I hard-coded the tenant ID and tested in a Blazor Server project. And it works

I found the problem. It works for me with hard-coded values. The problem is that SelectedTenantId and SelectedTenantUserName are set too late and are not included when the form is submitted.
I guess I'll have to write it in via JavaScript, or do you have a better solution?

I found another solution by creating a form around each button.
One more question: what is the purpose of the ReturnUrl? Is it to go to a specific page on the tenant or to return to a specific page when returning to the host?
Neither seems to work.

You can call the
await InvokeAsync(StateHasChanged)
after changing theSelectedTenantId
. Ensure the input has set the correct value. -

What can you tell me about the ReturnUrl?

hi
Add the code below to fix the ReturnUrl issue. I will fix it in the next version
Thanks
Configure<AbpAccountOptions>(options => { options.GetTenantDomain = (httpContext, tenantInfo) => { var returnUrl = ""; if (httpContext.Request.HasFormContentType) { var form = httpContext.Request.Form; if (form.ContainsKey("ReturnUrl")) { returnUrl = form["ReturnUrl"]; } } return Task.FromResult(httpContext.Request.Scheme + "://" + httpContext.Request.Host + httpContext.Request.PathBase + returnUrl); }; });

You can call the
await InvokeAsync(StateHasChanged)
after changing theSelectedTenantId
. Ensure the input has set the correct value.The problem was that the DOM had not yet been updated at that moment. I solved it as follows:
<form method="post" action="Account/ImpersonateTenant" id="impersonateTenantForm"> <input type="hidden" name="TenantId" value="@SelectedTenantId" /> <input type="hidden" name="TenantUserName" value="admin" /> </form>
private Guid SelectedTenantId { get; set; } private bool ShouldSubmitImpersonateTenantForm { get; set; } = false; protected override async Task OnAfterRenderAsync(bool firstRender) { // Submit the impersonateTenantForm after setting the tenant ID if (ShouldSubmitImpersonateTenantForm) { ShouldSubmitImpersonateTenantForm = false; await JS.InvokeVoidAsync("submitForm", "impersonateTenantForm"); } } private async Task OnImpersonateTenantClick(Guid tenantId) { SelectedTenantId = tenantId; ShouldSubmitImpersonateTenantForm = true; await InvokeAsync(StateHasChanged); }
function submitForm(formName) { var form = document.getElementById(formName); form.submit(); }
