Terraform import for Microsoft.Communication/communicationServices/smtpUsernames@2025-09-01 uses incorrect API version #1043
Description
When attempting to import a SMTP username resource the provider by default is trying to use an incorrect API version that doesn't exist for this resource which is api version 2025-05-01-preview:
terraform import 'azapi_resource.smtp_username[0]' "/subscriptions/[REDACTED]/resourceGroups/[REDACTED]/providers/Microsoft.Communication/communicationServices/[REDACTED]/smtpUsernames/smtp-user"
│ Error: Failed to retrieve resource
│
│ reading Resource: (ResourceId
│ "/subscriptions/[REDACTED]/resourceGroups/[REDACTED]/providers/Microsoft.Communication/communicationServices/[REDACTED]/smtpUsernames/smtp-user"
│ / Api Version "2025-05-01-preview"): GET
│https://management.azure.com/subscriptions/[REDACTED]/resourceGroups/[REDACTED]/providers/Microsoft.Communication/communicationServices/[REDACTED]/smtpUsernames/smtp-user"

│ RESPONSE 400: 400 Bad Request

│ {
│ "error": {
│ "code": "NoRegisteredProviderFound",
│ "message": "No registered resource provider found for location 'global' and API version '2025-05-01-preview' for type 'CommunicationServices/SmtpUsernames'. The supported api-versions are '2024-09-01-preview, 2025-01-25-preview, 2025-09-01, 2025-09-01-preview'. The supported locations are 'global'."

│ }
│ --------------------------------------------------------------------------------
When passing in a valid API version, in this case 2025-09-01, the import is a success
terraform import 'azapi_resource.smtp_username[0]' "/subscriptions/[REDACTED]/resourceGroups/[REDACTED]/providers/Microsoft.Communication/communicationServices/[REDACTED]/smtpUsernames/smtp-user?api-version=2025-09-01"
Import successful!
The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.
This is the terraform code used for the import:
resource "azapi_resource" "smtp_username" {
count = 1
type = "Microsoft.Communication/communicationServices/smtpUsernames@2025-09-01"
location = "global"
parent_id = azurerm_communication_service.acs.id
name = "smtp-user"
schema_validation_enabled = false
body = {
properties = {
entraApplicationId = azuread_application.app.client_id
tenantId = data.azurerm_client_config.current.tenant_id
username = "smtp"
}
}
depends_on = [azurerm_email_communication_service_domain_sender_username.sender-username]
}
Ideally the import would use the latest stable version of the API.
